Acne: the full therapy pathway
From a first over-the-counter routine to the prescriptions and procedures dermatologists use when products aren't enough — what the steps are, and why they're ordered the way they are.
Before anything else
Not everyone should start at the bottom of this pathway. These presentations are reasons to
see a clinician without waiting out an over-the-counter trial first.
- Deep, painful nodules or cysts See a dermatologist soon
Nodulocystic acne is the presentation most likely to scar, and topical products rarely control it. This is the clearest case for skipping the OTC ladder and seeing a dermatologist directly.
- Any scarring — pitted, raised, or forming now See a dermatologist soon
Scarring does not require deep cysts — small inflamed lesions can scar too, and in people prone to it, scars form earlier than expected. Scars are permanent once established and can only be treated after the acne itself is controlled, so visible scarring is a reason to escalate now rather than to finish a trial period.
- Acne causing real distress or withdrawal See a dermatologist soon
How much the acne affects your life is part of how severe it is, not a separate question from it — two people with the same number of lesions can be affected completely differently. Significant psychological impact is a recognised reason to escalate treatment on its own, whatever the skin looks like to someone else.
- Sudden severe acne with other changes Worth a clinician visit
Acne that appears abruptly and severely, especially alongside irregular periods, excess hair growth, or rapid change, can point to a hormonal driver worth a clinician's assessment rather than a skincare fix.
- Acne fulminans-type presentation Seek care quickly
A rare, abrupt eruption of severe ulcerating lesions, sometimes with fever or joint pain, is a dermatological urgency — seek care quickly rather than treating it as ordinary acne.
Which part of this pathway is yours?
Five presentations are mapped on this page and only one of them is probably yours. Six questions, about a minute, and the rest of the page rearranges itself around your answers — the branch that applies, the checkpoint you're actually standing at, and what would have to change for the next step to be the right one.
Nothing you tap is sent anywhere. The answers stay in this browser so the page still knows where you were if you come back, and a single button clears them.
One thing to be clear about. This places you on a map. It does not diagnose you, and it cannot see your skin — several conditions look like acne and are treated nothing like it. If what you get back doesn't match your experience, trust your experience and read the whole page.
What this looks like
Dermatologists don't grade acne by a single number so much as by the kinds of lesions present, how widespread they are, and what the acne is leaving behind. This orientation framework is drawn from published clinical staging — it's a way to locate yourself, not to assign yourself a diagnosis.
Comedonal
Clogged pores without much inflammation — the pore-plugging lever dominating over the bacterial and inflammatory ones.
What it looks like: Blackheads (open comedones) and whiteheads (closed comedones), often across the forehead, nose and chin, with little redness or tenderness.
Mild-to-moderate inflammatory
Comedones plus genuinely inflamed lesions, but not deep ones — all four levers now in play.
What it looks like: Red papules and pus-topped pustules mixed with comedones. Sore to the touch, but the lesions sit at the surface rather than as deep lumps.
Nodulocystic (severe)
Deep, inflamed lesions that involve the lower part of the follicle — the presentation most likely to scar.
What it looks like: Painful nodules and cysts — firm or fluctuant lumps under the skin, sometimes connected, often on the jaw, cheeks, chest or back. This is the stage where waiting has the highest cost.
Three things that change the plan regardless of severity
Scarring — at any severity
Scarring changes the plan regardless of how many lesions you have. Once a scar forms it doesn't resolve on its own, and scar treatment works best after the acne itself is controlled — so active scarring is a reason to escalate now, not after another product cycle.
Post-inflammatory pigment forming
The brown or dark marks left after lesions heal are pigment, not scarring — an important distinction, because they will fade on their own over months whereas true scarring will not. True scars are a change in the tissue itself: a depression where skin has been lost, or a raised thickening. Flat marks that are only a colour change are neither, however long they take to go. What both have in common is that continued inflammation makes them worse, and sun exposure darkens the pigment faster than any treatment lightens it.
Psychosocial burden
How much acne is affecting your life is a legitimate part of staging in its own right, not a soft add-on. Guidelines recognize significant psychological distress as an escalation reason even when the lesion count looks moderate — the impact is the measure that matters here.
What else it could be
- Rosacea (papulopustular) — Papules and pustules on a background of persistent central-face flushing, usually without comedones — and treated very differently.
- Folliculitis (including fungal/Malassezia) — Itchy, uniform small bumps, often on the forehead, chest and back; the fungal kind can worsen on antibiotics.
- Perioral dermatitis — Clustered small papules around the mouth or nose, frequently linked to topical steroid use, needing a different approach entirely.
If your "acne" itches, spared no comedones, sits only around the mouth, or flares on standard acne treatment, those are reasons to have a clinician confirm what it actually is before treating it harder.
Why it happens
Acne forms when four things overlap inside a pore: the skin oversheds cells that plug the follicle, oil (sebum) builds up behind the plug, a normally harmless skin bacterium (Cutibacterium acnes) proliferates in that environment, and the immune system responds with inflammation. Every effective treatment works by targeting one or more of these four levers — which is also why combining mechanisms usually beats piling on more of the same one.
Anyone who has been treating acne with over-the-counter products and is wondering whether it's time for something stronger — and anyone who suspects, from the kind of acne they have, that products were never going to be enough. It walks the whole arc so you can see where you are on it.
Orientation, not diagnosis. This page helps you orient — it is not a diagnosis. Several conditions can look like acne (rosacea's papules and pustules, folliculitis including the fungal kind, and perioral dermatitis are the common look-alikes), and telling them apart is a clinical judgment a page can't make. Use this to understand the shape of care and to have a better-informed conversation with a clinician, not to self-diagnose.
Everything on this page is available without a prescription The over-the-counter pathway
Over-the-counter acne care is genuinely effective for the right presentation, and it's where almost everyone should start when the acne is comedonal or mild-to-moderate inflammatory. The workhorses are few, well-evidenced, and — importantly — most powerful when combined rather than rotated. The realistic goal at this level is meaningful reduction over about three months, not overnight clearing.
Appropriate for: Comedonal and mild-to-moderate inflammatory acne, with no scarring, no deep nodules or cysts, and no significant distress. If those modifiers are present, the honest answer is that OTC was likely never the right ceiling.
One route, and it is the same route whether the acne is mild or moderate. What changes between people is not which product they start with — it is how quickly their skin tolerates the full combination. So this is a ramp rather than a series of experiments: you are building up to one regimen, not auditioning four of them.
The thing most people get wrong
Acne treatment is not a sequence of single-product trials. There is no need to give one active three months, decide it failed, and move on to the next — that is how a year disappears. The actives work on different parts of the same process, so they are used together, and the reason to introduce them one at a time is tolerance, not evidence. Once your skin is holding the combination, the clock that matters starts.
This section reflects review comments from a consultant dermatologist.
Four rules that matter more than which brand you buy
- Retinoids go on in the evening. They raise sun sensitivity, and daylight undoes some of the work.
- Build up, don't dive in. Short contact first — apply, leave five minutes, wash off — then longer, then overnight. Skin that is raw and peeling is skin that stops treatment.
- Moisturiser and sunscreen are not optional extras here. Dryness is the single commonest reason people abandon a retinoid that was working.
- Do not add a fourth active because progress feels slow. Three actives is not three times the result; it is a barrier that can no longer tolerate any of them.
Answer as you go and the chart tracks where you are. Nothing is sent anywhere.
- Week 0You are here
Get the base right
A skin surface that can take an active without giving up on it in a fortnight.
What this step involves
Morning
- Cleanse Gentle, non-foaming or low-foaming, once. Squeaky-clean is the wrong target — stripping the skin provokes more oil, not less. Browse all cleansers →
- Moisturise Every morning, whatever your skin type, including oily. This is what makes the next four steps survivable. Browse all moisturizers →
- Sunscreen Daily. It is also the single most effective thing available over the counter for the dark marks that lesions leave behind. Browse all sunscreens →
Evening
- Cleanse Same cleanser. Pat dry and leave it dry — actives applied to damp skin absorb faster and sting more.
Why this step: Nothing here treats acne. It exists so that what comes next can be tolerated for three months rather than abandoned in three weeks.
Ready for the next step?
Is your skin calm — no raw patches, no active peeling, nothing stinging?
Yes, it's settled: Move to step 1. Go to step 1 ↓
No, it's irritated: Stay here a week or two. Starting a retinoid on an already-compromised barrier is the fastest route to stopping it.
- Weeks 1–2You are here
Start the retinoid — short contact
Introduce adapalene without the fortnight of peeling that makes people quit.
What this step involves
Morning
- Unchanged Cleanse, moisturise, sunscreen, exactly as step 0.
Evening
- Cleanse and dry Completely dry — give it a few minutes.
- Adapalene 0.1%, five minutes, then wash off A pea-sized amount for the whole face — not dabbed on spots. Leave it five minutes, rinse, then moisturise. Three nights in the first week. This is called short contact, and it is how you find out what your skin will take before it tells you the hard way. Browse all adapalene products →
- Moisturise Straight after rinsing.
Why this step: Retinoids are the most effective topical treatment for blackheads and whiteheads, and they work on the plug that starts every lesion — including the inflamed ones. Almost all of their reputation for being intolerable comes from people starting at full strength, overnight, on day one.
What's normal: Expect some dryness. Do not expect raw, weeping or persistently stinging skin — that is a signal to slow down, not to push on.
Ready for the next step?
After a week, is anything still stinging or peeling the next morning?
Yes: Hold at five minutes, three nights a week, for another week. There is no prize for arriving early. Go to step 2 ↓
No, it's fine: Move to step 2 — longer contact.
- Weeks 2–4You are here
Build the retinoid to nightly
Adapalene left on overnight, most nights.
What this step involves
Morning
- Unchanged Cleanse, moisturise, sunscreen.
Evening
- Cleanse and dry As before.
- Adapalene, left on Extend the contact time first — fifteen minutes, then thirty, then overnight — before increasing the number of nights. Build towards nightly. Browse all adapalene products →
- Moisturise Generously, over the top. Applying it before the retinoid as a buffer is also fine and does not stop it working.
Why this step: Overnight contact is where a retinoid does its work. This is also the fortnight in which skin most often looks worse — lesions that were already forming come to the surface together. That is the treatment working through the backlog, not a reaction to it.
Ready for the next step?
Are you using it overnight, most nights, without the skin complaining?
Yes: Move to step 3 — this is where the combination starts. Go to step 3 ↓
Not yet: Stay here. The ramp has no deadline, and arriving at the full combination with intact skin is the entire point.
- Weeks 4–6You are here
Add benzoyl peroxide
The combination that most of the evidence sits behind.
What this step involves
Morning
- Cleanse Gentle, once. Browse all cleansers →
- Benzoyl peroxide 2.5–5% A thin layer over the areas that break out, not a dab on individual spots. Lower strengths work as well as higher ones and irritate less. A wash is a reasonable alternative if a leave-on is too much. Browse all benzoyl peroxide products →
- Moisturise and sunscreen Benzoyl peroxide is drying. This step is what makes it liveable. Browse all moisturizers →
Evening
- Cleanse, adapalene, moisturise As step 2. Benzoyl peroxide in the morning, retinoid at night.
Why this step: Benzoyl peroxide works on the bacteria and the inflammation; the retinoid works on the plug. Together they cover more of the process than either does alone, and using benzoyl peroxide alongside any antibiotic — now or later — is what limits resistance.
The simpler version of this step
A single fixed-dose product containing both adapalene and benzoyl peroxide replaces the two separate steps entirely: one application, once a day. Since 2026 this combination has been available over the counter in the US for ages 12 and up, having previously required a prescription. It is a very reasonable thing to start on directly, at either severity.
If you have red, inflamed spots right now
There is no reason to work up to this slowly one active at a time. Where there is visible inflammation it is reasonable to use the products together from the start, adjusting the pace only if the skin objects.
Ready for the next step?
Are you on both — benzoyl peroxide in the morning, adapalene at night, or one fixed combination daily?
Yes: The clock starts now. Twelve weeks. Go to step 4 ↓
Not yet: Stay at whichever part you are tolerating and add the other when you can.
- Week 6 onwards · optionalYou are here
Add azelaic acid in the morning — if marks are the problem
Address the brown or red marks left behind, without disturbing the evening routine.
What this step involves
Morning
- Azelaic acid 10%, whole face Applied to the whole face in the morning rather than spot-treated. It works on the bacteria, the inflammation and the pigment left behind, and it is the most tolerable of the four. Browse all azelaic acid products →
- Then moisturiser and sunscreen Sunscreen matters most here — marks darken with sun exposure faster than any cream can lighten them. Browse all sunscreens →
Evening
- Unchanged Retinoid and benzoyl peroxide stay in the evening.
Why this step: Keeping azelaic acid to the morning and the retinoid to the evening is what makes a third active tolerable. It is also the one active on this list that treats the marks as well as the spots, which for many people is the part that actually bothers them.
Optional. If marks are not your problem, the combination at step 3 is a complete over-the-counter regimen and adding to it buys irritation rather than results.
Ready for the next step?
Are marks left behind by old spots a bigger issue for you than the spots themselves?
Yes: Add it in the morning. Give it longer than you want to — pigment fades over months. Go to the checkpoint ↓
No: Skip this step. You are already on a complete regimen.
Twelve weeks on the full combination
Twelve weeks from the day you were using the combination consistently — not from the day you bought the first tube.
How to judge it: Compare against a photograph, or against a specific memory, from three months ago. Skin does not change fast enough to judge in a mirror day to day, and the gradual version of improvement is invisible from the inside.
Compared with three months ago, are fewer new spots appearing?
It is working. Do not stop.
This is the answer the checkpoint exists to find, and the instruction that follows it is the counter-intuitive one: change nothing. Acne treatment is maintenance rather than a course — the regimen that cleared your skin is the regimen that keeps it clear, and the commonest way people lose the ground they have gained is stopping once it looks good.
Ambiguous — and worth another opinion rather than another product.
Partial improvement after a genuine trial can mean the approach is right and needs longer, or right and needs something added. Those look identical from the outside, which is exactly the situation a clinician is useful in. Going in with dates, photographs and what you actually used makes that a five-minute conversation instead of a guess.
This is the handover point.
Twelve weeks of the full combination, used properly, with no meaningful change is not a discipline failure and it is not a sign that you bought the wrong brand. It is the result this checkpoint exists to produce, and the point at which over-the-counter treatment has done what it can. What comes next is a prescription — a different tier of treatment, not a stronger version of the same one.
Stop escalating and reassess.
Skin that is raw, persistently stinging or reacting rather than adjusting has not had a fair trial of anything — the treatment never got a proper run, so its effectiveness for you is still unknown. Drop back a step, extend the ramp, and if a gentler version is still not tolerated, that in itself is a reason to see someone.
Do not wait out the twelve weeks if this happens
Scarring does not only follow deep cysts — small lesions can scar too, and scarring is the one consequence of acne that treatment cannot undo afterwards. If you can see pitted or raised marks forming at any point, that is a reason to seek more effective treatment now rather than at the end of a trial period. The same applies if the acne is affecting how you live: distress is part of severity, not a separate question from it.
Whatever step you are on, treatment should be reviewed every few months rather than continued indefinitely on the assumption it is helping. Long stretches of treatment without clear control are how scarring develops unnoticed — which is why the checkpoints here ask for a comparison rather than an impression.
Where the over-the-counter pathway ends
Everything above is the over-the-counter pathway, and every part of it is available without seeing anyone. Beyond this point the treatments are prescription-only — not because they are stronger versions of the same thing, but because they work differently, need monitoring, or have to be matched to a pattern that takes an examination to identify. The prescription pathway is set out separately below, and reaching it is a normal outcome rather than a failure of the one above.

What to expect
Prescription treatments fail for the same reasons OTC routines do — stopping too soon, expecting results faster than any acne treatment delivers, or quitting during the adjustment window when skin can look worse before it looks better. Nearly every effective acne treatment takes on the order of 8–12 weeks to show its real effect, and some cause an early purge. Knowing that in advance is often the difference between a treatment that works and one that gets abandoned at week three.
- Give a new treatment a fair, consistent trial before judging it — inconsistency is the most common reason things 'don't work'.
- Expect an adjustment period with retinoids and some orals; an early flare or dryness is usually not a reason to stop.
- Keep the gentle supporting routine going alongside a prescription — moisturizer and sunscreen make stronger treatments tolerable.
- Stay in contact with the clinician about side effects rather than quitting silently.
This is where the site stays useful during clinical care, not just before it: a gentle, non-irritating supporting routine built around a prescription — the calm-everything-else approach that makes a tretinoin course or an isotretinoin regimen bearable — is as much a personalization problem as any the routine tools already solve. The relationship continues alongside the clinician's plan instead of competing with it.
What would bring you back sooner
Whatever step you are on, these do not wait for the end of a trial period. They are the same
presentations listed at the top of this page — repeated here because that is where they
matter, rather than where they were easiest to put.
- Deep, painful nodules or cysts See a dermatologist soon
- Any scarring — pitted, raised, or forming now See a dermatologist soon
- Acne causing real distress or withdrawal See a dermatologist soon
- Sudden severe acne with other changes Worth a clinician visit
- Acne fulminans-type presentation Seek care quickly
Prescription only — from here on, this is a clinician's decision The prescription pathway
Why this tier exists. What OTC cannot do: reliably control deep nodular or cystic acne, prevent or treat scarring, or resolve a hormonal driver. No over-the-counter product removes a scar or shrinks a cyst. When those are the problem, more products is the wrong axis to add on.
Acne treatment isn't one ladder — it's a few, depending on what kind of acne you have. Here is the whole thing on one screen: how far each kind escalates, and what has to happen before it does.
The same pathway in full below — each step names what it involves, why it sits where it does, and what tells you it's time to move up. Tap any therapy to jump to its detail.
Comedonal acne (blackheads & whiteheads)
Clogged pores with little inflammation and no scarring. The plug is the target, so the ladder leans on retinoids and pore-clearing exfoliants.
You reach this column when: No meaningful reduction after a fair trial, or the acne is turning inflammatory and spreading.
- Prescription topical
Prescription topical retinoid
Why this step sits here: When OTC adapalene isn't enough, a clinician can prescribe a stronger or better-tolerated retinoid (tretinoin, tazarotene, trifarotene) or a fixed-dose combination. The lever is the same; the potency, formulation, and guidance are what change.
Within this step the choices differ more in feel than in mechanism — all of them work the same lever:
- Tretinoin, tazarotene or trifarotene backed by large randomized trials
The strength-and-formulation ladder. Tazarotene tends to be the most potent and the most irritating, adapalene the most forgiving, tretinoin the long-established middle ground.
- A retinoid–benzoyl peroxide combination backed by large randomized trials
When stray inflamed spots keep joining the clogged pores — one nightly product covering both levers is tidier than layering two.
Which retinoid, at what strength, in which base — that's a matching problem between your skin and the molecule, and it's what a prescriber is for.
-
Once it's clear: keeping pores clear
Comedonal acne is a production problem — pores that keep making plugs — so the retinoid that cleared it is also what keeps it cleared. Stepping down to a few nights a week often maintains the result; stepping down to zero usually doesn't. The marks lesions left behind fade on their own schedule, and daily sunscreen is what stops them overstaying it.
Mild-to-moderate inflammatory acne
Red, sore papules and pustules mixed with comedones, no deep nodules and no scarring. All four levers are active, so the ladder combines mechanisms.
You reach this column when: Inflammation persists or worsens after a fair trial, lesions are getting deeper, or marks and early scarring are appearing.
- Prescription topical
The first prescription: stronger topicals, usually combined
Why this step sits here: The first prescription is usually still a cream or gel — what changes is potency and combination. A prescriber reaches either for a product that works two or three of the four levers in one application, or for a topical matched to something specific in your picture: the hormonal signal, a tendency to dark marks, how much irritation your skin will accept.
These aren't a sequence to work through — a prescriber picks by fit:
- Fixed-dose combination gels backed by large randomized trials
The usual default: one nightly product carrying a retinoid plus benzoyl peroxide — or all three mechanisms, antibiotic included — beats layering the parts separately, for results and for actually sticking with it.
- Clascoterone backed by large randomized trials
When oiliness and the hormonal signal are front and centre. It's the only topical that blocks that lever, works across sexes, and joins a retinoid rather than replacing it.
- Topical dapsone backed by large randomized trials
The gentle option — often the pick for adult women, and for deeper skin tones where irritation itself leaves marks worth avoiding.
- A topical antibiotic, benzoyl peroxide alongside backed by large randomized trials
Extra antibacterial reach when inflammation is the loudest feature — always partnered with benzoyl peroxide so resistance never gets a foothold.
When to move up
- A fair trial
- Around 12 weeks on the prescribed regimen, used as written — the prescription tier runs on the same honest clock the shelf did.
- Improvement looks like
- Inflamed lesions clearly declining month over month — a trend your photos agree with, not just a good fortnight.
- Move up if
- A full topical regimen can't hold moderate acne, lesions are getting deeper, or fresh marks and early scars are appearing despite it.
→ The next step up this pathway.
Where are you with this step?
-
- Prescription oral
Adding an oral medicine — for a season, not forever
Why this step sits here: When good topicals can't control moderate acne on their own, the next move adds a pill alongside them — not instead of them. Two very different pills can fill that slot, and which one fits is among the most individual calls on this page.
The two candidates for the added pill:
- A time-limited oral antibiotic backed by large randomized trials
The standard add for flared, widespread inflammation: doxycycline for about three months, the topicals continuing throughout, then stopped while they hold the ground it gained.
- Hormonal therapy, for women backed by large randomized trials
The slower-burning equal. Antibiotics lead over the first three months; by six, hormonal therapy has caught up — and of the two, it's the one that can be stayed on.
When to move up
- A fair trial
- One full antibiotic course — about three months, topicals running throughout — or up to six months for hormonal therapy, which is judged on a slower clock.
- Improvement looks like
- Genuine control by the end of the course, and — the part that matters most — control that survives the antibiotic stopping.
- Move up if
- The acne never came under control, or it returns as soon as each course ends. Rolling from one antibiotic round into another is the pattern guidelines specifically warn against.
→ The next step up this pathway.
Where are you with this step?
-
- Specialist care
When the standard playbook isn't enough
Why this step sits here: Acne that has been through good topicals and a proper oral course and still isn't controlled has earned the serious options — and serious here means effective, not desperate. This tier is also where relapses-after-every-course belong, because repeating what didn't hold is the one move the evidence argues against.
What a dermatologist weighs at this point:
- Isotretinoin backed by large randomized trials
The only treatment working all four levers at once, and the only one that commonly ends acne rather than managing it — a defined course of some months under close supervision.
- Hormonal therapy, if that lever is still unplayed backed by large randomized trials
Women who took the antibiotic route first may still have this entire mechanism untried.
- The 1726-nm laser backed by smaller studies
The non-drug route: three sessions of light aimed at the oil glands themselves. Real results in studies across skin tones — and a real, uninsured price.
Which of these — or what combination — is the appointment. Each carries its own monitoring, timelines and trade-offs, and the right pick depends on your history, your bloodwork, and what your skin has already shown it does under treatment.
-
Once it's clear: staying clear
Clearing acne and keeping it away are different jobs, and the second is quieter: a topical retinoid, continued daily after the lesions are gone, with benzoyl peroxide staying in the mix if it was part of what worked. What never stays on is the antibiotic — oral or topical, it stops once control is reached, and the retinoid holds the line from there. Skipping maintenance is the most common way a hard-won result unravels.
Hormonal-pattern acne in adult women
Acne concentrated on the lower face and jawline, often flaring with the menstrual cycle and persisting into adulthood. The over-the-counter start is the same as anyone else's; what's distinctive is that the driver sits upstream of what a topical can reach, so this is the branch where a fair trial most often runs out.
You reach this column when: The cyclical flare arrives on schedule and unchanged, or the pattern was moderate-to-severe from the outset.
- Prescription topical
Topicals, including clascoterone
Why this step sits here: For a hormonal pattern, a topical that blocks the androgen signal (clascoterone) is an option that targets the actual driver locally, and can be combined with a retinoid. It's placed early because it addresses cause rather than consequence without systemic exposure.
When to move up
- A fair trial
- About 12 weeks of consistent use.
- Improvement looks like
- Fewer cyclical flares and a calmer jawline over successive cycles.
- Move up if
- Flares persist across cycles or the pattern is moderate-to-severe from the outset.
→ The next step is a clinician, not another product.
Where are you with this step?
- Prescription oral
Systemic hormonal therapy
Why this step sits here: Combined oral contraceptives and spironolactone address the hormonal driver systemically and are well-suited to this pattern. The trial record has caught up with the practice: SAFA showed spironolactone beats placebo in adult women, and the 2024 FASCE head-to-head found it outperforming doxycycline itself by six months — treating the driver, not borrowing an anti-inflammatory.
When to move up
- A fair trial
- Three to six months — the slowest clock on this page, because these treatments work through the cycle rather than on the lesion.
- Improvement looks like
- Each cycle's flare arriving smaller than the last, and the baseline between flares steadily calmer.
- Move up if
- Six months without genuine change, or acne that is deep, scarring or accelerating while you wait.
→ The next step up this pathway.
Where are you with this step?
- Specialist care
If the hormonal route isn't enough
Why this step sits here: A hormonal pattern that doesn't yield to hormonal therapy hasn't run out of road — it joins every other stubborn presentation at the final tier, where isotretinoin works regardless of what upstream signal is driving the oil.
How spironolactone, a combined pill, and isotretinoin sequence around each other — and around pregnancy plans in particular — is precisely the conversation this appointment exists to have.
Once it's clear: what staying clear means here
Hormonal therapy is the exception to stop-when-clear: it works while taken, so keeping the result usually means keeping the treatment, reviewed periodically with the prescriber rather than renewed on autopilot. A topical retinoid running alongside protects the gains at skin level — and is what remains standing if the systemic treatment ever stops.
Nodulocystic / severe / scarring acne
Deep painful nodules or cysts, acne that is scarring, or acne causing significant distress. This branch is a bypass — it should skip the OTC ladder and go to a dermatologist.
If this describes you, the fair-trial clock doesn't apply. The clearest next step is a dermatologist appointment, not another product.
- Specialist care
See a dermatologist directly
Why this step sits here: Severe, nodular, or scarring acne rarely responds to topicals and carries the highest scarring cost per week of delay. Depending on the picture, a dermatologist may combine systemic and topical therapy, treat individual nodules directly, or move toward isotretinoin — decisions that are the appointment's whole purpose.
What the appointment reaches for, depending on the picture:
- Isotretinoin, often first backed by large randomized trials
For nodulocystic or scarring acne this is a guideline first-line, not a last resort — the most effective option there is, and the likeliest to end the disease rather than hold it.
- Oral antibiotic plus combination topicals backed by large randomized trials
The other opening move: roughly seven in ten people with severe acne reach clear or almost clear on this three-part approach.
- An injection for a single stubborn lesion backed by smaller studies
Dilute corticosteroid into one painful nodule settles it in days — a spot-fix deployed alongside the main plan, never instead of it.
There's no product step to try first here, and no clock to run down. The value of this page ends at the clinic door — everything past it depends on an examination.
-
After the severe chapter
Most people who complete an isotretinoin course stay clear; about one in five needs some further treatment within a couple of years, more often younger patients, adult women, and acne on the trunk. That's a statistic with a plan attached — retreatment or a maintenance retinoid picks it up. After an antibiotic-led plan, the topicals simply continue as the standing guard.
Treating acne scars
Scar treatment is a separate track from acne treatment, and the sequencing rule is firm: control the acne first, then treat scars. Working on scars while acne is still active means treating a moving target and risking fresh ones. The right procedure depends on the scar type, which is why this is a map rather than a ladder.
Atrophic scars (rolling, boxcar, icepick)
Depressed scars are matched to technique by shape and depth — subcision for tethered rolling scars, fractional laser or microneedling for broad texture, TCA CROSS for narrow icepick scars. Often several are combined over time.
Post-inflammatory pigment (dark marks)
The flat brown or dark marks are pigment, not true scars, and often fade with time, sun protection, and the same topicals used for pigmentation — a gentler track than textural scar work.
Raised (hypertrophic/keloid) scars
Raised scars are treated differently from depressed ones — intralesional corticosteroid is a common first step, and aggressive resurfacing can worsen a keloid-prone tendency.

When the rules change
The ladders above quietly assume an adult face and no pregnancy. These are the situations where the standard answers change — and what changes about them.
Acne during pregnancy
Pregnancy takes several of this page's workhorses off the table at once, which can sound like “nothing until the baby comes.” That isn't the reality — the starting point just moves.
What can be used
- Azelaic acid — the usual first choice, working on the acne and the marks it leaves at the same time
- Topical erythromycin or clindamycin, where a prescriber wants antibacterial reach
- Benzoyl peroxide, generally regarded as compatible — worth confirming for your own situation
- For moderate-to-severe acne: short courses of certain oral antibiotics (erythromycin or cephalexin), decided together with the obstetric team
What comes off the table
- Every retinoid — over-the-counter adapalene, prescription tretinoin, tazarotene, and above all oral isotretinoin, which causes severe birth defects
- Spironolactone and the combined pill's acne role
- Oral tetracyclines (doxycycline and relatives), which affect a baby's developing bones and teeth
Treatment decisions in pregnancy are made with the clinician managing the pregnancy, not around them. The pregnancy-safe checker on this site can screen what's already on your shelf before that conversation.
Acne at other ages
Outside the teens-and-adults window, acne follows different rules — and in one age band it's a finding that always deserves a clinician rather than a product.
- Newborns (first 6 weeks)
- Common, often not true acne at all, and it resolves on its own. A paediatrician can confirm; treatment is rarely needed.
- Infants (6 weeks to 2 years)
- Genuine acne can occur here and can scar, so it warrants a clinician visit — and an unusual picture sometimes prompts a growth-and-hormones check.
- Children (roughly 2 to 7)
- The rare one that matters. Acne at this age isn't normal — the hormones that drive it should still be quiet — so it always deserves medical evaluation, not skincare.
- Preteens (7 to 12)
- Increasingly common and usually just puberty announcing itself early. The same treatment principles apply in age-adapted strengths, with one firm rule: tetracycline antibiotics only once adult teeth are established, around age eight or later.
How an appointment actually happens, what to take to it, and how to keep your skin liveable while a prescription or procedure does its work.
What seeing a dermatologist actually looks like
A dermatologist is the specialist for acne, but where dermatology access or cost is a barrier, a primary-care clinician is a legitimate first step — they can start standard prescriptions and refer on if needed. You don't have to solve everything before booking; getting seen is the point.
What to bring
- A list of every product and prescription you've tried, and for how long — the routine tools on this site can generate this for you.
- Which treatments helped, which didn't, and any that caused irritation or reactions.
- Photos of your skin on a bad day, since acne can look calmer in a clinic than it does at home.
- Your other medications, and whether you are or may become pregnant — it changes what can be prescribed.
Questions worth asking
- What kind of acne is this, and what's driving it in my case?
- What does success look like, and how long until I should expect to see it?
- What are the side effects of what you're recommending, and what should prompt me to call you?
- Is anything here a concern for pregnancy, now or later?
- What's the plan if this doesn't work — what's the next step?
Cost and access. Costs vary widely by treatment and coverage; generic topicals and oral options are often inexpensive, while procedures are typically out-of-pocket. Ask directly about cost and about generic or lower-cost equivalents — a good clinician expects the question.
Fear and uncertainty about the appointment itself is a documented reason people delay care. A first visit is usually a straightforward conversation and skin exam — treating it as a normal, navigable event is part of getting your acne handled.
Finding someone to see
How you reach a dermatologist depends entirely on where you are, and the route matters as much as the referral — in several of these systems the appointment starts with a GP by design, not as an obstacle.
- US Find a Dermatologist American Academy of Dermatology Search by location, condition and procedure. Board certification is what the directory verifies.
- Canada Find a Dermatologist Canadian Dermatology Association Certified dermatologists by city or postal code. A family doctor's referral is usually needed first.
- UK Acne — when to see a GP NHS The route runs through a GP, who treats most acne directly and refers on where a specialist is warranted. Isotretinoin is specialist-initiated only.
- Australia How to see a dermatologist (PDF) Australasian College of Dermatologists A two-page factsheet on referrals, waiting times and what a private appointment costs.
A region missing from this list means we have no verified link for it, not that no route exists.
Skincare alongside therapy
Almost everything above is a treatment you're given. This is the part you're left to work out on your own, and it's where most courses quietly go wrong — not because the drug failed, but because the skin around it got too dry, too raw, or too irritated to keep going. Prescriptions fail for the same reason over-the-counter routines fail: people stop.
The supporting routine is almost the same whatever you're on, and it's deliberately boring: a gentle cleanser, a moisturizer, a daily sunscreen. The treatment is doing the work. Everything else exists to keep you able to tolerate it — which means the job of these products is to not interfere. This is the one place on this page where the product side of the site genuinely helps during clinical care rather than instead of it.
While you're on a retinoid — over-the-counter or prescription
Retinoid courses rarely fail because the molecule didn't work; they fail in week three, when the skin is flaking and stinging and it feels like it's making things worse. That window is survivable, and the supporting routine is what gets you through it.
Do
- A pea-sized amount for the whole face, on dry skin — more isn't faster, it's just more irritation.
- Moisturize as much as you need, before or after. Applying moisturizer first ("buffering") doesn't cancel the retinoid out.
- Sunscreen every morning. Retinoids increase sun sensitivity, and sun damage undoes what you're taking them for.
- Start two or three nights a week and build up as your skin allows.
Avoid
- Scrubs, and stacking acids on retinoid nights while you're still adjusting.
- Astringents, alcohol-heavy toners, and anything that tingles — that's irritation, not efficacy.
- Waxing on treated skin; it can lift the skin itself.
What that looks like on a shelf: a gentle cleanser, a barrier moisturizer, a daily sunscreen.
While you're on isotretinoin
This is the course where the supporting routine stops being optional. Dry, cracked lips are close to universal, and dryness of the skin and eyes is expected rather than a sign something is wrong. Nothing here is a substitute for what your dermatologist tells you — they're monitoring you, and they win every disagreement with this page.
Do
- Keep a lip ointment within arm's reach and reapply it more often than feels reasonable. Everyone underestimates this one.
- A richer moisturizer than you think you need, and an occlusive to seal it at night.
- A gentle, non-foaming cleanser — skin is thinner and more fragile during a course.
- Sunscreen daily; photosensitivity comes with the drug.
- Tell any provider you're on isotretinoin before they do anything to your skin.
Avoid
- Every other active. No retinoids, no acids, no benzoyl peroxide — the drug is doing all of it, and layering actives on top only buys you damage.
- Waxing, laser, dermabrasion and other resurfacing during the course and for a period afterwards. Skin heals differently on isotretinoin; your dermatologist will tell you when it's safe, and the timing is genuinely their call rather than a fixed number.
- Picking at cracked lips or dry patches.
What that looks like on a shelf: a lip ointment, a barrier moisturizer, a gentle cleanser, a daily sunscreen.
While you're on an oral antibiotic
The antibiotic is time-limited by design. The topical treatment alongside it is what holds the result once the course stops — which makes the least interesting part of the plan the one that decides whether the acne comes back.
Do
- Keep using the topical you were prescribed, all the way through and after. This is the whole point of the pairing.
- Sunscreen daily — doxycycline in particular can make you burn faster and harder than you expect.
- Take it with a full glass of water and stay upright afterwards; the capsules can irritate the food pipe.
Avoid
- Treating the antibiotic as the treatment and quietly dropping the topical once things improve.
- Long unprotected sun, which is a bigger deal on a tetracycline than people anticipate.
What that looks like on a shelf: a daily sunscreen, a gentle cleanser.
After an in-office procedure
Start here: the aftercare instructions from whoever performed the procedure override everything on this page. They know what was done and how deep it went; this page doesn't. What follows is only the general shape of it.
Do
- Bland everything. A gentle cleanser and a plain occlusive is usually the entire routine for the first stretch.
- Strict sun protection. Freshly treated skin pigments readily, and that risk is higher in richer skin tones — it's the most common way a good result gets spoiled.
- Wait for your provider to clear you before reintroducing any active.
Avoid
- Actives — retinoids, acids, vitamin C — until you're told otherwise.
- Picking at crusting or flaking; that's how a treated scar becomes a new one.
- Booking a holiday in the sun straight after a resurfacing session.
What that looks like on a shelf: a gentle cleanser, a daily sunscreen.
While you're on hormonal therapy or clascoterone
The gentlest group to support. These don't tend to wreck the skin barrier the way a retinoid or isotretinoin can, so an ordinary supportive routine is genuinely enough — no special measures, and no need to buy anything new if what you have is working.
Do
- Keep the routine simple and consistent; these work over months, not weeks.
- Sunscreen daily, as much for the post-acne marks as for the acne.
- Give it several cycles before judging whether it's working.
Avoid
- Adding harsh actives out of impatience while the treatment is still building.
- Expecting a visible change in the first few weeks.
What that looks like on a shelf: a gentle cleanser, a barrier moisturizer, a daily sunscreen.
The supporting shelf
A gentle cleanser
A barrier moisturizer
A daily sunscreen
A lip ointment
These are supporting products, not treatments, and none of them will clear acne on their own — that's what the pathway above is for. They're ranked here on gentleness first: fragrance-free, low irritation risk, and only then on score. A product being absent from a list here isn't a mark against it; it just isn't the right thing to put on skin that a drug is already pushing. An earlier draft of this section suggested an occlusive ointment layer during treatment; it was removed on clinical review. Occlusion has a clear role in barrier repair on dry, eczema-prone skin, but its place in acne — where follicular occlusion is part of the problem — is not settled enough to recommend here.

Over the counter
Available without a prescription. Each one opens with what to look for on a label, which is the part that stays true regardless of which brand is on the shelf that month.
Over-the-counter Adapalene (OTC retinoid)
Over-the-counter topical retinoid
Avoid in pregnancy
Adapalene (OTC retinoid)
Over-the-counter topical retinoid
A third-generation retinoid available without a prescription at 0.1%, and — as of 2026 — also in a fixed OTC combination with benzoyl peroxide. The best-evidenced OTC active for acne.
At the shelf
Adapalene 0.1% gel — the only strength sold without a prescription in most markets.
One tube is one active, and 0.1% is the whole over-the-counter range: a product marketed as stronger is either a different retinoid entirely or a smaller quantity of the same thing. The fixed combination of adapalene with benzoyl peroxide — one product, once a day — is a very reasonable thing to start on directly, at either severity. Price varies several-fold across brands carrying the identical 0.1% gel, which is the clearest case on this page for buying on cost.
Watch out for: Serums listing retinol, retinyl palmitate or bakuchiol alongside acne claims are not adapalene and are not interchangeable with it.
Browse all adapalene products in our catalog →
How it works
Normalizes how the follicle sheds skin cells, dissolving the plug that starts every lesion and preventing new ones, with an anti-inflammatory effect on top.
What the evidence says well established
Topical retinoids are a strongly-recommended backbone of acne therapy in the 2024 AAD guidelines, effective for both comedonal and inflammatory acne.
Typical course
Once daily; expect an adjustment period of dryness and a possible purge over the first weeks, with meaningful improvement over about 12 weeks.
Commonly discussed side effects
- Dryness and peeling
- Redness and stinging early on
- Temporary purging
- Sun sensitivity
Worth knowing
- The most effective topical available for blackheads and whiteheads
- Introduce by contact time, not by strength — five minutes, then longer, then overnight
- Evening only: it raises sun sensitivity
- Pair with moisturiser and daily sunscreen
Pregnancy: Topical retinoids are generally avoided in pregnancy; anyone pregnant or planning pregnancy should choose a pregnancy-compatible active instead and confirm with a clinician.
Why it sits where it does: It sits at the base of the comedonal and inflammatory ladders because it acts on the plug that initiates acne, is now available without a prescription, and has the deepest evidence of any OTC option.
Over-the-counter Benzoyl peroxide
Over-the-counter antibacterial
Generally compatible
Benzoyl peroxide
Over-the-counter antibacterial
A long-standing OTC active available in washes and leave-on products, and a strongly-recommended part of acne care.
At the shelf
Benzoyl peroxide 2.5% to 5%, in a wash if your skin is reactive and a leave-on if it isn't.
Higher strengths are not more effective; 2.5% and 10% perform comparably in comparative trials while the higher figure irritates and bleaches more. Contact time is the real variable, and a wash trades some of it for tolerability.
Watch out for: It bleaches fabric on contact — white towels and pillowcases, and old shirts on the nights you use it.
Browse all benzoyl peroxide products in our catalog →
How it works
Releases oxygen into the pore to kill C. acnes and reduce inflammation. Crucially, bacteria don't develop resistance to it, so it's used to protect antibiotics from resistance when the two are combined.
What the evidence says well established
Benzoyl peroxide carries a strong recommendation in the 2024 AAD acne guidelines, both on its own for mild disease and as a resistance-limiting partner to antibiotics.
Typical course
Once or twice daily; lower strengths (2.5–5%) are as effective as higher ones with less irritation.
Commonly discussed side effects
- Dryness and irritation
- Bleaching of fabrics and hair
- Redness
Worth knowing
- Bleaches towels, pillowcases and clothing — permanently
- 2.5% works as well as 10% and irritates less
- Store it away from heat: benzoyl peroxide degrades into benzene at high temperatures
- Used alongside any antibiotic, it is what limits bacterial resistance
Pregnancy: Benzoyl peroxide is generally considered compatible with pregnancy, but any routine during pregnancy is worth confirming with a clinician.
Why it sits where it does: It appears early and often because it hits the bacterial and inflammatory levers, needs no prescription, and uniquely protects any later antibiotic from resistance.
Over-the-counter Salicylic acid
Over-the-counter exfoliant (BHA)
Generally compatible
Salicylic acid
Over-the-counter exfoliant (BHA)
An oil-soluble beta-hydroxy acid sold in cleansers, toners, and leave-on treatments, most useful for comedonal acne.
At the shelf
Salicylic acid 0.5% to 2% in a leave-on liquid, pad or lotion.
The format matters more than the percentage: a cleanser is on the skin for twenty seconds and off again, which is not long enough for an exfoliant to do much. A leave-on at the same strength is a genuinely different product.
Watch out for: Scrubs and physical exfoliants sold as an equivalent — they work on the surface, and the plug is not on the surface.
Browse all salicylic acid products in our catalog →
How it works
Because it's oil-soluble, it penetrates into the pore and helps clear the plug of oil and dead cells, with mild anti-inflammatory action.
What the evidence says strong
Salicylic acid is an established over-the-counter option for comedonal acne, useful as an adjunct or alternative to a retinoid.
Typical course
Once daily or as a cleanser; gentler than a retinoid, so often better tolerated on sensitive skin.
Commonly discussed side effects
- Mild dryness
- Stinging on sensitive skin
Worth knowing
- Don't layer aggressively with a retinoid and benzoyl peroxide all at once
Pregnancy: Topical salicylic acid in the low concentrations found in OTC products is generally considered acceptable; confirm any routine with a clinician if pregnant.
Why it sits where it does: It's a base-rung comedonal option: needs no prescription, targets the plug, and is gentle enough to combine or to use where a retinoid is too harsh.
Over-the-counter Azelaic acid
Over-the-counter multitasker
Generally compatible
Azelaic acid
Over-the-counter multitasker
A naturally-derived acid available OTC (typically up to 10%) and by prescription at higher strengths, valued for doing several jobs gently.
At the shelf
Azelaic acid 10% in a cream or gel — the usual over-the-counter concentration, against 15–20% on prescription.
The slowest of the four and the most tolerable, which is why it is the usual answer when retinoids and benzoyl peroxide have both proved too harsh. It also works on the brown marks left behind, which none of the others do directly.
Watch out for: Formulas where azelaic acid sits well down the ingredient list behind the marketing — the concentration is what does the work.
Browse all azelaic acid products in our catalog →
How it works
Reduces C. acnes, calms inflammation, and interferes with excess pigment production — which is why it helps both the acne and the marks it leaves.
What the evidence says strong
Azelaic acid is a recognized acne treatment and is particularly useful where post-inflammatory pigment is a concern; it's also well tolerated in sensitive skin.
Typical course
Twice daily; slower to act than benzoyl peroxide but notably gentle.
Commonly discussed side effects
- Mild tingling
- Temporary itch or dryness
Worth knowing
- Give it time — benefits build over weeks
Pregnancy: Azelaic acid is often chosen precisely because it's generally regarded as compatible with pregnancy — but confirm with a clinician for your situation.
Why it sits where it does: It earns an early place for skin that's sensitive or already marking, because it works on bacteria, inflammation, and pigment at once with an unusually forgiving profile.

What changed recently: As of mid-2026, the fixed-dose combination of adapalene 0.1% and benzoyl peroxide 2.5% — long a prescription (Epiduo) — was cleared by the FDA for over-the-counter sale in the US for ages 12 and up, the first prescription retinoid-plus-benzoyl-peroxide combination to make that switch. In practice this raises the OTC ceiling: a combination that used to require a prescription is now something a person can try before ever seeing a clinician.
Prescriptions and procedures
About the brand names below. Brand names are what a pharmacy label says; the generic name underneath is what actually matters, and it's the same molecule whichever box it comes in. Availability shifts as products launch and are discontinued, so treat this as orientation rather than a current stock list. Where a brand is listed for one region and not another, that usually reflects what we could verify — not proof it's unavailable.
The links on these cards go to drug labels and national medicines information — the documents a clinician works from, not a summary of them. They describe the medicine in general; they cannot tell you whether it is right for you, and dosing is a conversation rather than a lookup.

Prescription topical retinoids
Prescription retinoids
The prescription tier of the same retinoid lever available OTC in adapalene — stronger molecules, more formulations, and a clinician's guidance on titrating them.
- Tretinoin — The long-established prescription retinoid, in multiple strengths and formulations.
- Tazarotene — A potent option, often effective where others fall short, but more irritating.
- Trifarotene — A newer retinoid studied for facial and truncal acne.
What it's called at the pharmacy
Generic names Tretinoin · Tazarotene · Trifarotene
Sold as
- Retin-A, Retin-A Micro, Altreno, Atralin, Avita — tretinoin

Renova and Refissa (tretinoin) exist in the US but are approved for wrinkles, not acne — a distinction worth knowing if one is suggested to you.
Read the label
- Tretinoin topical — patient drug information MedlinePlus (US National Library of Medicine)
How it works
Same mechanism as OTC adapalene — normalizing follicular shedding and calming inflammation — at higher potency or in formulations chosen for a given skin type.
What the evidence says well established
Topical retinoids are a strongly-recommended foundation of acne treatment in the 2024 AAD guidelines across comedonal and inflammatory disease.
Typical course
Once daily, usually at night, with a clinician managing the ramp-up to limit irritation. Improvement builds over roughly 12 weeks.
Commonly discussed side effects
- Dryness, peeling, redness
- Early purging
- Sun sensitivity
Worth knowing
- Titration and formulation choice are why this step is clinician-guided
Pregnancy: Topical retinoids, and tazarotene in particular, are avoided in pregnancy. Pregnancy status should be discussed before any prescription retinoid is started.
Why it sits where it does: It's the escalation from OTC retinoid: same lever, greater potency and tailoring, reached when the non-prescription version has had a fair trial without enough result.
Prescription topical Fixed-dose combination topicals
Multi-mechanism prescription topicals
Avoid in pregnancy
Fixed-dose combination topicals
Multi-mechanism prescription topicals
Prescription products that pack two or three mechanisms into one application, reflecting the guideline preference for hitting multiple levers at once.
- Retinoid + benzoyl peroxide — Combines the plug and bacterial levers in one product.
- Retinoid + antibiotic (± benzoyl peroxide) — Adds antibacterial reach; benzoyl peroxide is included to limit antibiotic resistance.
- Triple fixed-dose combination — A single formulation combining a retinoid, an antibiotic, and benzoyl peroxide.

Read the label
- FDA labels for adapalene/benzoyl peroxide products DailyMed (US National Library of Medicine)
How it works
Combine follicular normalization, antibacterial action, and inflammation control depending on the components — with benzoyl peroxide present specifically to protect any antibiotic from resistance.
What the evidence says well established
The 2024 AAD guidelines recommend multimodal topical therapy over single agents. The three-in-one gel's phase 3 trials made the case vividly: about half of participants were clear or almost clear at 12 weeks, roughly double the vehicle arm.
Typical course
Usually once daily; simplifies a regimen by combining actives that would otherwise be layered.
Commonly discussed side effects
- Dryness and irritation
- Bleaching from the benzoyl peroxide component
Worth knowing
- A topical antibiotic is never prescribed alone here — the combination is the point
Pregnancy: Any combination containing a retinoid is avoided in pregnancy; pregnancy-compatible alternatives should be discussed with the prescriber.
Why it sits where it does: It sits just above single topicals because guidelines favor combining mechanisms — more effect, better adherence from fewer products, and built-in resistance protection.
Prescription topical Clascoterone
Topical androgen-receptor inhibitor
Individualized — ask a clinician
Clascoterone
Topical androgen-receptor inhibitor
A first-in-class topical cream (brand name Winlevi) approved in 2020 that blocks the hormonal signal driving oil production — the first topical to work on that lever.
What it's called at the pharmacy
Generic name Clascoterone
Sold as
- Winlevi — approved 2020
- Winlevi — approved
- Winlevi — MHRA approved January 2025; NHS access depends on an ongoing NICE cost-effectiveness assessment

- Winlevi — approved
The newest agent here, so where you live genuinely determines whether it is an option yet.
Read the label
- FDA label for Winlevi (clascoterone) cream 1% DailyMed (US National Library of Medicine)
How it works
Binds androgen receptors in the skin to reduce sebum and inflammation locally, without the systemic hormonal effects of oral options — and it can be used across sexes.
What the evidence says strong
Two identical phase 3 randomized trials found clascoterone 1% cream more effective than vehicle for facial acne, establishing the first topical to target the hormonal driver.
Typical course
Applied twice daily; can be combined with a retinoid since it works on a different lever.
Commonly discussed side effects
- Local dryness or redness
- Uncommon signs of local hormonal effect
Worth knowing
- Newer than the retinoid backbone, so long-term real-world data is still accumulating
Pregnancy: As a newer agent acting on hormonal pathways, its use in pregnancy should be decided individually with a clinician rather than assumed safe or unsafe.
Why it sits where it does: It appears in the inflammatory and hormonal ladders because it reaches a lever no other topical does — the hormonal drive to oil — locally, making it a distinctive add-on rather than a replacement.
Prescription topical Topical dapsone
Anti-inflammatory prescription gel
Individualized — ask a clinician
Topical dapsone
Anti-inflammatory prescription gel
A prescription gel (5% or 7.5%) built on an old oral medicine repurposed as a skin-directed anti-inflammatory — one of the gentlest prescriptions on this page.
What it's called at the pharmacy
Generic name Topical dapsone
Sold as
- Aczone — the original brand
- Widely dispensed as generic dapsone gel
Availability outside the US is patchier than for the retinoid combinations — where it isn't stocked, the tolerability niche is usually filled by azelaic acid.
Read the label
- FDA labels for dapsone gel products DailyMed (US National Library of Medicine)
How it works
Exactly how it calms acne isn't fully worked out; the benefit appears to be mainly anti-inflammatory, quieting the immune response inside lesions rather than attacking the plug or the bacteria head-on.
What the evidence says strong
Large vehicle-controlled trials support once-daily dapsone 7.5% gel for inflammatory acne, with tolerability as its calling card — and the response tends to be strongest in adult women.
Typical course
Once daily at 7.5% (twice daily for the 5% strength), judged over the standard 12-week window like every topical here.
Commonly discussed side effects
- Mild dryness or redness where applied
- A briefly oily or gritty feel with some formulations
Worth knowing
- Applied at the same time as benzoyl peroxide it can temporarily stain skin and fabric orange — use them at opposite ends of the day
- Gentle enough to be worth knowing about when retinoids and benzoyl peroxide have both been too much
Pregnancy: Pregnancy data for the gel is thin, so prescribers weigh it case by case — raise pregnancy or plans for it before starting rather than after.
Why it sits where it does: Its slot in the first-prescription tier is the tolerability pick: inflammation that needs a prescription answer, in skin (or a person) that has had enough of irritation — which is also why it comes up often for adult women and for deeper skin tones, where every inflamed lesion risks leaving a lasting mark.

How it works
They cut down C. acnes in and around the follicle and settle inflammation — overlapping the levers benzoyl peroxide pulls, which is the point of the pairing: benzoyl peroxide's job is to stop the bacteria evolving their way around the antibiotic.
What the evidence says well established
Decades of trials support topical antibiotics against inflammatory acne — and every major guideline now insists they be combined with benzoyl peroxide and kept under review, because resistance made monotherapy obsolete.
Typical course
Once or twice daily alongside benzoyl peroxide, reviewed once control is reached rather than renewed by default.
Commonly discussed side effects
- Dryness and light peeling
- Stinging on application for some
Worth knowing
- Never used alone — without benzoyl peroxide alongside, resistance develops quickly and quietly
- Not layered with an oral antibiotic either: doubling antibiotics adds resistance risk, not results
- Think of it as a course with an end, not a fixture of the routine
Pregnancy: Topical erythromycin and clindamycin are among the few acne prescriptions generally considered usable during pregnancy — part of why they appear in the pregnancy section of this page. Confirm within your own care as always.
Why it sits where it does: It lives inside the first-prescription tier rather than above it because its role is supporting fire — extra reach against bacteria and inflammation while a retinoid deals with the plugs, in a pairing built to leave antibiotic resistance nothing to work with.
Prescription oral Oral antibiotics
Time-limited systemic antibiotics
Avoid in pregnancy
Oral antibiotics
Time-limited systemic antibiotics
A course of oral antibiotic added to topical treatment for moderate inflammatory acne — deliberately time-limited to protect against resistance.
- Doxycycline — The strongly-recommended standard oral antibiotic for acne, with anti-inflammatory as well as antibacterial effect.
- Minocycline — Works as well as doxycycline, but carries rarer-yet-more-serious risks — the main reason doxycycline usually gets the nod.
- Sarecycline — A narrow-spectrum newcomer built to hit C. acnes while sparing more of the gut's resident bacteria.
- Macrolides (erythromycin, azithromycin) — The fallback for people who can't take tetracyclines — including young children and, in short courses, pregnancy.

Reduces C. acnes and, at the doses used for acne, dampens inflammation. Always paired with a topical (including benzoyl peroxide) and never intended as a standalone long-term therapy.
What the evidence says well established
Oral doxycycline carries a strong recommendation in the 2024 AAD guidelines for moderate-to-severe acne, used alongside topical therapy and for a limited duration.
Typical course
Generally a defined course of a few months, always with a topical regimen carrying the result forward when the antibiotic stops.
Commonly discussed side effects
- Stomach upset
- Sun sensitivity (doxycycline)
- Yeast infections
- Rare esophageal irritation if taken without enough water
Monitoring
Reassessment at a set point to stop or step down rather than continue indefinitely.
Worth knowing
- Not a cure — they control acne while taken, and it returns if nothing else is in place
- Time-limited by design: usually no more than three months, and continuing them for many months without clear improvement is not justifiable
- Never doubled up with a topical antibiotic — oral plus topical antibiotic together add resistance risk without adding effect
- Acne is not an infection and cannot be passed to anyone — antibiotics are used here mainly for their anti-inflammatory effect
- Topical treatment continues throughout the course AND after it finishes — that is what stops the acne returning
- Always paired with benzoyl peroxide, which limits the development of resistance
Pregnancy: Oral tetracyclines including doxycycline are avoided in pregnancy and in young children; a clinician selects a pregnancy-appropriate alternative when needed.
Why it sits where it does: Oral antibiotics sit above topical treatment because they reach inflammation that a cream cannot, and below hormonal and isotretinoin options because their role is time-limited by design. The considerations are not only personal: effects on the gut microbiome, and antibiotic resistance in the wider community, are why long courses are increasingly discouraged. Stopping the antibiotic is not the same as stopping treatment — the topical regimen carries on, and is what holds the ground the antibiotic gained.
Prescription oral Hormonal therapy
Systemic hormonal treatment (for those it suits)
Avoid in pregnancy
Hormonal therapy
Systemic hormonal treatment (for those it suits)
Oral treatments that address the hormonal driver of acne rather than its downstream inflammation, suited to hormonal-pattern acne in women.
- Combined oral contraceptives — Certain formulations reduce the hormonal drive to oil and are FDA-approved for acne.
- Spironolactone — Blocks androgen effects; now backed by strong randomized-trial evidence in adult women.
What it's called at the pharmacy
Generic names Combined oral contraceptives · Spironolactone
Sold as
- Aldactone, CaroSpir — spironolactone (CaroSpir is a liquid suspension)
- Ortho Tri-Cyclen, Estrostep Fe, Yaz, Beyaz — the combined pills FDA-approved for acne specifically
- Aldactone — spironolactone
- Dianette — co-cyprindiol (cyproterone acetate + ethinylestradiol)
- Estelle-35, Brenda-35, Juliet-35, Laila-35 — cyproterone + ethinylestradiol, the Diane-35 equivalents
- Diane-35 — cyproterone + ethinylestradiol
Spironolactone is prescribed for acne off-label almost everywhere — it is licensed as a diuretic, not an acne drug, which is normal practice and not a red flag. The cyproterone-containing pills carry a recognised clot risk that regulators have reviewed; it is part of the conversation, not a reason for alarm.
Read the label
- Spironolactone — patient drug information MedlinePlus (US National Library of Medicine)
How it works
Reduce or block the androgen signaling that pushes oil production, cutting the disease off closer to its source for the right patient profile.
What the evidence says well established
Two large randomized trials now anchor spironolactone's place: SAFA found it beat placebo in adult women, and the 2024 FASCE head-to-head found it outperformed doxycycline itself by six months — for this pattern, treating the driver beats borrowing the anti-inflammatory.
- Effectiveness of spironolactone for women with acne vulgaris (SAFA) in England and Wales: pragmatic, multicentre, phase 3, double blind, randomised controlled trial
- Efficacy of spironolactone compared with doxycycline in moderate acne in adult females: results of the multicentre, controlled, randomized, double-blind prospective and parallel Female Acne Spironolactone vs doxyCycline Efficacy (FASCE) Study
Typical course
Taken daily and continued over months; benefits accrue gradually across cycles, so patience is part of the plan.
Commonly discussed side effects
- Spironolactone: lightheadedness, headache, menstrual changes, increased urination
- Combined pills: their own class-specific considerations
Monitoring
A clinician assesses suitability and follow-up individually based on the agent and the person.
Worth knowing
- Suited to specific patient profiles rather than acne in general
- The clock is honest but slow: combined pills show their acne effect over three to six months, spironolactone within a few
- Young, healthy women on spironolactone no longer need routine potassium blood checks — monitoring is reserved for those with kidney or heart conditions or interacting medicines
Pregnancy: Spironolactone is avoided in pregnancy given anti-androgen effects, and combined oral contraceptives are not used during pregnancy. Pregnancy plans are central to choosing hormonal therapy.
Why it sits where it does: It's placed as the systemic option for hormonal-pattern acne because it treats the driver rather than the consequence — the right axis for that presentation, now with strong trial support behind it.
Prescription oral Isotretinoin
Oral retinoid for severe/refractory acne
Avoid in pregnancy
Isotretinoin
Oral retinoid for severe/refractory acne
An oral retinoid (historically known as Accutane) for severe, scarring, or treatment-resistant acne — the most effective acne drug there is, and the one most burdened by myth. Described here as the appropriate treatment it is, not the internet bogeyman it's become.
What it's called at the pharmacy
Generic name Isotretinoin
Sold as
- Absorica, Absorica LD, Amnesteem, Claravis, Myorisan, Zenatane
- Epuris, Clarus, Absorica LD, Accutane Roche
- Roaccutane
- Oratane, Roaccutane
- Roaccutane; Curacne in France
"Accutane" is the name everyone knows, and in the US it hasn't been sold since Roche discontinued it in 2009 — every US prescription today is one of the names above or a generic. If someone offers you Accutane online, that alone tells you what you're dealing with.
Read the label
- Isotretinoin — patient drug information MedlinePlus (US National Library of Medicine)
- Isotretinoin (Roaccutane) — NHS medicines guide NHS (UK)
- The iPLEDGE pregnancy-prevention programme iPLEDGE REMS (US)
- Isotretinoin: new safety measures and the Pregnancy Prevention Programme MHRA / GOV.UK (UK)
How it works
Acts on all four levers at once — shrinking oil glands, normalizing shedding, reducing bacteria, and calming inflammation — which is why it can produce lasting remission where nothing else has worked.
What the evidence says well established
Oral isotretinoin is strongly recommended in the 2024 AAD guidelines for acne that is severe, scarring, causing psychosocial burden, or failing standard oral and topical therapy.
Typical course
A defined course over several months under close specialist supervision, often producing durable remission — with a well-known adjustment period of dryness early on.
Commonly discussed side effects
- Dryness of lips, skin and eyes
- Temporary muscle aches
- Blood lipid and liver changes requiring monitoring
- Mood should be monitored and discussed
Monitoring
Simpler than its reputation: current expert consensus checks a liver enzyme (ALT) and triglycerides at baseline and once more at peak dose — not the monthly full blood panels of the past. The one immovable layer is pregnancy prevention: in the US the iPLEDGE program applies for the whole course, because the drug causes severe birth defects.
Worth knowing
- Requires specialist supervision
- Its reputation outruns its reality for most patients — the conversation is about fit, not fear
- The long-feared link to inflammatory bowel disease has not survived scrutiny: large case-control studies and a 2023 meta-analysis found no increased risk
- About one in five people needs some further acne treatment within two years of a course — that's a known statistic with a plan attached, not a failure
- Most cosmetic procedures no longer wait for the course to end; current guidance defers only dermabrasion and fully ablative laser resurfacing for 6–12 months
Pregnancy: Isotretinoin causes severe birth defects and must never be taken in pregnancy; the US iPLEDGE program enforces pregnancy prevention and testing throughout treatment. This is the single most important fact about the drug. Pregnancy-prevention requirements are handled through a formal programme in every market that licenses the drug, but the programmes differ: iPLEDGE in the US, and a separate Pregnancy Prevention Programme with its own prescriber requirements in the UK.
Why it sits where it does: It sits at the top of the severe branch because it's the one treatment that addresses every driver at once and can end refractory disease — reserved for that level precisely because its monitoring and pregnancy requirements are serious.
Procedure Intralesional corticosteroid
In-office injection
Individualized — ask a clinician
Intralesional corticosteroid
In-office injection
A dilute corticosteroid injected directly into an individual painful nodule or cyst — and, separately, a common first step for raised scars.
How it works
Delivers anti-inflammatory medication straight into a stubborn lesion to shrink it quickly, or flattens a hypertrophic or keloid scar over time.
What the evidence says strong
Intralesional corticosteroid is a standard in-office treatment for individual inflamed nodules and for raised scars, used to rapidly settle a lesion topicals can't reach.
Typical course
A quick in-office injection per lesion, repeatable as needed under clinician judgment.
Commonly discussed side effects
- Temporary skin thinning or a dent at the site
- Lightening of the skin around the injection
Worth knowing
- Operator skill is the main variable in the result — these should only be performed by clinicians specifically trained and experienced in the technique
- A spot treatment for specific lesions, not a treatment for the disease as a whole
Pregnancy: Localized corticosteroid injection is decided case by case in pregnancy; raise pregnancy status with the clinician beforehand.
Why it sits where it does: It's a targeted adjunct within the severe branch and the raised-scar track — it resolves a single problem lesion fast but doesn't replace treating the underlying acne.
Procedure 1726-nm laser (sebaceous-gland laser)
In-office energy device
Individualized — ask a clinician
1726-nm laser (sebaceous-gland laser)
In-office energy device
The newest idea in this list: a laser wavelength absorbed preferentially by skin oil, used to heat and shrink the sebaceous glands themselves. Two devices — AviClear and Accure — were cleared by the FDA in 2022.
How it works
At 1726 nm, sebum absorbs the energy more readily than the surrounding water-rich tissue, so the glands take the heat while contact cooling spares the skin above them. Smaller glands make less oil, and the improvement persists after the sessions end because the target was the gland, not the lesion.
What the evidence says promising
In an open cohort of roughly a hundred patients spanning light to deep skin tones, most had at least halved their inflamed lesions by 12 weeks after three monthly sessions, and results kept improving out to six months. Encouraging and durable — but cohort-level evidence, without the randomized backbone the medicines on this page have.
Typical course
Usually three sessions about a month apart, each 30–45 minutes. Redness, swelling and a short-lived flare can follow a session.
Commonly discussed side effects
- Post-treatment redness and swelling
- A temporary acne flare in some
- Discomfort during the session itself
Worth knowing
- Cash-pay: insurance does not cover it, and a full course runs well into four figures
- Young technology — the durability data so far reaches months, not decades
- Depends on which clinics have invested in the device, so geography is part of the decision
Pregnancy: Elective energy procedures are generally deferred during pregnancy; timing is a conversation with the treating dermatologist rather than a fixed rule.
Why it sits where it does: It closes the escalation tier as the non-drug alternative — a real mechanism aimed at the oil lever no topical reaches, positioned honestly: newer evidence than the drugs beside it, a real price tag, and none of their systemic side effects.
Procedure Laser & energy resurfacing
Fractional laser / energy resurfacing
Individualized — ask a clinician
Laser & energy resurfacing
Fractional laser / energy resurfacing
In-office energy treatments that remodel scarred skin and help even tone — used for atrophic scarring and, gently, for lingering marks, always after the acne is controlled.
- Fractional lasers — Create controlled micro-injury to remodel scar texture over a series.
- Other energy devices — Radiofrequency and light-based devices used for texture and tone.
How it works
Deliver controlled thermal micro-injury that stimulates collagen remodeling, gradually softening depressed scars and refining texture.
What the evidence says strong
Fractional laser resurfacing is an established procedural approach for atrophic acne scars, typically over a series of sessions and best after disease control.
Typical course
A series of sessions spaced weeks apart, with downtime that varies by device intensity.
Commonly discussed side effects
- Redness and swelling after sessions
- Risk of pigment change, higher in richer skin tones and device-dependent
Worth knowing
- Operator skill is the main variable in the result — these should only be performed by clinicians specifically trained and experienced in the technique
- Device choice matters greatly for darker skin
- Only after the acne itself is controlled
Pregnancy: Elective resurfacing is generally deferred during pregnancy; timing is a conversation with the provider.
Why it sits where it does: It's matched to atrophic scarring and stubborn marks in the scar map — a texture-and-tone remodeler that works only once active acne has stopped producing new damage.
Procedure Microneedling
Collagen-induction therapy
Individualized — ask a clinician
Microneedling
Collagen-induction therapy
A procedure using fine needles to create controlled micro-channels that prompt the skin to remodel, used for broad atrophic scarring and texture.
How it works
Micro-injury triggers a wound-healing and collagen response that gradually fills and smooths depressed scars.
What the evidence says promising
Microneedling is a widely-used collagen-induction option for atrophic acne scars, often combined with other modalities over a series of sessions.
Typical course
A series of sessions weeks apart; less downtime than aggressive laser but usually more sessions for a given result.
Commonly discussed side effects
- Redness and pinpoint bleeding on the day
- Temporary swelling
Worth knowing
- Operator skill is the main variable in the result — these should only be performed by clinicians specifically trained and experienced in the technique
- Not performed over active inflammatory acne
Pregnancy: Elective microneedling is typically deferred in pregnancy; confirm timing with the provider.
Why it sits where it does: It sits in the atrophic-scar track as a lower-downtime collagen-remodeling option, frequently paired with subcision or laser for broader texture correction.
Procedure Subcision
In-office scar-release technique
Individualized — ask a clinician
Subcision
In-office scar-release technique
A technique that releases the fibrous tethers pulling a rolling scar down from beneath the surface.
How it works
A fine instrument is passed under the scar to cut the tethering bands, letting the depression lift, often with new collagen forming in the freed space.
What the evidence says strong
Subcision is a well-established technique specifically for tethered rolling atrophic scars, commonly combined with resurfacing or filler.
Typical course
An in-office procedure, sometimes repeated, frequently combined with laser or microneedling.
Commonly discussed side effects
- Bruising and swelling
- Temporary firmness as it heals
Worth knowing
- Operator skill is the main variable in the result — these should only be performed by clinicians specifically trained and experienced in the technique
- Best matched specifically to tethered rolling scars
Pregnancy: As an elective procedure, subcision is generally deferred during pregnancy; discuss timing with the provider.
Why it sits where it does: It's the targeted answer for rolling scars in the scar map because it addresses their specific mechanism — the tether — that surface resurfacing alone can't release.
Procedure TCA CROSS
Focal chemical reconstruction
Individualized — ask a clinician
TCA CROSS
Focal chemical reconstruction
A precise technique applying a high-strength acid to the base of a narrow icepick scar — chemical reconstruction of skin scars (CROSS).
How it works
A focal drop of trichloroacetic acid at the scar's base stimulates localized collagen formation that narrows and lifts the deep, narrow scar.
What the evidence says promising
TCA CROSS is a recognized focal technique for narrow icepick scars, typically over several sessions and reserved for that scar type.
Typical course
Applied point-by-point over several spaced sessions.
Commonly discussed side effects
- Temporary darkening or crusting at each point
- Risk of pigment change
Worth knowing
- Operator skill is the main variable in the result — these should only be performed by clinicians specifically trained and experienced in the technique
- Precision technique specific to icepick scars
Pregnancy: Elective focal acid treatment is generally deferred during pregnancy; timing is a provider conversation.
Why it sits where it does: It's the scar-map match for narrow icepick scars, whose depth and shape make them poor candidates for broad resurfacing but well-suited to focal reconstruction.
On the horizon
Pipeline information current as of 2026-07-16
This section lists only treatments in phase 3 trials or later, or those recently reaching the market. Earlier-stage research is deliberately excluded — early promise often doesn't survive larger trials, and reporting it as if it were around the corner is exactly the hype this site exists to counter.
This changes nothing about what to do now. None of this changes what to do now. A treatment in trials is not a reason to delay care or postpone an effective plan while waiting for it — if your acne warrants treatment today, the pathway above is what's actually available.
Recently arrived
OTC adapalene + benzoyl peroxide combination (2026). The FDA cleared the fixed-dose adapalene 0.1% / benzoyl peroxide 2.5% combination (Epiduo) for over-the-counter US sale in ages 12+ in May 2026 — the first prescription retinoid-plus-benzoyl-peroxide combination to switch to OTC, effectively raising the ceiling of what's available without a prescription.
In late-stage development
DMT310
Phase 3Dermata Therapeutics
A once-weekly topical for moderate-to-severe acne, derived from freshwater sponge, with antimicrobial and anti-inflammatory properties.
Why it's notable: A once-weekly topical would be a meaningful adherence advantage over daily regimens, and its earlier phase 2b results showed a clear separation from placebo.
In the pivotal phase 3 STAR-1 program; enrollment in the first study completed in late 2024, with results to support a potential FDA filing not yet reported as of this writing.
Denifanstat
Phase 3 (US, planned/initiating)Sagimet Biosciences
An oral drug that suppresses sebum production by inhibiting a fat-synthesis enzyme (fatty acid synthase) — a systemic mechanism aimed directly at the oil lever.
Why it's notable: An oral sebum-suppressing option that isn't a hormone or isotretinoin would be a genuinely new category for moderate-to-severe acne; it met its endpoints in a phase 3 trial conducted in China.
A US phase 3 trial was planned to begin in the second half of 2026 following a mid-2026 regulatory filing; not yet available.
Beyond these, a broader set of microbiome-targeted topicals and sebum-suppressing agents is in phase 2 and 3 development — worth watching, but too early to describe as arriving. This section is re-reviewed on its own faster schedule than the rest of the page, because approvals and trial failures land unpredictably.
Things people ask about
Not everything with a following has the evidence to match, and not everything below is useless either. Here's where the popular questions actually stand — so you can spend your patience where it pays.
- Tea tree oil (5%) limited evidence
One small randomized trial found a 5% gel beat placebo over 45 days — slower and weaker than benzoyl peroxide, with irritation of its own. A reasonable curiosity for very mild acne; not a substitute for the actives above.
- Niacinamide gel backed by smaller studies
An older head-to-head found 4% niacinamide gel comparable to a topical antibiotic over eight weeks. As a supporting ingredient it earns its keep; as the whole plan it's underpowered.
- Chemical peels backed by smaller studies
Serial in-office glycolic or salicylic peels can genuinely help clogged-pore acne — as an adjunct. The effect is modest and temporary, and the operator matters as much as the acid.
- Light devices and photodynamic therapy backed by smaller studies
Real effects in studies; unsettled questions about protocol — which light, how long, how often. Something a dermatologist may add, not a foundation to build on.
- Comedone extraction limited evidence
Satisfying, occasionally useful in trained hands, and almost unstudied. What it is not is treatment — nothing about extraction stops the next plug forming.
- Sulfur and sodium sulfacetamide limited evidence
A century of history, a thin modern evidence base. Tolerable fallbacks where standard actives aren't an option, more than contenders in their own right.
- Changing your diet limited evidence
The signals around high-glycaemic eating and dairy are real but not strong enough to prescribe a diet to someone otherwise healthy. The exception: where PCOS or insulin resistance is in the picture, a lower-glycaemic pattern has a legitimate role — alongside standard treatment, never instead of it.
Common questions
How do I know when my acne needs a prescription instead of another product?
The practical test is a fair over-the-counter trial: about 12 weeks of consistent, correct use of proven actives. If your acne hasn't meaningfully improved by then, that's the signal to see a clinician rather than to keep swapping products. Some acne — deep nodules or cysts, anything scarring, or acne causing real distress — warrants a clinician from the start, without waiting out that clock.
Is isotretinoin as dangerous as its reputation suggests?
Its reputation runs well ahead of the reality for most patients. It is the most effective acne treatment there is and is strongly recommended for severe, scarring, or refractory disease, used under close supervision with routine blood monitoring. Its one non-negotiable is pregnancy: it causes severe birth defects and must never be taken in pregnancy, which is why the US iPLEDGE program enforces pregnancy prevention and testing throughout.
Why won't a dermatologist just prescribe an antibiotic to clear it up?
Oral antibiotics do have a role in moderate inflammatory acne, but guidelines deliberately keep them time-limited and always paired with a topical — usually including benzoyl peroxide — to limit antibiotic resistance. A topical antibiotic on its own isn't used at all for the same reason. The aim is to use the antibiotic to gain control, then carry the result forward with treatments that don't drive resistance.
Can I treat my acne scars while I still have active acne?
The standard sequence is to control the acne first, then treat scars. Working on scars while acne is still active means treating a moving target and risking new scars alongside the ones being treated. Once the disease is controlled, the right scar procedure depends on the scar type — tethered rolling scars, broad texture, and narrow icepick scars are each matched to different techniques.
Are there any genuinely new acne treatments coming?
A few are far enough along to mention honestly. The prescription adapalene-plus-benzoyl-peroxide combination became available over-the-counter in the US in 2026, and candidates like a once-weekly topical (DMT310) and an oral sebum-suppressing drug (denifanstat) are in phase 3 development. None of that changes what to do now — if your acne warrants treatment today, waiting for a pipeline drug isn't the move.
I'm pregnant or planning to be — does that change my options?
Substantially, and it's worth raising first. Several first-line acne treatments are avoided in pregnancy — topical and oral retinoids, isotretinoin, spironolactone, and oral tetracyclines among them — while options like azelaic acid and, generally, benzoyl peroxide are more often considered compatible. Because the specifics depend on your situation, pregnancy status is something to state up front so a clinician can build a safe plan around it.
The other 140 questions
Everything that doesn’t fit on a therapy ladder — side effects, timelines, pregnancy, cost, the things people get told that aren’t true. Here are the ones asked most.
- How do I know these bumps are acne and not something else? Real acne produces a mix of lesion types — blackheads, whiteheads, inflamed papules, sometimes cysts. A field of identical bumps is usually something else.
- Why am I getting acne in my thirties when I never had it as a teenager? Adult-onset acne is genuinely common, particularly in women, and it usually arrives as a lower-face and jawline pattern with a stronger hormonal component.
- Is acne caused by not washing enough? No — acne forms inside the follicle from sebum, abnormal shedding and inflammation, which no amount of surface washing reaches, and over-washing actively sets you back.
- Which over-the-counter acne active should I start with? Adapalene for almost everyone, because it works on the plug every lesion begins as. Benzoyl peroxide joins it if you have inflamed spots rather than just bumps.
- Is my skin purging, or is this a reaction? Purging appears where you normally break out, arrives within the first six weeks, and settles. A reaction spreads to new areas, itches or burns, and keeps escalating.
- Is peeling and stinging normal when starting a retinoid? Mild flaking, tightness and brief stinging in the first weeks are expected. Sustained burning, swelling, weeping or redness spreading past where you applied are not.
- Does benzoyl peroxide deactivate my retinoid? It can degrade tretinoin on contact, which is why those two are traditionally separated. Adapalene was designed to be stable with it, so same-application use is fine.
- Does isotretinoin cause depression? Population-level evidence does not show increased risk — a meta-analysis of over 1.6 million patients found no rise in suicide or psychiatric disorders among users.
- Which acne treatments are safe to use in pregnancy? Azelaic acid is the usual first choice, with topical benzoyl peroxide, clindamycin and erythromycin also considered compatible. All retinoids and isotretinoin are out.
- Why does every spot leave a dark mark on my skin? Inflammation triggers melanocytes to deposit extra pigment, and melanin-rich skin responds more strongly. The mark is not a scar and it is not permanent.
- Can I stop treatment once my skin is clear? Clear skin is the treatment working, not the condition ending. Stopping usually means relapse within a few months; maintenance therapy is the standard plan.
- What kind of acne needs to be seen urgently rather than treated at home? Sudden severe ulcerating acne with fever, joint pain or feeling unwell needs same-week medical care. So does any acne that is actively scarring.
- What can a clinic do for acne that products can't? Three things: drain or inject an individual lesion, prescribe drugs that act on sebum production, and treat scarring — none of which any topical can do.
- How do I treat acne and eczema at the same time? Treat the eczema first and stabilise the barrier, then reintroduce acne actives slowly. Inflamed, permeable skin cannot tolerate a retinoid, and forcing it fails both.
- What on a label tells me a product will help? Look for a named active at a stated percentage near the top of the ingredient list. Everything on the front of the pack is marketing until that is present.
