Aestura THERACNE365 Active Serum 30ml Korean BHA AHA zinc acne treatment serum
Strong choice for Acne
What Makes This Different

It stacks three exfoliating acids — salicylic BHA plus lactic and glycolic AHAs — with sebum-regulating zinc salts and a full centella calming complex in one derma-channel serum. Most acne serums pick a single acid; this resurfaces pores and surface texture together while building in the soothing actives that keep the exfoliation tolerable.

Aestura THERACNE365 Active Serum Review

Derm Acne Resurfacer
serum serum pharmacy brand Paraben Free Not Cruelty Free

Aestura's THERACNE365 Active Serum is a genuine multi-acid resurfacer: salicylic BHA, lactic and glycolic AHAs, and sebum-regulating zinc salts, cushioned by a full centella complex. At 35 dollars for 30ml it controls oil and clears congested pores convincingly, with more built-in soothing than most acne serums offer. The acid-plus-alcohol-plus-cooling load means it's firmly for oily, resilient acne-prone skin — dry and sensitive types, and anyone pregnant, should look elsewhere.

Review

Full Review

There's a gap in most acne routines between gentle and effective, and it's where a lot of people get stuck. The drugstore toner does too little; the prescription does plenty but comes with peeling and a doctor's visit. Aestura built the THERACNE365 line to live in that gap — clinic-shelf products with real actives but a derma brand's restraint. The Active Serum is the line's treatment core, and it's an unusually well-stocked one for something you can buy without a prescription.

The headline is that this isn't a single-acid serum. It runs three exfoliating acids at once. Salicylic acid — the oil-soluble BHA — is the lead, getting down inside the pore to dissolve the sebum-and-dead-cell plugs that become blemishes. Backing it are lactic and glycolic acids, water-soluble AHAs that work at the surface, smoothing texture and helping fade the marks blemishes leave behind. A BHA targets the pore; AHAs target the surface; together they resurface on two levels at once. That's a more complete exfoliating strategy than the usual lone salicylic acid, and it's the serum's main point of difference.

The second axis is oil control, and that's where the zinc comes in. Zinc PCA and zinc chloride both appear, salts that help regulate sebum and carry a light antibacterial edge against the microbes implicated in acne. This is why the serum markets itself on excess oil and the look of enlarged pores specifically — it's not just clearing existing breakouts, it's trying to dial back the oiliness that feeds them. Niacinamide high in the formula supports that oil-regulating, mark-fading, barrier-steadying work.

What keeps a serum this active from being punishing is Aestura's signature move: a real calming layer. The full centella triterpene set — asiaticoside, madecassic acid, asiatic acid — plus licorice-derived dipotassium glycyrrhizate sit in the formula to soothe the inflammation that both acne and acid exfoliation generate. It's the same calm-the-actives philosophy that runs through the brand, and it's why users consistently report this is more tolerable than the acid list alone would suggest. The texture helps too: thin, almost watery, fast-absorbing, with a faint cooling sensation and a matte-leaning finish that oily skin appreciates.

Now the honest part, because this serum demands respect. The same things that make it effective make it potentially irritating: a BHA, two AHAs, alcohol denat fairly high on the list, and menthoxypropanediol for that cooling tingle. That's a meaningful load, and it firmly defines the audience. Oily and resilient acne-prone skin will get along with it; dry and sensitive skin will likely find it too much, which is why it earns a caution there rather than a recommendation. It is a pregnancy no, given the salicylic and other acids. And the discipline matters more than with a gentle serum — once nightly is the ceiling, starting a few nights a week and buffering with moisturizer, because doubling up doesn't clear skin faster, it strips the barrier and can backfire into more breakouts. A mild cool tingle is normal; persistent burning or peeling is the signal to pull back.

It's worth separating the two kinds of work the acids do, because they explain who benefits most. The salicylic acid is the targeted actor — oil-soluble, it dives into the pore and works on the comedonal plugs that become blackheads and whiteheads, which is why congested, blackhead-prone skin tends to see the clearest results. The AHAs work on the flat surface, refining texture and dullness, so the secondary payoff is smoother, brighter-looking skin overall. If your main concern is clogged pores and bumps, the BHA is doing your heavy lifting; if it's roughness and uneven texture, the AHAs are.

There's also a sequencing logic to where this sits in a routine, and getting it right is half the battle. Because it's a leave-on multi-acid, it belongs on its own at the treatment step, not buried under or over other actives that would compound the irritation. The smartest pattern for most people is to alternate it with a retinoid on separate nights rather than stacking them, and to keep the in-between nights purely soothing and hydrating so the barrier recovers. Used that way, the centella buffer in the formula has room to do its job, and the serum delivers its resurfacing without the over-exfoliation spiral that sinks so many acne routines.

The value picture is fair but not generous: 35 dollars for 30ml is standard for the derma-serum tier but a small bottle, and at nightly use it's a six-to-eight-week supply. For the right user — oily, acne-prone, looking for a step up from basic care without going prescription, and willing to use it with discipline — it's a smartly built, genuinely effective option with reassuring clinical pedigree. For dry, sensitive, or pregnant users, or anyone wanting a gentle daily serum, this is the wrong tool, and a calming or azelaic-based product is the better path. Judged as the active middle ground it sets out to be, the THERACNE365 serum delivers.

Formula

Key Ingredients

The hero actives that drive this product's performance.

IngredientFunctionEvidence
Salicylic Acid (BHA) The oil-soluble exfoliant that gets inside the pore to clear the sebum and dead-cell plugs behind blemishes. It is the serum's primary acne actor, working with the dual AHAs below it to resurface, while the centella and licorice further down keep the exfoliation from tipping into irritation. Regulator-approved for Acne · emerging certainty
Lactic Acid + Glycolic Acid (AHAs) A surface-level AHA pair that complements the BHA's pore work by smoothing texture and helping fade post-blemish marks. Their inclusion alongside salicylic acid makes this a multi-acid resurfacer rather than a single-exfoliant serum, broadening the action across pores and surface tone. Not yet assessed
Zinc PCA + Zinc Chloride The oil-and-shine regulators of the formula, zinc salts that help curb sebum and add a light antibacterial edge against acne-driving microbes. They are why this serum targets excess oil and enlarged-looking pores specifically, not just existing breakouts. Limited for Acne
Niacinamide High at position 5, supporting the barrier and helping fade marks while also contributing to oil regulation. In an acid-and-zinc acne serum it is the steadying multitasker that keeps the resurfacing from leaving skin raw and uneven. Limited for Acne
Centella Complex (Asiaticoside, Madecassic Acid, Asiatic Acid) The calming counterweight, a full centella triterpene set plus licorice-derived dipotassium glycyrrhizate, included to soothe the inflammation that both acne and acid exfoliation produce. It is the reason a fairly active serum stays usable on sensitized acne-prone skin. Not yet assessed

Evidence

Science & Expert Perspective

The Science

The serum's resurfacing claim is well supported by its acid trio. Salicylic acid is a lipophilic beta-hydroxy acid with strong evidence for penetrating sebaceous pores and clearing comedonal acne, while glycolic and lactic acids are alpha-hydroxy acids documented to exfoliate the surface, smooth texture, and improve post-inflammatory marks. Using a BHA with AHAs targets both follicular and surface exfoliation, a rational combined approach. The zinc salts (zinc PCA, zinc chloride) have data supporting sebum regulation and modest antimicrobial activity relevant to acne, and niacinamide adds barrier support, sebum modulation, and mark-fading. The calming counterweights are equally evidenced: centella triterpenes (asiaticoside, madecassic and asiatic acids) reduce inflammation and support healing, and dipotassium glycyrrhizate is an anti-inflammatory licorice derivative. The trade-off is irritation potential: the combined acids plus alcohol denat and the cooling agent menthoxypropanediol raise the sensitization risk, which is why frequency control and barrier support are essential. Mechanistically the formula is coherent — multi-acid exfoliation and zinc oil control, deliberately buffered with anti-inflammatory actives — but it sits firmly on the active end of over-the-counter acne care.

Dermatologist Perspective

Combining a beta-hydroxy acid with alpha-hydroxy acids and zinc reflects a recognized approach to comedonal and oily acne, addressing both follicular plugging and surface texture, and the centella-and-licorice calming layer aligns with advice to buffer exfoliating actives. Clinical guidance would frame this as a moderately active over-the-counter treatment best suited to oily, resilient acne-prone skin, with cautious introduction — a few nights weekly, built up gradually, paired with a barrier-supporting moisturizer and daily sun protection, since exfoliating acids increase photosensitivity. Dry, sensitive, or barrier-compromised skin is more likely to react, and the acids make it unsuitable during pregnancy. For inflammatory or cystic acne it would typically serve as an adjunct rather than a standalone treatment, with persistent or severe acne warranting professional evaluation.

Guidance

Usage & Recommendations

How to Use

Use at night. After cleansing and toner, apply a thin layer of serum to dry skin, avoiding the eye area, then follow with a soothing moisturizer to buffer the acids. Start two to three nights a week and build to nightly only as your skin tolerates it. Avoid layering it the same night with retinoids, vitamin C, or other strong acids. Always apply broad-spectrum SPF the next morning, since the exfoliating acids increase sun sensitivity, and cut back frequency if you notice persistent stinging or dryness.

Value Assessment

At 35 dollars for 30ml, the serum is priced in line with the Korean derma-treatment tier but is a small bottle, lasting roughly six to eight weeks at nightly use. There is a single size, so no bulk option softens the cost. The value is reasonable for someone who specifically needs a multi-acid-plus-zinc treatment with built-in soothing and clinical pedigree, and who will use it with discipline; that buyer is paying for a considered formulation, not just one cheap acid. For someone who only wants a basic salicylic acid exfoliant, lower-cost single-acid serums deliver that more economically, but they won't match this serum's combined resurfacing-and-oil-control approach or its centella buffer.

Who Should Buy

Oily and combination, acne-prone skin wanting a step up from basic care without a prescription. Those dealing with excess oil, congested or enlarged-looking pores, and comedonal breakouts who can tolerate active exfoliation. Anyone who values a dermatologist-channel brand with real acids buffered by a genuine calming complex.

Who Should Skip

Dry, sensitive, or barrier-compromised skin will likely find the acid-alcohol-cooling load too harsh. Anyone pregnant or breastfeeding should avoid the salicylic and AHA content. Those with inflammatory or cystic acne needing real medical treatment, or anyone wanting a gentle daily serum, should look to a calming or azelaic-based alternative.

Background

The Story Behind This Product

Aestura developed the THERACNE365 line for Korea's clinic shelves, where acne patients needed something more active than a basic toner but gentler than a prescription. The Active Serum is the range's treatment core, designed to deliver real multi-acid and zinc oil control with Amorepacific's signature centella-and-licorice soothing layer baked in.

About Aestura Established Brand (5–20 years)

Aestura is Amorepacific's clinic-channel dermocosmetic brand, established in 2011 and a fixture in Korean dermatology offices. The THERACNE365 line is its dedicated acne-care range; this Active Serum is the line's treatment step, combining BHA, dual AHAs, and zinc with centella, reflecting Amorepacific's R&D approach of pairing real exfoliating actives with calming support rather than relying on a single harsh ingredient.

Myth vs. Reality

Common Myths

Myth

More acids means faster clear skin, so use it twice a day.

Reality

This serum carries a BHA and two AHAs plus alcohol and a cooling agent — a meaningful exfoliating load. Using it once nightly, building up gradually, and buffering with moisturizer clears skin more reliably than daily overuse, which strips the barrier and can worsen breakouts.

FAQ

Frequently Asked Questions

What acids are in the Aestura THERACNE365 Active Serum?

It combines salicylic acid (a BHA that exfoliates inside pores) with lactic and glycolic acids (AHAs that smooth surface texture and fade marks). That multi-acid blend is paired with zinc salts for oil control, making it a resurfacing acne serum rather than a single-acid exfoliant.

Is the THERACNE365 Active Serum good for oily skin?

Yes — it is built for oily and acne-prone skin specifically. The salicylic acid clears pores, the zinc PCA and zinc chloride curb sebum and shine, and the multi-acid action refines the look of enlarged pores. Drier and sensitive skin should approach it more cautiously.

How often should I use this Aestura acne serum?

Start a few nights a week and build up as tolerated, using it as your PM treatment step before moisturizer. With a BHA, two AHAs, alcohol, and a cooling agent, once nightly is the ceiling for most skin; overuse strips the barrier rather than clearing faster.

Can I use this serum while pregnant?

Best avoided — it contains salicylic acid and other exfoliating acids that are commonly limited during pregnancy. Choose a gentler azelaic acid or centella-based option instead and confirm any acne routine with your provider.

Does it sting, and is that normal?

A mild cooling tingle on application is expected from the menthoxypropanediol and acids. A brief, light sting can be normal as skin adjusts, but persistent burning, redness, or peeling means you are overusing it — cut back frequency and buffer with moisturizer.
