It's a leave-on acne toner that calms as much as it clarifies — niacinamide for evidenced oil-and-tone benefits, willow bark for gentle pore support, and a deep five-cica soothing stack plus a repair peptide, all fragrance-free and fungal-acne-safe. Because the actives stay on the skin, it does treatment work the brand's rinse-off acne cleanser can't.
The leave-on partner to the brand's gentle acne cleanser, and arguably the more useful of the two: niacinamide does real oil-and-tone work, willow bark adds soft pore support, and a deep five-cica stack calms breakout inflammation — all fragrance-free and fungal-acne-safe. Because the actives stay on the skin, it earns its place in an acne routine. Just don't expect strong exfoliation; it calms and balances rather than peels.

The studies behind the evidence row

There's a quiet logic to how skincare actives deliver their benefits, and it comes down to contact time. A cleanser, no matter how thoughtfully formulated, rinses off in under a minute — its anti-inflammatory herbs and pore-clearing ingredients get a brief handshake with your skin and then go down the drain. A leave-on toner, by contrast, stays put for hours, giving the same actives the time they actually need to work. That's why this ACNE Toner, the leave-on companion to Pyunkang Yul's popular ACNE Facial Cleanser, is in some ways the more consequential product of the pair: it's where the line's acne ingredients finally get to stick around and do something.
And the most important thing it adds, beyond contact time, is niacinamide. The cleanser leaned on willow bark and botanicals; this toner keeps those but slots niacinamide in high on the list, just below the willow bark. That matters because niacinamide is genuinely well-evidenced for acne-prone skin — it regulates sebum, calms redness, supports the barrier, and helps with tone — and as a leave-on it has the staying power to actually deliver those benefits. If the cleanser's acne credentials were mostly aspirational (mild ingredients, briefly applied), the toner's are real, and niacinamide is the reason.
The willow bark carries over, and the honest framing is the same as for the cleanser: it's a natural source of salicin, a gentle, BHA-adjacent ingredient that offers soft pore support, not the punch of a dedicated salicylic acid treatment. The difference here is that, left on the skin, it at least gets the contact time to contribute meaningfully to oil control. But it's the niacinamide, not the willow bark, that's the workhorse — if you're hoping for strong exfoliation, you'll still want to layer a proper BHA, and use this for what it actually does well.
What it does well, beyond balancing oil, is calm. The toner carries the brand's deep soothing stack — the 'five cica' marketing refers to centella plus forsythia, Scutellaria, licorice, chamomile, and more, traditional anti-inflammatory herbs from the parent hospital's heritage — and on leave-on skin these work to quiet the inflammation that makes acne red, sore, and angry. There's niacinamide reinforcing the anti-redness effect, copper tripeptide-1 supporting repair of blemish-damaged skin, and myrtle and nasturtium extracts rounding out the botanical roster. For acne-prone skin that's as irritated as it is congested — which is most acne-prone skin — that calming emphasis is genuinely valuable.
In use, it's the easy, pleasant step you'd expect. The texture is thin and watery, absorbing the instant you pat it on, leaving skin lightly hydrated, calm, and never tight or stinging. It's fragrance-free and essential-oil-free (a small amount of rosemary extract is the only mild flag for the very reactive), oil-free, and fungal-acne-safe, so it suits sensitive and malassezia-prone skin too. Slot it in after the ACNE Facial Cleanser and before your serums and moisturizer, and the two form a coherent, gentle, calming acne-care base. The payoff builds over three to six weeks: better-balanced oil, calmer redness, and skin that's less reactive overall.
The limitations echo the cleanser's, softened by the niacinamide. This is still a gentle, supportive product, not a standalone acne cure — moderate-to-severe acne needs proven treatments doing the heavy lifting, and this toner is the calming, oil-balancing, hydrating layer around them. The willow bark won't satisfy anyone wanting strong exfoliation, and people expecting a dramatic, active-feeling toner may find it quietly understated. But understated and effective is exactly the brief for acne-prone skin, where drama usually means irritation.
The value is strong, consistent with the line. At around $18 for 150ml, lasting two to three months, it's an affordable way to add a genuinely useful leave-on niacinamide-and-soothing step to an acne routine, undercutting many comparable treatment toners. Paired with the equally cheap cleanser, you can build a gentle acne-cleansing foundation for under thirty dollars.
A note on building it into a routine sensibly: because the niacinamide here is the real workhorse, this toner pairs especially well with a separate, stronger treatment rather than duplicating it. Use the toner as your everyday calming, oil-balancing leave-on base, and reserve a dedicated BHA or a prescribed active for the targeted clearing work, ideally on alternating days or at a different time so you're not stacking irritation. The toner's gentleness is precisely what lets it coexist with stronger products without tipping skin into over-treatment — it calms the background noise of inflammation while the heavy hitters tackle the congestion, which is a smarter division of labor than asking any one gentle product to do everything.
Where it lands: this is a quietly excellent treatment toner for acne-prone and sensitive-acne skin, and if you're choosing between it and the matching cleanser, the toner gives you more — niacinamide and leave-on contact time make it the one doing real work. Buy it understanding its role as the calming, oil-balancing layer of a fuller routine rather than a strong exfoliating treatment, pair it with proven actives for the actual clearing, and it earns its keep. Gentle, evidenced, fungal-acne-safe, and cheap is a combination acne-prone skin rarely gets, and this delivers it.
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Willow Bark Extract | A natural salicin source placed high in the formula to help control sebum and gently support clearer pores — and because this is a leave-on toner rather than a rinse-off cleanser, the willow bark has real contact time to do its mild pore-clearing work. | Not yet assessed |
| Niacinamide | The toner's most evidence-backed active, sitting just below the willow bark to regulate oil, calm redness, and support the barrier — its addition is what gives this leave-on toner genuine acne-and-tone benefits the rinse-off cleanser can't deliver. | Limited for Acne |
| Five-Cica Anti-Inflammatory Complex (Centella, Forsythia, Scutellaria, Licorice, Chamomile) | A deep stack of soothing, anti-redness herbs that calm the inflammation driving breakouts — left on the skin, they work to reduce the angry, sore quality of acne, making this a treatment toner that calms as much as it clarifies. | Not applicable for Sensitivity |
| Copper Tripeptide-1 | A skin-repair peptide carried over from the cleanser but far more useful here as a leave-on — it supports healing of blemish-damaged skin over time, reinforcing the line's repair-and-calm approach to acne. | Not yet assessed |

Sweep or pat onto clean skin after cleansing and before serums and moisturizer. It pairs naturally with the brand's ACNE Facial Cleanser beneath your treatments, and its leave-on niacinamide and willow bark work best applied to slightly damp skin.
Calm, hydrated, non-tight skin is immediate. The niacinamide and willow bark build oil-balancing, breakout-calming benefits over three to six weeks of consistent daily use, with the anti-inflammatory herbs soothing redness throughout.
As a leave-on toner, this formula's actives have meaningful contact time, which strengthens its case relative to the matching rinse-off cleanser. The standout is niacinamide, placed high in the formula: niacinamide has robust evidence for sebum regulation, anti-inflammatory effects relevant to acne, barrier support via increased ceramide synthesis, and tone-evening — making it the toner's most defensible active. Willow bark (Salix alba) extract provides salicin, a salicylic acid precursor; left on the skin it has more opportunity to contribute than in a cleanser, but its delivered exfoliating activity at cosmetic concentrations remains mild and less established than synthetic salicylic acid, so its role is gentle pore and sebum support. The anti-inflammatory botanical stack — centella (triterpenoids), Scutellaria (baicalin), licorice (licochalcone/glabridin), forsythia, chamomile, green tea (EGCG), myrtle, and nasturtium — has promising evidence for soothing and anti-inflammatory activity relevant to inflammatory acne, and as leave-on ingredients they can act more fully than in a wash-off product. Copper tripeptide-1 has promising skin-repair and wound-healing evidence, more useful here as a leave-on. Dimethyl sulfone (MSM) and pyridoxine (B6) provide minor supportive roles. The fragrance-free, oil-free, alcohol-free base is low-irritation and fungal-acne-safe. The honest reading: a well-formulated calming-and-oil-balancing leave-on toner whose niacinamide provides genuine evidenced benefit, with willow bark contributing gentle rather than potent exfoliation.
Clinically, a leave-on toner like this is a more meaningful contributor to an acne routine than a rinse-off cleanser, because its actives remain on the skin. Niacinamide is a well-supported ingredient for acne-prone skin — useful for oil regulation, inflammation, and barrier support — and its prominent inclusion here is the formula's strongest clinical feature. The anti-inflammatory botanical content aligns with the increasingly recognized importance of calming inflammation in acne management, and the fragrance-free, oil-free, fungal-acne-safe formulation suits sensitive and malassezia-prone skin. As with the cleanser, willow bark should be understood as a mild ingredient rather than a substitute for proven exfoliating actives. Patients with significant acne should view this as the soothing, oil-balancing layer of a regimen that also includes evidence-based treatments such as topical retinoids, benzoyl peroxide, or salicylic acid, with daytime sun protection. For gentle, barrier-friendly, niacinamide-containing toning of acne-prone skin, it is a sensible, well-considered choice.
After cleansing, pat or sweep the toner onto slightly damp skin, morning and night, before your serums and moisturizer. Applying to damp skin helps the niacinamide and willow bark absorb. It layers cleanly under acne treatments and lightweight moisturizers, and pairs naturally with the brand's ACNE Facial Cleanser. Use it consistently twice daily to build the oil-balancing and calming benefits, and add a dedicated BHA elsewhere in your routine if you need stronger exfoliation. In the morning, finish with non-comedogenic sunscreen, and patch test first if your skin reacts to rosemary or other botanicals.
This toner offers strong value for a leave-on acne treatment step. At around $18 for 150ml, lasting two to three months of twice-daily use, the per-use cost is low, and it undercuts many comparable niacinamide-and-soothing treatment toners. The inclusion of niacinamide, a deep anti-inflammatory botanical stack, and a repair peptide is more than most budget toners offer. Paired with the brand's similarly affordable ACNE Facial Cleanser, it allows a gentle acne-cleansing-and-toning foundation for well under thirty dollars. The value is best for acne-prone and sensitive skin wanting a calming, oil-balancing leave-on layer; those needing strong exfoliation will add a separate BHA, but the toner itself is a genuine bargain and arguably the better-value half of the cleanser-and-toner pair.
Acne-prone, oily, combination, and sensitive-acne skin wanting a gentle leave-on toner that balances oil and calms breakouts with niacinamide and soothing herbs. It's a great fungal-acne-safe, fragrance-free, affordable treatment step, and the ideal partner to the brand's ACNE Facial Cleanser.
Moderate-to-severe acne expecting a toner to clear it alone should pair it with stronger treatments, since the willow bark is mild. Anyone wanting a potent exfoliating toner or dramatic, active-feeling results will find it too gentle and understated.
A thin, watery toner that absorbs instantly with a light, slightly hydrating finish and no tack.
Fragrance-free and essential-oil-free, with only a faint natural note from the botanical extracts.
A 150ml bottle with a standard pour opening; simple and practical, consistent with the brand's minimalist look.
The watery toner absorbs the moment you pat it on, leaving skin lightly hydrated, calm, and never tight or stinging. There's no fragrance and no adjustment period. Acne-prone skin feels immediately soothed; the oil-balancing and breakout-calming benefits build over several weeks of consistent daily use.
The 150ml bottle lasts roughly 2-3 months applied morning and evening, depending on how generously it's applied.
All Year
Built as the leave-on companion to the ACNE Facial Cleanser, this toner carries the same hospital-derived, calming-first philosophy into a step where actives have time to work. The brand added niacinamide to the shared botanical base, turning a soothing toner into one that genuinely supports oil balance and clearer skin for breakout-prone users.
Pyunkang Yul was founded in 2016 by Korea's Pyunkang Korean Medicine Hospital, lending its formulas derm-adjacent, herbal-medicine credibility. This toner is the leave-on companion to its ACNE Facial Cleanser, pairing willow bark and niacinamide with a deep botanical soothing stack, and has a large, positive review base among acne-prone users.
A toner is just an unnecessary extra step that doesn't do anything.
This isn't a stripping, alcohol-based 'old-school' toner — it's a leave-on treatment toner with niacinamide, willow bark, and soothing actives that stay on the skin to balance oil and calm breakouts. As a hydrating, barrier-friendly layer in an acne routine, it does real, if gentle, work.
The willow bark makes this a strong exfoliating acne toner.
Willow bark is a mild, natural salicin source, not a potent BHA — it offers gentle pore support, but the toner's real workhorse is the niacinamide. For stronger exfoliation, layer a dedicated BHA; this toner's job is to calm, hydrate, and gently balance.
As a leave-on treatment toner, it balances oil and gently supports clearer pores through niacinamide and willow bark, while a deep stack of soothing herbs (centella, licorice, forsythia, chamomile) calms the inflammation behind breakouts. Unlike a rinse-off cleanser, its actives stay on the skin to work, so it offers real, if gentle, oil-balancing and calming benefits over a few weeks.
Willow bark is a mild, natural source of salicin rather than a potent BHA, so it offers gentle pore support, not strong chemical exfoliation. The toner's most evidence-backed active is actually the niacinamide. If you need real exfoliation, layer a dedicated salicylic acid product; use this toner for its calming, oil-balancing, hydrating benefits.
Yes — they're designed as a pair. Cleanse with the ACNE Facial Cleanser, then pat this toner onto clean skin before your serums and moisturizer. Together they form a gentle, calming acne-care foundation, with the toner adding leave-on niacinamide and willow bark that the rinse-off cleanser can't deliver.
Yes — it's fragrance-free, alcohol-free, oil-free, and built on a deep soothing botanical stack, so it hydrates and calms without stinging or stripping. It's well-suited to sensitive, reactive, acne-prone skin. The only mild flag is a small amount of rosemary extract, so the very reactive may want to patch test first.
Yes — it's oil-free, fragrance-free, and free of the esters and oils that feed malassezia, making it a safe leave-on option for those managing fungal acne alongside regular acne. Its niacinamide and soothing actives suit both concerns without aggravating malassezia-driven breakouts.
Yes — it uses willow bark and gentle botanicals rather than retinoids or high-strength salicylic acid, plus niacinamide, and is fragrance-free. The trace salicin from willow bark is minimal. As always, confirm any acne routine with your OB or dermatologist during pregnancy if you have concerns.
