How it works
An acid toner here does two jobs at once: the surface, and the debris inside a pore, which are different problems and usually two products. This is the clarifying toner in COSRX's line, a thin liquid that goes on with a cotton pad after cleansing, in place of the toner step. It suits skin that reads rough across the forehead and congested around the nose. On the evenings it is used, nothing else exfoliating belongs in the routine, and moisturizer follows once it has settled. Sunscreen the next morning is part of using an acid at all.
Key benefits
- Glycolic acid (AHA) and betaine salicylate (BHA) sit back to back at entries seven and eight, one formula covering surface texture and pore congestion
- Allantoin and panthenol close an eleven-ingredient list, the shortest way to cushion two acids in one step
- Willow bark water and apple fruit water lead the base ahead of plain water
- COSRX runs its own brand-portal verification: enter the batch number and expiry from your unit on cosrx.com
- No fragrance, no parfum, no essential oil on the list
- Sourced for the Korean market, Korean barcode 8809416470030 intact on the box
Inside the formula
Inside the formula
COSRX AHA/BHA Clarifying Treatment Toner
What is the AHA/BHA Clarifying Treatment Toner for?
This 150 ml toner opens with water plus willow bark water and apple fruit water, then glycolic acid and betaine salicylate sit back to back further down an eleven ingredient list. That pairing puts an AHA and a BHA style ingredient in the same short formula, aimed at surface texture and clogged pores together. Allantoin and panthenol follow immediately after to keep the pass over skin comfortable.
Is this toner suitable for sensitive or first time acid users?
There is no fragrance, essential oil, denatured alcohol, or added colourant on this eleven ingredient list, and allantoin and panthenol sit right behind the two acids for comfort. Because glycolic acid and betaine salicylate are both present in the same short formula, first time acid users or anyone with a compromised barrier should start with a few uses a week rather than daily. Anyone new to exfoliating acids should patch test before regular use.
How does this toner behave with continued use?
Glycolic acid and betaine salicylate need repeated use to show a change in surface texture and pore appearance; a single swipe will not visibly resurface skin. Some tingling on first use is common with an AHA and BHA combination and typically settles as skin builds tolerance over several weeks. If redness or flaking persists rather than easing, cutting back frequency before stopping is the reasonable move.
Can I layer this with a retinoid or a tone-evening serum?
There is no retinoid and no niacinamide on this eleven ingredient list, so both can be layered into the same routine as separate steps. Because this toner already carries two active acids, stacking a retinoid in the same session can add up to more exfoliation than skin needs at once, so many routines keep this toner to one part of the day and a retinoid to the other. Introduce any new step slowly and watch how skin responds.
How can I tell my AHA/BHA Clarifying Treatment Toner is the real Korean market COSRX formula?
The 13 digit barcode on the carton, 8809416470030, is a real, valid Korean market code you can compare against COSRX's own records. COSRX also runs its own brand portal verification on cosrx.com, where you enter the batch number and expiration date from your unit rather than trusting a number we print. We source and list this as authentic Korean market COSRX stock, with the Hangul ingredient panel under our English over label as the physical record.

Ingredient list read from incidecoder.com on 9 September 2026.
11 of 11 explained
- Water solvent
- Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
- Salix Alba (Willow) Bark Water plant extract
- Willow bark distillate. It is much more dilute than willow bark extract and carries little of the salicin the extract is used for.
- Pyrus Malus (Apple) Fruit Water plant extract
- Apple distillate used in place of plain water. Like every fruit water it is far more dilute than the extract of the same fruit.
- Butylene Glycol humectant
- Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
- 1,2-Hexanediol humectant
- 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
- Sodium Lactate humectant
- Sodium Lactate is the salt of lactic acid and one of the components of skin's own natural moisturising factor. At the levels used here it is a humectant and buffer rather than an exfoliant.
- Glycolic Acid exfoliant
- Glycolic Acid is the smallest AHA, which is why it is also the most penetrating and the most likely to sting. It loosens the bonds between dead surface cells and is used for the look of dullness and rough texture.
- Betaine Salicylate exfoliant
- Betaine Salicylate is a gentler salicylic derivative. Korean formulas use it at around 2 to 4 percent, which is roughly comparable to a low-strength salicylic acid, and it is easier on the skin barrier.
- Allantoin active
- Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.
- Panthenol humectant
- Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
- Ethyl Hexanediol humectant
- Ethyl Hexanediol is a glycol that hydrates and makes a formula less hospitable to microbes, the same double role 1,2-hexanediol plays.

How to use
- Use the AHA BHA Clarifying Treatment Toner after cleansing, in place of your toner step, in the evening.
- Sweep it over dry skin with a cotton pad, keeping clear of the eyelids and the corners of the mouth.
- Wait a minute, then carry on with serum and moisturizer the same evening.
- Start at two or three evenings a week. Do not pair it with another acid or a retinoid in the same routine.
Worth knowing
- This formula carries an active acid, so pairing it with another exfoliant in the same routine is worth spacing out.
