COSRX AHA/BHA Clarifying Treatment Toner (150ml)

Clearer, smoother skin doesn't have to come at the cost of your moisture barrier. This gentle dual-acid toner combines the surface-refining power of AHA with the pore-clearing action of BHA, both sourced from natural botanicals, to dissolve dead skin buildup, decongest pores, and reveal visibly brighter skin. Lightweight, hydrating, and completely free from fragrance and alcohol, it's chemical exfoliation done the right way.

This toner is made for you if:

• Your pores stay clogged no matter how well you cleanse, or you deal with recurring blackheads, whiteheads, or congestion.
• You've tried exfoliants before and found them too harsh, drying, or irritating.
• You're new to chemical exfoliation and want a gentle, beginner-friendly entry point that actually delivers results.

Key Features

• Dual-Acid Exfoliation System _ Combines AHA (glycolic acid + apple fruit water) and BHA (betaine salicylate + willow bark water) for surface-level smoothing and deep pore-clearing action in a single step.
• Hydrating Mineral Water Base _ Formulated with mineral water, sodium lactate, panthenol, and allantoin to maintain moisture levels and soothe the skin barrier throughout exfoliation.
• Lightweight, Non-Disruptive Texture _ A refreshing liquid formula that preps skin perfectly for serums and moisturizers without throwing off your pH balance.
• Fragrance-Free & Alcohol-Free _ No harsh additives, no unnecessary irritants, just a clean, carefully calibrated formula built for sensitive and reactive skin too.
• Beginner-Friendly Strength _ Gentle enough for those new to chemical exfoliation while still delivering consistent, visible results for more experienced users.

Why You'll Love It

• Smoother Texture, Less Dullness _ Dual acids work in sync to dissolve dead skin cells and resurface the complexion, revealing brighter, softer skin with regular use.
• Visibly Clearer Pores _ BHA penetrates deep into pores to break down sebum and dead skin buildup, reducing blackheads, whiteheads, and persistent congestion over time.
• Exfoliates Without the Fallout _ Balanced acid concentrations paired with hydrating actives mean no tightness, no dryness, and no over-stripped skin after use.
• Fits Your Schedule _ Flexible enough to use daily for resilient skin or every other day for more sensitive types, you set the pace.
• Fades Post-Acne Marks _ Glycolic acid's surface-refining action helps gradually even out skin tone and reduce the visibility of dark spots left behind by breakouts.

Star Ingredients

• Apple Fruit Water (AHA Source) _ Delivers natural glycolic acid for mild surface exfoliation, enhanced radiance, and smoother skin texture with every use.
• Willow Bark Water (BHA Source) _ A natural salicylic acid source that works oil-solubly to penetrate pores, clear impurities, and reduce breakouts at their root.
• Glycolic Acid _ The smallest-molecule AHA available, refining skin's surface, fading post-acne marks, and improving overall tone and texture effectively.
• Betaine Salicylate _ A gentler, naturally derived BHA that clears pores and exfoliates without the dryness or irritation of traditional salicylic acid.
• Panthenol & Allantoin _ Calming, barrier-supporting agents that soothe and protect skin during and after exfoliation, reducing sensitivity and supporting regeneration.
• Mineral Water _ Hydrates, refreshes, and helps maintain optimal pH balance and electrolyte equilibrium throughout the formula.

Good to Know Before You Buy

• Best For _ Oily, combination, and acne-prone skin. Many sensitive skin types tolerate it well, but patch testing before full use is strongly recommended.
• Sunscreen Is Non-Negotiable _ Chemical exfoliants increase UV sensitivity. Always follow with SPF 30 or higher during the day, every day.
• Don't Stack Acids _ Avoid using alongside other AHAs, BHAs, retinol, or vitamin C on the same day to prevent over-exfoliation and barrier damage.
• Ease Into It _ If any redness or irritation occurs, reduce to every other day or 2–3 times per week until your skin adjusts.
• Pregnancy & Breastfeeding _ Consult your healthcare provider before using chemical exfoliants during pregnancy or while breastfeeding.
• Storage _ Keep tightly capped in a cool, dry place away from direct light to maintain pH stability and acid effectiveness.
