COSRX AHA/BHA Clarifying Treatment Toner: The Daily Acid Toner That Started the Trend
Before K-beauty normalized acid toners globally, COSRX was already making this one. The AHA/BHA Clarifying Treatment Toner combines low-concentration glycolic, lactic, and salicylic acids in a gentle daily toner format. It's not a dramatic peel. It's a maintenance-dose daily exfoliating toner for users who want consistent cell turnover without the sting or recovery time of stronger peels.
For over a decade this has been one of COSRX's bestsellers, particularly among acne-prone users and those new to chemical exfoliants. At $24.61 for 150ml, it's in the budget tier of K-beauty acid toners, with performance that consistently punches above its price.
What It Does
Low-concentration glycolic and lactic acids (AHA) accelerate surface cell turnover. Salicylic acid (BHA) breaks up sebum plugs inside pores. White willow bark provides additional gentle exfoliation. Daily use clears congested pores, refines texture, and supports tone evenness. Not a brightening powerhouse; a steady-state exfoliating maintenance product.
Who It's For
- Acne-prone skin: BHA penetration helps ongoing pore clearing.
- Congested or clogged pores: Regular exfoliation prevents buildup.
- Acid beginners: Gentle enough for starter routines.
- Combination skin: Refines texture across uneven zones.
- Budget-conscious routines: Strong value per ml.

How to Use
After cleansing, apply with a cotton pad or palms to clean skin. Start 2 to 3 times per week; build to daily use if tolerated. Follow with serum and moisturizer. Always follow with SPF the next morning. 150ml lasts 2 to 4 months with regular use.
Do not use on broken skin or immediately after other acid treatments. Space from retinol on alternate nights.
FAQ
Can I use this daily?
Most users build to daily use over 2 to 4 weeks. Start 2 to 3 times weekly, increase if skin tolerates. For sensitive skin, 2 to 3 times weekly is the sustainable ceiling. Always monitor for over-exfoliation signs: tightness, redness, flaking.
COSRX vs Pixi Glow Tonic or The Ordinary?
Different strengths and formulations. Pixi Glow is stronger glycolic at 5%. The Ordinary offers various single-acid products. COSRX is the most gentle of the three and works well as a beginner or daily-maintenance option. For stronger results, upgrade to single-acid products.
Will it make me sun-sensitive?
Yes. All chemical exfoliants increase photosensitivity. SPF the next day is non-negotiable.
How long until I see results?
Smoother texture in 2 weeks. Visible pore refinement and tone evenness in 4 to 8 weeks. Long-term acne prevention over 8 to 12 weeks.
Can I use with vitamin C or retinol?
Space carefully. Vitamin C AM, acid toner PM. Retinol on alternate nights from acid toner. Stacking all three same-day risks barrier damage for most users.
