COSRX AHA/BHA Clarifying Treatment TonerGlycolic Acid (AHA) + Betaine Salicylate (BHA). Willow Bark Water + Apple Fruit Water. Allantoin + Panthenol. 150ml.
Curious about chemical exfoliation but put off by the idea of separate acid products, complicated routines, or the risk of overdoing it — when all you actually want is clearer, smoother skin without the faff?
The UK skincare market has made acid exfoliation feel more complicated than it needs to be. Two separate products for AHA and BHA. Strict alternation schedules. Percentage anxiety. The reality for most people, especially those new to acids, or with skin that doesn't tolerate higher concentrations, is that a single gentle daily toner delivering both AHA and BHA at approachable levels is more effective than an inconsistent rotation of two stronger products. Less overthinking. More consistent results.
This is that toner, and at 150ml, it's built for daily use.
The One Toner That Does Both. Gently. Every Day.
Formulated with Glycolic Acid (AHA) and Betaine Salicylate (BHA) in a single lightweight formula, built on a base of Willow Bark Water and Apple Fruit Water, and balanced with Allantoin and Panthenol for soothing comfort, the COSRX AHA/BHA Clarifying Treatment Toner delivers the surface-smoothing power of AHA and the pore-clearing power of BHA in one effortless daily step. Gentle enough for sensitive skin, effective enough to produce genuine results, it is the ideal introduction to chemical exfoliation and the most consistent way to maintain clear, smooth, and radiant skin once established.
How To Use
How To Use:
Step 1 — Cleanse First
Apply to clean skin after your regular cleanser. Remove all makeup, SPF, and cleanser residue before application.
Step 2 — Spray onto a Cotton Pad
Spray an appropriate amount of toner directly onto a cotton pad — enough to dampen the pad without excess dripping.
Step 3 — Wipe Gently Across the Face
Using gentle, even strokes, wipe the cotton pad across the face — avoiding the immediate eye area and lip line. The wiping motion physically removes surface debris while the acids begin their exfoliating work.
Step 4 — Allow to Absorb Fully
Allow the toner to absorb fully before applying the next step of your routine — approximately 1 minute.
Step 5 — Continue Your Routine
Follow with essence, serum, and moisturiser as normal. The clarified skin surface after acid toner application improves the absorption of all subsequent products.
Step 6 — Apply SPF if Using in the Morning
If using as part of a morning routine, always finish with SPF 30 or greater. Acid exfoliation increases photosensitivity — sun protection is non-negotiable, and particularly important in the UK during summer months when UV levels are higher than commonly assumed.
PRO TIP: This toner is the ideal daily foundation for an acid routine on Skinza. Once skin has fully adjusted to daily use (typically 4–6 weeks), those wanting to step up their exfoliation can add the COSRX BHA Blackhead Power Liquid 2–3 evenings per week for targeted deeper pore-clearing, while maintaining this toner as the daily gentle exfoliation base — a combination that delivers comprehensive results across all skin concerns without over-exfoliating.
Recommended Use: Daily — AM or PM after cleansing. Suitable for beginners and sensitive skin. Always use SPF in the morning.
Avoid using with other acids (AHAs / BHAs / Retinols & Vitamin C) * Avoid when pregnant or breast feeding!
