Think of this as a reset button for congested, dull, or uneven skin — in toner form. The COSRX AHA/BHA Clarifying Treatment Toner combines two types of chemical exfoliants in a gentle, daily-use formula that clears away dead skin cells, unclogs pores, and gradually reveals a smoother, more even complexion.

Here's the science made simple: AHA (glycolic acid) works on the skin's surface, dissolving the glue that holds dead skin cells together so fresher skin can show through. BHA (betaine salicylate) goes deeper, penetrating into pores to clear out excess oil and congestion — the stuff that causes blackheads and bumps. Together they cover both surface texture and pore clarity in one step.

What makes this formula special is how gentle it is. The AHA and BHA concentrations are deliberately low (0.1% each), making it one of the most beginner-friendly chemical exfoliants available. The formula also contains Willow Bark Water and Apple Fruit Water as natural exfoliant boosters, plus Panthenol to soothe and hydrate as the acids work. It comes in a spray bottle — mist onto a cotton pad and swipe, no rinsing required.

Sul Skin note: A brilliant entry point for anyone new to chemical exfoliation — effective but genuinely gentle enough for everyday use.
