Cosrx AHA 7 Whitehead Power Liquid 100ml

Cosrx AHA 7 Whitehead Power Liquid is a chemical exfoliant with 7% glycolic acid in an apple fruit water base that gently dissolves the bonds between dead skin cells to reveal smoother, brighter, more even-toned skin. AHA (alpha hydroxy acid) works on the skin surface to target whiteheads, rough texture, dullness, and uneven pigmentation.

Niacinamide (vitamin B3) provides additional brightening and pore-refining benefits. Panthenol strengthens the barrier. Sodium hyaluronate maintains hydration. The minimal, clean formula contains just 10 effective ingredients — no unnecessary fillers. An apple fruit water base delivers natural AHAs and antioxidants.

Pro tip: This is the AHA counterpart to the BHA Blackhead Power Liquid — use the AHA for surface concerns (whiteheads, dullness, texture) and the BHA for deeper pore concerns (blackheads, sebum). You can alternate between them on different nights. Start with 2-3 times per week and build up to nightly use as your skin tolerates it. Don't use on the same night as other strong actives (retinol, vitamin C) when first introducing. Sunscreen is absolutely essential when using AHA — glycolic acid makes your skin photosensitive.
