COSRX AHA 7 Whitehead Power Liquid 100ml

Glycolic Acid dissolves the bonds between dead cells for faster turnover and brighter surface texture. This focused formula puts all its power behind one proven active for maximum impact.

This liquid is built around 7 percent glycolic acid, which makes it more treatment focused than a daily toner but still usable as part of a steady refining routine. Glycolic acid is one of the best-known AHAs for helping loosen the bonds between dead skin cells on the surface, which is why it is so useful for whiteheads, roughness, and dullness. When surface buildup is reduced, skin tends to reflect light more evenly and feel smoother to the touch. Apple water complements that exfoliating action by adding a skin-friendly base that helps the formula feel less flat or harsh than a simple acid solution. Because whitehead-prone skin can also become dehydrated, it is important that exfoliation does not completely strip the surface. That is why this kind of liquid works best when followed by hydrating products that support recovery and moisture retention. The science story is therefore targeted resurfacing: clear buildup, refine the surface, and support a visibly cleaner, brighter-looking complexion over time.
