by COSRX
Updated August 25, 2026
7% glycolic acid exfoliant clears whiteheads and smooths skin texture; irritating for sensitive users.
What the community says
This 7% glycolic acid liquid targets developing whiteheads and rough texture, favored for quick results on breakouts. Best for oily, acne-prone skin that tolerates acids well. Overuse risks barrier damage and stinging, especially for sensitive or eczema-prone skin.
