What it is
Glycolic acid is the smallest AHA, derived from sugarcane. It exfoliates the surface of the skin, addressing dullness, uneven texture, and superficial pigmentation. In Korean formulas it is typically dosed mildly (low single digits %), often as part of layered toner or pad systems rather than high-concentration peels.
