Glycolic acid (or hydroxyacetic acid; chemical formula HOCH2CO2H) is a colorless, odorless and hygroscopic crystalline solid that is highly soluble in water. It is used in various skin-care products. Glycolic acid has antibacterial, antioxidant and humectant properties. Glycolic acid exfoliates the top layer of the skin, clearing acne and improving skin texture and tone. Glycolic acid is a type of alpha hydroxy acid (AHA), a group of natural acids derived primarily from fruits and milk. It is most commonly extracted from sugarcane. Chemically, it is the smallest molecule in the AHA family, which allows it to penetrate the skin deeply and work effectively. Originally derived from sugar cane, glycolic acid is one of the most commonly-used and effective alpha-hydroxy acids (AHA) in skincare. This powerful ingredient works by breaking down the bonds between dead skin cells to unclog the pores and gently purify the skin.
