Glycolic acid is an alpha-hydroxy acid derived from sugar cane that exfoliates by loosening bonds between dead skin cells on the surface, promoting cell turnover and improving texture, tone, and fine lines. It is one of the smallest AHAs, allowing relatively deep penetration into the skin.
Salicylic acid is a lipid-soluble beta-hydroxy acid that exfoliates the skin surface and penetrates sebaceous pores to loosen and dissolve keratin and debris. It is widely used to treat acne, blackheads, and conditions involving thickened or scaly skin.
