Description: Glycolic acid is an alpha-hydroxy acid used mainly as an exfoliator on skincare. It gently lifts off dead skin cells and leaves the skin fresher and smoother. It stimulates the production of collagen, which in long-term use may help the skin to look firmer and younger. It also helps fade brown spots caused by sun damage. 

*Always use sunscreen after using glycolic acid and use products that show on label the percantage of acids and mode of use.
