Being well known for its skin exfoliating functions, Alpha Hydroxy Acid often comes in the form of glycolic and lactic acids. By loosening the surface binds to promote cell turnover process and removing dead cells, they help reduce fine lines and wrinkles, even skin tones, and refine the skin texture. Lactic acid also acts as a skin moisturizer. Another role of AHAs is to adjust pH balance of the skin to ensure the skin is balanced and healthy.
