WHAT IS IT
Glycolic acid is a type of alpha-hydroxy acid, and is the smallest of the AHA group molecules. This means that glycolic acid penetrates the skin quite easily and is very effective.
Glycolic acid is an exfoliant, helping to shed dead skin cells to reveal the newer and brighter skin beneath. Glycolic acid is able to penetrate deeply and stimulate collagen production, so that skin feels firmer and the appearance of fine lines is reduced. Skin feels smoother and looks fresher, more radiant and evenly toned.
