20% Glycolic Acid

Glycolic acid will improve the structural integrity of the skin far into the dermis. This strength is very beneficial for young, acne-prone teens and sensitive impure skins. Of all the alpha hydroxy acids, glycolic acid is the most potent in its capabilities for both rapid penetration and desquamation (exfoliation). The molecular structure of glycolic acid is much smaller than other AHAs, which increases its ability to be absorbed.
