hydroxy acids (AHAs) are acids that help with exfoliation of the skin. There are
many different types of AHAs but most commerical products contain either glycolic
acid or lactic acid.
At low concentrations (the levels usually used in acne treatment)
AHAs cause detachment of skin cells. In doing so, this helps to normalize the
way the skin is turning over, decreasing skin stickiness and helping to unplug

MD Forte, Glyone, and others.
