Alpha Hydroxy Acid
AHA is a class of chemical compound, made up of natural ingredients. The most bioavailable form is that of Glycolic Acid which comes from sugars. AHAs with greater bioavailability appear to have deeper dermal effects, reaching beneath the top layer of skin where it nourishes and hydrates the living cells. When those cells become the outer layer, your skin already has a head start in nourishment and hydration.
