Alpha hydroxy acids (AHAs) are substances of a natural origin that enable skin renewal in a soft, safe and effective way. The mixture of AHAs contains glycolic acid, lactic acid, malic acid, tartaric acid and citric acid.

They act by producing a gentle exfoliation (soft peeling) on the outer and damaged layers of the stratum corneum of the epidermis. Their effect is not keratolytic, that is, it is not based on the decomposition of the keratin of the corneocytes, but on a keratoplastic effect of cement dissolution that holds them together. As a result, the most external layers of the epidermis lose cohesion and detach easily. The result is a renewal of the surface of the skin manifested by a great improvement in general skin uniformity and the reduction of small wrinkles and furrows. The skin looks more even, silky and soft.

By causing a progressive elimination of clumps of dead skin surface cells, AHAs produce a more even tone. In addition, they enhance the rejuvenating action, encouraging the synthesis of mucopolysaccharides, collagen, elastin and reticulin, essential components of the dermis.
