Glycolic acid is an alpha hydroxy acid that is derived from sugar cane. It is one of the most popular anti-ageing active ingredients. Its small molecular structure – it has the smallest molecule of all alpha hydroxy acids – allows penetration into skin cells. Glycolic acid cleaves the bonds between keratinocytes on the horny layer and weakens the bonding properties of the lipids that retain the skin's dead cells, thus removing them. This results in the immediate and intense exfoliation of the horny layer, and simultaneous regeneration of cells. The systematic use of high concentrations of glycolic acid interacts with the fibroblast receptors, thus significantly stimulating the production of intercellular material (collagen, elastin, fibronectin, hyaluronic acid). The skin is therefore rejuvenated and regenerated. The 50% concentration in glycolic acid, in combination with the pH, result in targeted actions and indications.
