What is it?
Glycolic acid is an alpha hydroxy acid (AHA) derived from sugar cane that acts on the stratum corneum by reducing corneocyte cohesion. In MartiDerm formulas it is normally used together with other acids from the same family to improve its efficacy and tolerance.
What does it do for your skin?
Because of its small size, glycolic acid is the AHA that penetrates the deepest levels of the epidermis. It reduces the thickness of the stratum corneum and corneocyte cohesion.
It also steps up natural collagen synthesis, making the skin more supple and elastic. This action makes it useful in treating skin alterations where there are clumps of dead cells, such as in acne or photoaging.
