Key ingredients include: 15% Glycolic Acid, an alpha hydroxy acid (AHA) with a very small molecule that easily penetrates the skin. Its acidic pH accelerates exfoliation, while Bentonite a highly absorbent clay that is saturated in fat, enables it to remove toxins and impurities from the tissue. Salicylic Acid 2% causes a keratolytic action which reduces intercorneocyte cohesion and removes dry, dead skin cells. Paraben-free. Fragrance-free.
