A double action gel exfoliator, 2% glycolic acid penetrates skin to exfoliate and loosen dead skin cells while sand derived silica beads gently sweep them away. Glycolic Acid Infused: Glycolic acid works by speeding up cell turnover and helps dissolve the bonds that hold skin cells together. This allows dead skin cells to slough off more rapidly than they would on their own. It also provides anti-aging benefits by stimulating your skin to create more collagen. This works to allow more evenly pigmented skin cells to generate and take their place helping combat mild hyperpigmentation, like age spots, melasma, and scars.
