Derived from sugar fermentation, lactic acid is an alpha hydroxy acid (AHA) that exfoliates the skin by dissolving the bonds that hold dead cells together. Lactic acid is considered to be a milder, more hydrating AHA. Eleven signal peptides (made up of amino acids, which form proteins in the skin) and safe, plant-derived growth factors help to boost the skins self-renewal, binding moisture to the skin and plumping, firming, and restoring bounce. A mix of quick-absorbing amino acids soothes, strengthens, and moisturizes the skin. Known for its hydration-boosting properties, this ingredient adds antioxidant benefits to the skin while helping defend against dehydration.
