Lactic Acid is a gentle rapid exfoliator that is unlikely to cause visible peeling for most. If you are new to chemical peeling, this is the peel to try. If you have sensitive skin, lactic acid should work well for you. If you've hit a plateau with other acid treatments, this is a great alternative. Benefits: Loosens and removes the surface debris on the skin. Softens comedomes. Deep cleans pores. Softens fine lines. Great for mature skin for a plump, firm appearance. This particular formulation contains licorice extract, an extremely effective botanical skin-lightening additive. Is a non-irritating acid treatment and great for sensitive skin. No "down time", no noticeable flaking of the skin, just a sloughing-off of the dried, glued together sebum and surface skin debris.
