You may have first become acquainted with lactic acid in gym class. The same lactic acid that builds up in your muscles during a workout is the same lactic acid that is modeled in professional laboratories and blended into skin care products. That's because lactic acid is one of several highly effective alpha hydroxy acids revered for its ability to gently exfoliate the skin and enhance its overall appearance. It improves skin's texture by sloughing off dead surface cells and promoting collagen growth, reducing wrinkles and fine lines, evening skin tone and even calming inflammation. Lactic acid also delivers deep hydration, making it an ideal ingredient for facial moisturizers.
