As compared to exfoliants that rely on acids or granules, enzymatic exfoliants are exceedingly gentle and dissolve only dead skin cells without affecting the deeper layers of the skin.  This is a truly unique enzyme peel that is perfect for sensitive skin. It starts as a cool gel and morphs into an oil on the skin as the papaya enzymes activate, leaving skin perfectly smooth.  Dr. Sherber recommends this as a lip treatment to remove dry skin, since it's more targeted and effective than harsh sugar scrubs, and also recommends this to her laser patients post-treatment before they can return to glycolics and retinoids.
