Exfoliating Enzyme Cleanser

This enzyme cleanser exfoliates gently yet effectively to leave skin smoother, radiant and more even. The formula transforms from a fine powder into a rich lather upon contact with water and is powered by Papain Enzymes, Shikimic Acid and our signature NAC Y²™ complex to sweep away dead skin cells and unclog pores.
