When treating acne, it is important to avoid irritation. This generously sized 16 oz. ultra-gentle liquid Cleanser is carefully designed with only the gentlest cleansing ingredients to be pH balanced so it doesn"t overdry or strip the skin. It also produces a thick lather which cleanses just the right amount and rinses clean. This Cleanser was developed specifically for use with The Regimen (acne.org/regimen) but can also be used as a stand-alone cleanser for all skin types.
