The goal of effective cleansing is to loosen and remove dirt, germs, excess oils, dead cells, cosmetics and medication residues without irritating the skin or drawing away needed moisture. CeraVe Hydrating Cleanser gently cleanses the skin while helping to maintain the right moisture balance. It is proven to prevent moisture from escaping (evaporating) from the skin's surface. Its fragrance-free, moisturizing formulation is non-irritating and noncomedogenic (does not cause pimples or acne by clogging the pores).
