The science behind skin care: Moisturizers

Abstract

Moisturizers provide functional skin benefits, such as making the skin smooth and soft, increasing skin hydration, and improving skin optical characteristics; however, moisturizers also function as vehicles to deliver ingredients to the skin. These ingredients may be vitamins, botanical antioxidants, peptides, skin-lightening agents, botanical anti-inflammatories, or exfoliants. This discussion covers the science of moisturizers.
