NOW® Solutions Glutathione Skin Brightener™ is a combination of two clinically validated ingredients that nourish from within to give skin a healthy glow.* First, glutathione helps to maintain normal expression of skin pigments, which can result in a bright and even skin tone, and helps to maintain skin’s natural moisture content and elasticity.* This product also features Ceramosides®, a plant extract highly concentrated in phytoceramides, which has been shown to moisturize skin from within and to maintain youthful skin appearance.
