Nu Skin Milk Lotion is powered by Hexapeptide-2, which protects skin from potential discoloration initiators, as well as a Hydrating Blend of squalene, glycerin, and other ingredients that help provide skin hydration and conditioning benefits.  One of its other most important ingredients is Broad Spectrum UVA and UVB sunscreen agents (SPF 15), which help absorb the high- energy rays that initiate skin-damaging free radical chain reactions. Because UV rays are one of the most common causes of skin discoloration, it is important to intercept them before they damage the skin and trigger the activation of discoloration.  For the full benefits of our Tri-Phasic Bright line, use this lotion with the Tri-Phasic Bright Cleanser, Toner, and Night Cream.
