Who is it for: Suitable for any skin types from dry to normal. Oily skin or combination skin may want to target their dry or rough spots.


Why is it different: Our Hydroshield®Serum is based on years of medical research that identified a unique and proprietary technology that we named Hydroshield® Technology, that uses lipids that are virtually identical to the skin’s own lipids. As we age, skin lipids decline, leaving the skin dry and line prone. Our proprietary Hydroshield® Technology™ supplies a balance of skin identical lipids, ceramides and Essential Fatty Acids to help the skin lipid barrier to function at a much younger level. Once hydration and moisture is locked into the skin, the appearance of dry lines and wrinkles improve rapidly.
