Smooth, hydrated skin depends on Hyaluronic Acid (HA), a natural "water-loving" molecule found in the skin. HA holds in moisture, keeping skin healthy, resilliant and supple. HA also goes beyond hydration to improve epidermal health. HA5 is the first rejuvenating hydrator that supports overall epidermal health. Unlike other topical HA serums that only temporarily hydrate the surface, HA5 is powered by Vitisensce technology- a proprietary formulation that harnesses potent antioxidants found in Vitis flower stem cells and algae extracts to support the skins ability to replenish its own hyaluronic acid for overall epidermal health.
