SkinMedica HA5 Rejuvenating Hydrator is the only product on the market that simultaneously delivers instant hydration and actively supports the skin's own ability to replenish its natural hyaluronic acid supply — addressing both the immediate and long-term drivers of dry, lined, and rough-textured skin. Powered by SkinMedica's exclusive VITISENSCE® Technology, it produces visible smoothing of fine lines and wrinkles immediately upon application and provides up to 8 hours of continuous hydration.Five forms of Hyaluronic Acid work at different molecular weights and skin depths simultaneously: Sodium Hyaluronate Crosspolymer provides long-lasting surface hydration through an extended-release mechanism. Hydrolyzed Hyaluronic Acid penetrates deeper into the epidermis to hydrate from within. Standard Sodium Hyaluronate provides immediate surface plumping. Hydrolyzed forms deliver HA fragments that diffuse into the skin layers. Together, the five-HA complex creates a hydration system that works from the surface to the deeper epidermis. VITISENSCE® Technology — combining Grape Flower Stem Cell Extract (antioxidant), a Peptide Complex for rejuvenation support, and Polysaccharides from French Polynesia — supports the skin's mechanisms for replenishing its own HA, ensuring long-term hydration improvement with consistent use.Fragrance-free, oil-free, non-comedogenic.
