Hyaluronic Acid, or HA, is a substance naturally produced by the body to lubricate joints, and support connective tissues and skin. At Jan Marini's high tech laboratories, we've created a patented and unique formulation containing three different molecular weights of HA combined with two supporting peptide technologies to help infuse skin and support the skin's own HA production. Whether you choose the Serum, Cream, Mask or Lip Complex, our HA technology provides instant hydration and barrier repair, while reducing trans-epidermal water loss.
