Sodium Hyaluronate
What is Sodium Hyaluronate?
Sodium Hyaluronate is the sodium salt form of hyaluronic acid, a naturally occurring polysaccharide composed of repeating units of glucuronic acid and N-acetylglucosamine. Found abundantly in the skin's extracellular matrix, connective tissues, and synovial fluid, it plays a key role in maintaining tissue hydration and structure. In cosmetics, it appears in serums, moisturizers, creams, and masks within skincare formulations. As a humectant, it attracts and retains water molecules from the environment and deeper skin layers, supporting the skin's moisture barrier. Its smaller molecular size compared to hyaluronic acid allows better penetration into the upper skin layers, aiding in hydration delivery without altering the skin's natural pH.
