Sodium Hyaluronate is the sodium salt form of hyaluronic acid, a naturally occurring glycosaminoglycan found in human skin, connective tissues and synovial fluid. In topical skincare formulations, this ingredient is valued for its exceptional water-binding capacity (reported to hold up to approximately 1,000 times its weight in water) which enables profound hydration, improved skin plumping, diminished appearance of fine lines and enhanced barrier resilience.

Furthermore, because of its relatively low molecular weight variants and improved stability compared to hyaluronic acid, it permeates more deeply into epidermal layers, thereby supporting improved dermal hydration, fibroblast activity and skin-surface smoothness. In hair-care and scalp-care systems, Sodium Hyaluronate is increasingly utilised to maintain scalp hydration, reinforce moisture retention on the hair shaft and contribute to improved manageability of strands by promoting a hydrated environment that helps mitigate brittleness and frizz. By virtue of its humectant and film-forming behaviour, hair-care products incorporating Sodium Hyaluronate may deliver a more pliable texture, improved comb-through feel and enhanced scalp comfort — particularly in formulations for dry, chemically-treated or sensitivity-prone hair.
