Sodium Acetylhyaluronate
What is Sodium Acetylhyaluronate?
Sodium Acetylhyaluronate is the sodium salt of acetylated hyaluronic acid, a glycosaminoglycan naturally present in human skin and connective tissues. Produced through biotechnological processes, acetylation modifies the molecule for improved stability and solubility in cosmetic formulations. This derivative features a smaller hydrodynamic size than standard hyaluronic acid, enabling better penetration into upper skin layers. Primarily used as a humectant and skin conditioning agent in serums, creams, essences, and masks. It functions by binding water molecules from the surroundings and dermis, promoting moisture retention and supporting the skin's hydrolipidic film without adding oiliness. Its enhanced bioavailability makes it suitable for daily hydration-focused products.
