Hyaluronic Acid (HA) is a mucopolysaccharide composed of repeat disaccharide units of N-acetylglucosamine and glucuronic acid. Natural high-viscosity mucopolysaccharide with alternating β1,3-glucuronidic and β1,4-glucosaminidic bonds. Principal glycosaminoglycan in connective tissue fluids. The molecular weight of Hyaluronic Acid, Sodium Salt, is in the range of 5.0 x 105 - 1.2 x 106, as calculated from its limiting viscosity. The commercial HA is commonly a sodium salt, called sodium hyaluronate. Appearance: White powder.

The principal component is the sodium salt of hyaluronic acid (0.2%). Hyaluronic acid is a biological polysaccharide (glycosaminoglycan) and is a major component of the extracellular matrix of connective tissues. HA is widely found in the extracellular matrix of animal tissues and vitreous humor. Its main biological role is water retention and lubrication.

Hyaluronic acid is a member of the family of molecules known as glycosaminoglycans. This family also includes chondroitin sulphate and some other large carbohydrate-containing molecules. The special structure characteristic of HA makes it has high moisturizing and water content reguating function and its solution has high viscoelasticity and lubricity. HA can penetrate into dermis layer, fully combine with water, promote skin blood microcirculation and nutrient absorption and maintain normal metabolism, and as a result it plays a role of wrinkle removing, look improving and health protecting.
