Hyaluronic Acid

Hyaluronic Acid is a straight-chain macromolecular mucopolysaccharide composed of repeating disaccharide units of glucuronic acid and N-acetylglucosamine, known for its good skin moisturizing effect. Its molecular weight ranges from tens of thousands to millions. Its aqueous solution has excellent moisturizing properties, high viscoelasticity and lubricity. Hyaluronic acid exists in food, cosmetic and pharmaceutical grades, and pure hyaluronic acid is widely used in cosmetic, health and beauty foods. Molecular weight is 3K-2,000K Dalton, easily soluble in water.Hyaluronic acid can be formed a breathable film on the surface of the skin layer, which keeps skin smooth and moisturizing, and blocking external bacteria, dust, and UV intrusion and protects the skin from infringement. small molecular hyaluronic acid can infiltrate into the dermis, with the function of increasing blood circulation, improving intermediary metabolism, and promoting the absorption of nutrients, eliminating wrinkles, increasing skin elasticity, and slowing down skin aging. Hyaluronic acid also can promote epidermal proliferation and differentiation of cells to remove oxygen-free radicals to prevent and repair skin damage.
