Hyaluronic acid acts on the skin surface. Macromolecular hyaluronic acid can form a breathable film on the skin surface, while small molecular hyaluronic acid can penetrate into the dermis, which has the functions of slightly dilating capillaries, increasing blood circulation, improving intermediate metabolism and promoting skin nutrient absorption. It has strong anti-wrinkle function, can increase skin elasticity and delay skin aging. Hyaluronic acid can also promote the proliferation and differentiation of epidermal cells, scavenge oxygen free radicals, and prevent and repair skin damage. The aqueous solution of hyaluronic acid has high viscosity, which can make the water phase change thick. The paste emulsified by oil phase is uniform and fine, and the emulsion is stable. Hyaluronic acid is the best natural moisturizing ingredient in high-grade cosmetics. It has good compatibility and can be added to almost any beauty cosmetics. Widely used in face cream, lotion, lotion, essence, facial cleanser, shower gel, shampoo, mousse, lipstick and other cosmetics. Generally, the addition amount is 0.05%-0.5%.
