 in the world. HA is the best component used in cosmetics for moisturizing from the nature.

dust and ultraviolet rays, while micromolecular HA can penetrat into corium, enlarging blood capillaries slightly, promoting blood circulation, improving intermediary
metabolism and nourishment-absorbing ability of skin, thus eliminating wrinkles, increasing skin's elasticity and delaying its aging. In addition, HA can further
hyperplasia of epidermic cell, clean oxygen-derived free radicals, prevent and rehabilitate skin injuries. Its aqueous solution has very high viscosity which can
make water become thicker. Cream made by emulsifying HA with oil is fine and even, homogeneous with stable emulsifiction.
◆HA is the best natural moisturizing component used in high-end cosmetics. Thanks to it’s good compatibility, HA can be added to almost any beauty cosmetics,
such as cream, lotion, astringent, essence, facial cleanser, shower gel, shampoo, hair conditioner, mousse and lip stick. In most cases, the dosage is around 0.05%-0.5%.
