HA is a natural biotic component widely presents in skin and other tissues. It has outstanding moisturizing effect, thus called Natural Molsturlzing Factor (NMF) in the world. HA is the best component used in cosmetics for moisturizing from the nature.
We could produce HA from 5,000~ 3 million Molecular Weight. When it is applied to skin, macromolecular HA can form a thin layer permeable to air, keeping the skin smooth and moist and further protecting it from bacteria, dust and ultraviolet rays, while micro molecular HA can penetrate 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 emulsification.
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

Suggeston for application
Sodium hyaluronate has a wide range of molecular weight, from
thousanda to millions of Daltons. The use effect of Solution
hyaluronate varies with its different molecular weight. For
cosmetic purpose, the molecular weight is usually not more than 1.5
million Daltons.
1.For facial cleanser and liquid agent (such as skin toner and
tender lotion):HA with a molecular weight of about 0.8 million
Daltons is recommended.
2.For cream, gel, skin emulsion and skin milk, HA with a molecular
weight of 1~1.3 million Daltons is recommended.
3.For eye care products like eye cream, HA with a molecular weight
of 1.3~1.5 million Daltons is recommended.
4. For efficacy-specific products like sun cream, additional
dosage(>0.1%) is recommended so as to fully exert the sustained
release function of Sodium hyaluronate, improve its efficacy and
extend its shelf life.
