What is Hyaluronic acid ? Hyaluronic acid(HA) is a straight chain macromolecular mucopolysaccharide composed Of repeat disaccharide units of glucuronic acid and N-acetylglucosamine. It widely consists in the extracellular space of human and animal tissue, vitreum, umbilical cord, skin joints synovia and cockscomb, etc. The commercial HA is commonly a sodium salt, called sodium hyaluronate, habitually called hyaluronic acid. HA is a new biological at home and abroad. Its molecular weight is from several ten thousand to several million. It's aqueous solution has outstanding moisture keeping ability, high viscoelasticity and lubricity. It is widely used in cosmetics, pharmacy and health and beauty food. Applications: Biochemical drugs with high clinical value, which are widely used in all kinds of eye surgery, such as crystal implantation, corneal transplantation and glaucoma surgery, etc.Can also be used to treat arthritis and accelerate wound healing.Used in cosmetics, it can have unique skin protection effect, can keep skin moist and smooth, delicate, soft, elastic, has the anti-wrinkle, anti-wrinkle, beauty care and restore the skin physiology function. 1.

High safety Ecocert certification Non-animal origin bacterial fermentation A series of safety tests carried out by authorized testing organizations Ã? High purity Very low impurities (such as protein, nucleic acid and heavy metal) No pollution of other unknown impurities and pathogenic microorganism in production process assured by strict production management and advanced equipments Ã? Professional Service Customerized products All-around technical support for HA application in cosmetic 3. Functions of hyaluronic acid The molecular weight of Sodium Hyaluronate is 1 kDa~3,000kDa. Sodium Hyaluronate with different molecular weight has different function in cosmitics.
