Where to buy Hyaluronic acid with low price and high quality. We are your best choice, all informations about Hyaluronic acid are available.
Product Name: Hyaluronic acid
Hyaluronic acid source: Hyaluronic acid is a polymer of disaccharides, which are composed of D-glucuronic acid and D-N-acetylglucosamine, linked via alternating beta-1,4 and beta1,3 glycosidic bonds. Sodium hyaluronate is the sodium salt of Hyaluronic acid, commercial Hyaluronic acid is commonlyits sodium salt form, and usually it's still called as Hyaluronic acid (HA).
Hyaluronic acid introduction: Hyaluronic acid to give you better hydration, stability & lubrication.It is made by enzymatically cleaving high-molecular weight Hyaluronic acid into small fragments. Molecular weight <50kDa. Smaller molecules enhance skin penetration.Due to the much smaller molecular size of the molecule compared to regular Hyaluronic acid, the penetration is 50% better.
