Hyaluronic acid, also known as HA, is a polymeric mucopolysaccharide repeatedly linked by n-acetylglucosamine and D-glucuronic acid disaccharide units, with molecular weight ranging from 1kDa to 3MDa. Our company sells hyaluronic acid in its sodium salt form, called sodium hyaluronate, which can accurately control the molecular weight range of HA and provide sodium hyaluronate in various molecular weight segments. At the same time, it can provide a full range of technical support from product use to efficacy evaluation. Cosmetic grade HA has the characteristics of high safety, high purity and low impurity.
