Hyaluronic acid (HA for short), also known as Restylane, is a mucopolysaccharide composed of N-acetylglucosamine and D-glucuronic acid as disaccharide units. Its molecular weight ranges from 1kDa to 3MDa. Commercially available hyaluronic acid is generally in its sodium salt form and is known as sodium hyaluronate. Thereinto, the mean molecular weight of Low Molecular Weight Sodium Hyaluronate (HA-TLM 3-5S) is 30K～50K Da.With more than 20 years of dedicated research and production of sodium hyaluronate, Bloomage Biotech 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.
