Acid hyaluronic(Hyaluronic acid, abbreviated as HA), also known as hyaluronic acid, is a high molecular weight polysaccharide composed of N-acetyl glucosamine and D-glucuronic acid disaccharide units. The molecular weight ranges from 1kDa to 3MDa. Commercially available hyaluronic acid is generally in the form of its sodium salt, called sodium hyaluronate. Huaxi Bio has been focusing on the research and production of sodium hyaluronate for more than 20 years, and can accurately control the molecular weight range of HA, providing sodium hyaluronate of various molecular weight ranges; at the same time, it can provide comprehensive technical support from product use to efficacy evaluation. Cosmetic-grade HA has the characteristics of high safety, high purity, and low impurities.
