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