Product Description:

Hyaluronic acid (HA), also known as hyaluronan, is a naturally occurring, non-sulfated glycosaminoglycan (GAG) composed of repeating disaccharide units of D-glucuronic acid and N-acetyl-D-glucosamine linked by β-1,3 and β-1,4 glycosidic bonds. It is a high molecular weight biopolymer widely distributed in connective tissues, synovial fluid, and the vitreous humor of the eye. Its primary applications are in the pharmaceutical, biomedical, and cosmetic industries. In pharmaceuticals, it serves as a highly functional excipient, particularly in ophthalmic surgery (as a viscoelastic protector), in viscosupplementation for osteoarthritis, and in advanced drug delivery systems (e.g., for sustained release and targeted delivery) due to its excellent biocompatibility, biodegradability, and viscoelastic properties. It is also a key bioactive ingredient in dermal fillers and high-end skincare products for its profound moisturizing and skin-rejuvenating effects. As a critical biological macromolecule, hyaluronic acid is extensively used in life science research for studying cell signaling, motility, and proliferation, as it is a major component of the extracellular matrix and interacts with specific cell surface receptors like CD44.
