Hyaluronic acid (HA) or uronic acid is a linear macromolecular polysaccharide composed of disaccharide units (glucuronic acid -N- ethylthioglucosamine), which is a naturally occurring substance in tissues. Widely distributed in connective tissue, mucous tissue, eyeball lens and some bacteria in nature, it plays an important role in the dermis of human skin, and plays an important role in the overall maintenance of tissue structure and the transportation between cells.

Because of its nerve blocking effect, it is very commonly used in neurology, ophthalmology, plastic surgery and cosmetic surgery.
