Hyaluronic acid is an acidic mucopolysaccharide, which was first isolated from bovine vitreous in 1934 by Meyer, Professor of Ophthalmology at Columbia University. With its unique molecular structure and physicochemical properties, hyaluronic acid shows a variety of important physiological functions in the body, such as lubricating joints, regulating the permeability of blood vessel wall, regulating the diffusion and operation of protein, water and electrolyte, promoting wound healing and so on.
Main purpose
