D-glucuronic acid and n-acetyl-d-Glucosamine disaccharide unit composed of hyaluronic acid (Hyaluronan), also known as uronic acid, hyaluronic acid, basic structure of a disaccharide is composed of two units of d-glucuronic acid and n-acetyl-d-Glucosamine large consisting of polysaccharides. Different from other glycosaminoglycans, it does not contain sulfur.

Hyaluronic acid is an acid Mucopolysaccharide, 1934 United States Colombia Meyer, a Professor of ophthalmology at the University, first isolated from bovine vitreous substance. Hyaluronic acid for its unique molecular structure and physicochemical properties of displaying a variety of important physiological functions in the body, such as lubricating the joints, regulate the permeability of the vascular wall, regulate protein, electrolyte water diffusion and running to promote wound healing. Particularly important is, hyaluronic acid has a special water retention was found best moisturizing substance found in nature, is called ideal natural moisturizing factors (Natural moisturizing factor,NMF, for example: 2% pure hyaluronic acid solution to securely maintain a 98% water. Hyaluronic acid is a versatile matrix and hyaluronic acid (Restylane) HA is widely distributed in various parts of the human body. Skin also contains large amounts of hyaluronic acid. Human skin is mature and aging also changes with hyaluronic acid and metabolism, it can improve skin metabolism, making the skin soft, smooth, wrinkle, increases elasticity and prevent aging, while moisturizing and good transdermal absorption enhancers.
