Hyaluronic Acid can also be used to treat osteoarthritis of the knee. They are administered as a course of injections into the knee joint, which are believed to supplement the viscosity of the joint fluid, thereby lubricating the joint, cushioning the joint, and producing an analgesic effect.
Hyaluronic Acid has also been used in the synthesis of biological scaffolds for woundhealing applications. These scaffolds typically have proteins such as fibronectin attached to the Hyaluronic Acid to facilitate cell migration into the wound.
Hyaluronic Acid is also used in antiadhesive products, which are widely used in pelvic and abdominal surgery to prevent postoperative adhesions.

1.Hyaluronic acid is a substance that is naturally present in the human body. It is found in the highest concentrations in fluids in the eyes and joints.
2.The hyaluronic acid that is used as medicine is extracted from rooster combs or made by bacteria in the laboratory.
3.Hyaluronic acid is also used as a lip filler in plastic surgery.It is also using to prevent the effects of aging.
4.Hyaluronic Acid (HA, Hyaluronic, Cyclic Acid) is a critical component of the skin that helps to retain moisture, keeping the skin firm, and preventing wrinkles by adding volume to the skin.
The role of hyaluronic acid on the skin surface, molecules of hyaluronic acid can be formed on the surface of the skin layer of breathable film, the skin smooth and moist, and blocking external bacteria, dust, uv intrusion, protect the skin from infringement; small molecule transparent acid could infiltrate into the dermis, with a slight expansion of capillaries to increase blood circulation, improve intermediary metabolism, and promote the role of the skin to absorb nutrients, eliminate wrinkles with strong features, increase skin elasticity, slow down skin aging. hyaluronic acid can promote epidermal proliferation and differentiation of cells to remove oxygen free radicals, can prevent and repair skin damage. Hyaluronic acid aqueous solution of high viscosity, will enable the water phase thickening; emulsified with the oil phase even after the fine paste, the role of a stable emulsion, to prevent cells produce a number of enzymes to reduce the formation of free radicals in the prevention of free radical damage to cell structure, resulting in lipid peroxidation and aging, such as the body has an important role.
