Function
Hyaluronic Acid has outstanding moisture keeping ability, thus called Natural Moisturing Factor in the world.
Hyaluronic Acid is a common ingredient in skin-care products, which can be used as a very effective topical humectant, which can
be used for facial wrinkles, reduction of folds and wrinkles, and removal of scars.
Application
Hyaluronic Acid could be used in eye surgery, such as corneal transplantation, cataract surgery, glaucoma surgery, and surgery to
repair retinal detachment.
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
