Hyalgan

Hyaluronic Acid is natural polysaccharide (sugar). In bone disorders (osteoarthritis), it works by reducing friction in the joints and helps them work smoothly. Hyaluronic Acid also has an anti-aging effect. When injected into the skin (on the face most often), it works by hydrating the skin, enabling it to retain more water. This creates a filling/plumping effect and potentially fights wrinkles and other signs of aging. As an eye drop/cream/gel, it forms a thin, protective layer that helps to lock in moisture, preventing excessive evaporation of tears and maintaining a stable tear film.
