    Hyaluronic acid (HA) is a large polysaccharide that is found naturally throughout the body and in high concentrations in the skin, the joint fluid, and the eye. It plays a role in many important bodily functions, including wound healing, joint lubrication and ovulation. As a supplement, it is most frequently used for joint health, to treat dry eyes, and in anti-aging products for the skin.
