Hyaluronic acid (HA), also known as hyaluronan, is an important disaccharide found in every tissue of the body, but in particular as an essential lubricant of healthy joints, skin and eyes. It is part of a group of macromolecules in the body labeled as glycosaminoglycans (GAGs), which are primarily in cell membranes and in the intercellular matrix of connective tissue. Along with water, HA’s unique property of high viscosity, and therefore low compressibility, provides vital shock absorption and lubrication properties.

Hyaluronic acid has been used as a bladder instillation for interstitial cystitis in Canada and Europe under the product name Cystistat. Pure HA, by Neocell, is extracted from hen's combs.
