Uses

glycosaminoglycans is a group of chemically related polysaccharides that are major components of the extra cellular matrix (eCM) and of connective tissues. They are used in cosmetics for their ability to increase hydration and the elasticity and pliability of the skin. glycosaminoglycans are credited with film-forming, moisturizing, and firming properties. They reportedly leave the skin smooth and with a pleasant, velvety softness and evenness, and minimize wrinkle appearance. They are easily accepted by the skin because of their high charge and affinity. This group of complex materials, formerly identified as mucopolysaccharides, includes such individual components as hyaluronic acid, chondroitin, chondroitin sulfate, chondroitin 6-sulfate, dermatan sulfate, heparin, and heparin sulfate. As proteoglycans, glycosaminoglycans are derived from cartilaginous fish. They can also be derived from various animal proteins as well as synthetically prepared.
