Hyaluronic acid

hyaluronic acid

Hyaluronic acid — A glycosaminoglycan component, Hyaluronic Acid (HA) is a naturally occurring substance (in the dermis) and is found throughout the body. It plays an important role in tissue hydration, lubrication, cellular function, and the distribution of nutrients. Its water-absorption abilities and large molecular structure allow the epidermis to achieve greater suppleness, proper plasticity, and turgor.   When applied to the skin, HA forms a viscoelastic film in a manner similar to the way it holds water in the intercellular matrix of dermal connective tissues. This performance and behavior suggests that HA makes an ideal moisturizer base, allowing for the...

Glycosaminoglycans hyaluronic acid

Glycosaminoglycans — polysaccharides that are major components of the extra cellular matrix (ECM) and connective tissues. They are used in cosmetics for their ability to increase hydration, elasticity and pliability of the skin. Glycosaminoglycans are credited with film-forming, moisturizing, and firming properties. They reportedly leave the skin smooth, velvety soft 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. Glycosaminoglycans are derived from cartilaginous...
