Hyaluronan

Hyaluronic acid, also called hyaluronan, is an anionic, nonsulfated glycosamino-glycan distributed widely throughout connective, epithelial, and neural tissues. The total amount of hyalronan in the adult human body has been estimated to be 11–17 g.

Hyaluronan is a substance that is naturally present in the human body. The highest concentrations of it are found in fluids in the eyes and joints. Almost half of it is located in the collagen of skin. As a result of aging natural level of hyaluronic acid is depleted, that causes the skin to loose its suppleness and volume.

How does it work?

When it is applied to skin hyaluronic acid works as a cushion and lubricant. It helps to retain over a 1000 times its weight in water within the cells of skin that makes it an excellent moisturizer. No other biological substance can retain as much water as hyaluronic acid resulting in increased smoothness, softening and decreased wrinkles. Equally important is its ability to remove waste matter from cells including those where there is little blood circulation.
