In human skin, hyaluronic acid has the ability to bind water in the tissue. However, as the amount of hyaluronic acid decrease with age, les water is bound, making the skin look older, less elastic and less resilient.
Hyaluronic acid has many functions, but primarily it holds water in the tissues by binding water molecules to cells and tissues.
This helps to provide the medium need for numerous body process and molecular transport. The large amount of fluid that is held by the polymers permits diffusion of solutes between capillaries and cells.
In the synovial cavity, the viscosity of the synovial fluid assists in lubrication of joints, which acts to dampen shock.
