HA is a natural intrinsic substance of the skin. Additional out-source HA may act as a supplement to the intrinsic HA of the skin. The low molecular weight HA can penetrate through the surface of the skin and accelerate the excretion of wastage and the supply of nutrition of the skin, so that it can prevent the skin from ageing. That means HA may function as a cosmetic substance as well as a nutrient.
