Hyaluronic acid is a linear mucopolysaccharide that is widely found in the organelle of the living tissue. The role of sodium hyaluronate in the body includes: water retention, maintenance of extracellular space, regulating osmotic pressure, lubrication, and promote the important physiological function of cell repair. With the increase of age, the body synthesis of hyaluronic acid will gradually less than the speed of decomposition, hyaluronic acid content of the reduction, making the skin began to decline in water, the body's aging from the beginning. Topical hyaluronic acid only applied to the surface of the skin smear, play the role of lubrication and water retention, there are great limitations. And oral hyaluronic acid by digestion and absorption, increase the content of endogenous hyaluronic acid, the skin moist and glossy, flexible.

Hyaluronic acid in addition to the presence of the skin, also exists in the body of other tissues and organs, such as the joint cavity, blood vessels and heart. The reduction in hyaluronic acid in these tissues can lead to arthritis, atherosclerosis and brain atrophy. As in daily food hyaluronic acid is difficult to add, direct oral hyaluronic acid can guarantee a sufficient amount of active ingredients, supplement the daily loss of hyaluronic acid.
