Hyaluronic acid is a kind of by DN - acetylglucosamine and D - glucuronic acid of the structure unit of macromolecular polysaccharide, a rigid cylindrical spiral on the space structure, produce strong hydrophilicity, and combined with the water molecules lock it in the double helix columnar structure, make the moisture not easily loss, so it is of special water effect, is currently the best moisturizing effect substance found in nature, known as the ideal Natural moisturizing factor, NMF). Can firmly lock 1000 times the weight of its own moisture and make the skin to maintain enough moisture and filling elasticity.

Human oral hyaluronic acid has the effect of beautifying the skin and delaying aging. The content of hyaluronic acid in the human body increases with age. Therefore, it is necessary to supplement exogenous hyaluronic acid after the age of 25. Generally, meat foods such as animal pigskin and cockscomb can provide part of hyaluronic acid, but the quantity Rarely, the human body can synthesize part of hyaluronic acid, but the mechanism is not clear. It is said that zinc can stimulate the synthesis of hyaluronic acid in the body. There is no data. Human oral hyaluronic acid can increase the precursor of hyaluronic acid synthesis in the body, and mice administration experiments have proved that oral hyaluronic acid can indeed increase the hyaluronic acid content in the body.
Physiological function:
The main physiological function of hyaluronic acid: It is the main component of the intercellular and extracellular matrix, maintaining the normal structure and function of cells.
1 Water retention
There are a large number of negatively charged carboxyl groups and polar groups on the surface of HA molecules, which are firmly locked after being combined with water molecules by hydrogen bonds.
2 Lubrication
HA is the main component of the synovial fluid in the joint cavity of the organism. Its good viscoelasticity and lubricity can reduce the pressure and wear of the joints when the body moves. Experiments show that HA and the peptide and glycopeptide complex in synovial fluid play a lubricating effect together.
3 Heal wounds
The proven wound healing effects of HA are as follows: (1) The clot composed of fibrin plays a structural function in the wound healing process; (2) Promotes the phagocytic activity of granulocytes and regulates inflammation; (3) Local degradation The low Mr HA can promote angiogenesis.
4 Various effects on cells
It is known that HA has the functions of protecting cells, affecting cell movement, proliferation and differentiation, and affecting the phagocytic function of cells.
