Характеристики

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.

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.
