The performance of hyalurinoic acid
Hyaluronic (Hyaluronic acid) a word comes from the Greek hyalos, mean glassy state or transparent, Hyaluronic acid was isolated from the eye tissues work completed in 1934, amiable in many other organizations also found evidence of Hyaluronic acid, for example, synovial fluid, cartilage, umbilical cord, etc., the article described the Hyaluronic acid is to have the same structure and physiological activity. Hyaluronic acid (HA) is a straight chain high molecular weight polypolysaccharide, a kind of mucopolysaccharide or glycosaminoglycan, which is an important component of the extracellular matrix dermal connective tissue. Adults have a total of 15 grams of HA, half of which is found in the skin.

At skin pH of 7, HA carboxyl groups are almost completely ionized, resulting in a polyanion structure that can give skin excellent water coordination properties. This structure is produced mainly by skin keratinocytes and fibroblasts, and it takes 2-4.5 days to completely renew, which is shorter than the renewal cycle of collagen.

Because HA plays a very important role in skin regulation, its synthesis and degradation must be rapid and well controlled by physiological mechanisms. In fact, HA not only has the effect of maintaining tissue and filling, it also carries moisture through the skin. Because HA has a special chemical structure, its ability to retain water is quite amazing, for example 1GHA can be used as a ligand for 6L of water. Furthermore, the hard sheath formed by HA on the fibrin can also provide proper lubrication. HA's ability to resist external compression and maintain dermal structure is due to its electrostatic interaction with collagen fibrous matrix proteins and other GAGs to form large "bottle-brush shaped aggregates". The structure way of the intercellular matrix not only stable collagen fiber orientation, but also prevent them because too close and form the original fiber connections between, and then develop into insoluble collagen, make the skin strong, the aging age will gradually increase with age.

Finally, HA is completely surrounded by a sphere of hydration that facilitates the cell matrix's transfer of ions, solutes, and metabolites, much like a body column. In addition, it affects cell migration, differentiation, growth and adhesion, angiogenesis and the control of immune responses.
