Sodium hyaluronate, whose chemical formula is (C14H20NO11Na)n, is an inherent component in human body. It is a glucuronic acid with no species specificity. It is widely found in tissues and organs such as placenta, amniotic fluid, lens, articular cartilage and dermis. It is distributed in the cytoplasm and interstitium, which lubricates and nourishes the cells and cellular organs themselves.
It also provides a microenvironment for cell metabolism. It is a gel made from a natural hyaluronic acid, which is used as an injection, along with other cell-boosting anti-wrinkle drugs.
Moisturizing effect is the most important effect of sodium hyaluronate in cosmetics. Compared with other moisturizing agents, the relative humidity of the surrounding environment has less influence on its moisturizing effect.
The traditional theory is that the formation of wrinkles is related to the breaking or loss of collagen elastic fibers. Modern medical research has found that another root cause of wrinkle formation is the change in the intercellular quality, that is, the reduction of the invisible component between cells "hyaluronic acid", while the cell scaffolding and elastic fibers are still present. Micro-plastic surgery is to replace the missing intangible interstitial components, and then change the metabolic environment of cells and water and ion balance, so as to increase the viscoelasticity of the skin, to achieve cosmetic effects. Sodium hyaluronate is the main component of articular synovial fluid and one of the components of cartilage matrix. It plays a lubricating role in joints and reduces the friction between tissues. Intraarticular injection can significantly improve the inflammatory response of synovial tissue, enhance the viscosity and lubrication function of articular fluid, protect articular cartilage, promote the healing and regeneration of articular cartilage, relieve pain, and increase the range of motion of joints. Intraarticular injection, 25mg once a week, once a week for 5 consecutive weeks, must be strictly aseptic.
