Sodium hyaluronate has moisturizing, nutritional, skin damage repair and prevention, lubricating and film-forming properties, thickening properties and anti-wrinkle properties on the skin. Sodium hyaluronate is the main component of connective tissues such as interstitial cells, vitreous body, and synovial fluid of the human body.
Sodium hyaluronate is usually used as a moisturizing effect in skincare products and has a certain role in locking moisture and moisturizing. Sodium hyaluronate is rich in moisturizing factors, which can improve the speed of skin metabolism during use so that the skin becomes more hydrated, and sodium hyaluronate can also increase skin elasticity, which can effectively prevent skin aging. Sodium hyaluronate has good transdermal absorption while moisturizing the skin, and can be better absorbed by the skin.
The moisturizing effect is the most important role of sodium hyaluronate in cosmetics. Compared with other moisturizing agents, the relative humidity of the surrounding environment has less influence on its moisturizing effect.
Sodium hyaluronate is a skin conditioning agent, an acidic mucopolysaccharide that naturally exists in the corneal epidermis and can absorb 1000 times its own weight of water, so as to retain skin moisture, prevent moisture loss through the epidermis, and prevent skin damage. It can improve the skin’s nutrition metabolism, make the skin soft and smooth, increase elasticity and prevent aging.
Sodium hyaluronate has a high viscosity in an aqueous solution, and its 1% aqueous solution is gel-like, and it can be added to cosmetics to thicken and stabilize. Sodium hyaluronate can promote the regeneration of injured skin by promoting the proliferation and differentiation of epidermal cells and scavenging free radicals, and also has a certain preventive effect.
