Details
Sodium hyaluronate is an inherent component in the human body. It is a kind of glucuronic acid and has no species specificity. It is widely present in placenta, amniotic fluid, lens, articular cartilage, skin dermis and other tissues; organs It is distributed in the cytoplasm and intercellular substance, and it lubricates and nourishes the cells and cell organs themselves.
At the same time, it provides a microenvironment for cell metabolism. It is a kind of human body's natural "hyaluronic acid" combined with other anti-wrinkle drugs that promote cell regeneration to make a gel, which is used by injection.
Moisturizing effect is the most important role of sodium hyaluronate in cosmetics. Compared with other moisturizers, the relative humidity of the surrounding environment has less influence on its moisturizing properties.
Other functions
HA is the main component of connective tissues such as human intercellular substance, vitreous body, joint synovial fluid, etc. It has the properties of retaining water in the body, maintaining extracellular space, regulating osmotic pressure, lubricating, and promoting cell repair. As a carrier of ophthalmic drugs, it increases the viscosity of the eye drops to extend the retention time of the drug on the ocular surface, improve the bioavailability of the drug, and reduce the irritation of the drug to the eyes.
The sodium hyaluronate aqueous solution has strong viscoelasticity and lubricity. When applied on the skin surface, it can form a moisturizing and breathable film to keep the skin moisturized and shiny. The small molecule hyaluronic acid can penetrate into the dermis to promote blood microcirculation, which is conducive to the absorption of nutrients by the skin, and plays the role of beauty and anti-wrinkle health care.
Film formation and lubricity belong to high molecular polymers. The lubricity is obvious when applied, and the hand feels good. The macromolecules form a breathable film on the skin surface to make the skin smooth and moist, blocking the invasion of foreign bacteria and dust, and the small molecules are transparent. Sodium can penetrate into the dermis, can slightly expand capillaries, increase blood circulation, improve intermediate metabolism, promote skin nutrient absorption, and achieve the effect of lubrication and fullness.
Sun protection and skin damage repairing effect on the skin surface can eliminate the active oxygen free radicals produced by ultraviolet rays in the sun, protect the skin from ultraviolet rays, and also promote the skin regeneration of the injured area by promoting the proliferation and differentiation of epidermal cells.
The combination of sodium hyaluronate, egf and heparin can accelerate the regeneration of epidermal cells, making the skin tender, smooth and elastic. When the skin suffers from mild burns and scalds, applying sodium hyaluronate-containing aqueous cosmetics on the surface can relieve pain and accelerate the healing of the injured area.
