Sodium hyaluronate, with the chemical formula (C14H20NO11Na)n, is an inherent component in the human body. It is a glucuronic acid and has no species specificity. It is widely found in the placenta, amniotic fluid, lens, articular cartilage, and skin The dermis and other tissues; in organs, it is distributed in the cytoplasm and intercellular substance, and it lubricates and nourishes the cells contained therein and the 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.
Improve efficacy
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.
Wrinkle resistance
The moisture level of the skin is closely related to the hyaluronic acid content. With age, the hyaluronic acid content in the skin decreases, which weakens the skin's water retention function and causes wrinkles. Sodium hyaluronate aqueous solution has strong viscoelasticity and lubricity. When applied to 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.
Moisturizing effect
Experiments show that compared with these humectants, sodium hyaluronate has the highest moisture absorption under low relative humidity (33%), and the lowest moisture absorption under high relative humidity (75%). This unique property is adapting to the skin's requirements for the moisturizing effect of cosmetics in different seasons and different environmental humidity, such as dry winter and humid summer. The moisturizing property of sodium hyaluronate is related to its quality. The higher the quality, the better the moisturizing property. Sodium hyaluronate is rarely used alone as a humectant, and is often used in conjunction with other humectants.
Nutrition
Sodium hyaluronate is a biological substance inherent in the skin, and exogenous sodium hyaluronate is a supplement to the skin's endogenous sodium hyaluronate. The low-quality sodium hyaluronate can penetrate into the skin epidermis to promote the supply of skin nutrition and the excretion of waste, thereby preventing skin aging and playing a role in beauty and beauty. Skin care is more important than other makeup, and it has become the modern people's awareness of beauty.
