Function of Sodium Hyaluronate
Sodium hyaluronate is an inherent component in the human body. It is a glucuronic acid and has no species specificity. It is widely present in tissues such as placenta, amniotic fluid, lens, articular cartilage, and dermal layer of skin; it is found in organs It is distributed in the cytoplasm and intercellular substance, which lubricates and nourishes the cells and cell organs contained in it.

Sodium hyaluronate plays an important role in the field of cosmetics:
1. Improve drug efficacy: as a carrier for ophthalmic drugs, it increases the retention time of drugs on the surface of the eye by increasing the viscosity of eye drops, improves the bioavailability of the drugs, and reduces the irritation of the drugs to the eyes.
2. Wrinkle resistance: Small molecule hyaluronic acid can penetrate into the dermis layer, promote blood microcirculation, help the skin to absorb nutrients, and play the role of beauty and anti-wrinkle health care.
3. Moisturizing: Compared with other moisturizing agents, the relative humidity of the surrounding environment has little effect on its moisturizing properties.
4. Nutrition: Sodium hyaluronate is an inherent biological substance of the skin, and exogenous sodium hyaluronate is a supplement to the skin's endogenous sodium hyaluronate. Sodium hyaluronate of lower quality can penetrate into the epidermal layer of the skin, promote the supply of skin nutrients and excretion of wastes, thereby preventing skin aging and playing a beauty and nourishing role.
5. Repair skin and prevention of skin damage: Sodium hyaluronate can promote the regeneration of epidermal cells and the role of scavenging oxygen free radicals, which can promote the regeneration of skin at the injured site. It also has a certain preventive effect before use.
6. Thickening: Sodium hyaluronate has a high viscosity in aqueous solution, and its 1% aqueous solution is in the form of a gel, which can be used to thicken and stabilize cosmetics. |
