ヒアルロン酸ナトリウム

Sodium hyaluronate, chemical system (C14H20NO11Na)n, is an inherent thing of the human body, is a glucuronic acid, no particular species, it is extensively current in placenta, amniotic fluid, lens, articular cartilage, pores and skin dermis and different tissues and organs. It is disbursed in the cytoplasm and interstitium, which lubricates and nourishes the cells contained in it and the cell organs themselves.

It additionally presents a microenvironment for cellphone metabolism. It is a gel made from a herbal "hyaluronic acid" in aggregate with different pills that promote phone regeneration and wrinkle reduction, and is administered via injection.

Moisturizing impact is the most necessary function of sodium hyaluronate in cosmetics, and in contrast with different moisturizers, the relative humidity of the surrounding surroundings has much less affect on its moisturizing property.

Enhance efficacy

HA is a primary issue of connective tissue such as human interstitium, vitreous physique of eye and synovial fluid of joint. It has the houses of maintaining water, keeping extracellular space, regulating osmotic pressure, lubricating and promotion phone restore in the body. As a provider of ophthalmic drugs, it prolongs the retention time of capsules on the eye floor through growing the viscosity of eye drops, improves the bioavailability of drugs, and reduces the infection of tablets on the eye.

Adjuvant therapy: It can be at once injected into the joint cavity as a lubricant for the cure of arthritis [1]. The moisturizing feature of sodium hyaluronate in pores and skin tissue is one of its most necessary physiological functions, and adequate moisture makes the pores and skin easy and delicate. HA has the very best hygroscopic ability beneath low relative humidity (33%) and the lowest hygroscopic capability underneath excessive relative humidity (75%), which is appropriate for the skin's moisturizing wishes for cosmetics in extraordinary seasons and special environmental humidity, and does no longer have the feeling of being fatty and blocking off pores.

Wrinkle resistance

The moisture degree of the pores and skin is carefully associated to the content material of hyaluronic acid. With the extend of age, the content material of hyaluronic acid in the pores and skin decreases, which weakens the water retention characteristic of the pores and skin and produces wrinkles. Sodium hyaluronate aqueous answer has sturdy viscoelasticity and lubricity. When utilized to the pores and skin surface, it can shape a moisturizing breathable movie to preserve the pores and skin moist and shiny. Small molecules of hyaluronic acid can penetrate into the dermis, promote blood microcirculation, is conducive to the absorption of vitamins in the skin, and play a fitness care position in splendor and anti-wrinkle.

Film formation and lubricity belong to excessive polymer, which has apparent lubrication and desirable hand sense when applied. Large molecules shape a breathable movie on the pores and skin surface, making the pores and skin easy and moist, blockading the invasion of overseas micro organism and dust. Small molecules of sodium hyaluronate can penetrate into the dermis, barely make bigger capillaries, expand blood circulation, enhance intermediate metabolism, and promote pores and skin nutrient absorption. Achieve lubrication, full effect.

Sunscreen and pores and skin injury restore characteristic on the pores and skin floor can cast off the reactive oxygen species generated by means of ultraviolet radiation in the sun, guard the pores and skin from ultraviolet damage, and additionally promote the regeneration of the pores and skin at the injured web page by means of promotion the proliferation and differentiation of epidermal cells.

Moisturizing effect

Experiments confirmed that in contrast with these humectants, sodium hyaluronate had the very best hygroscopic potential at low relative humidity (33%) and the lowest hygroscopic potential at excessive relative humidity (75%). This special nature is tailored to the pores and skin in distinctive seasons, one of a kind environmental humidity, such as dry iciness and moist summer, the moisturizing impact of cosmetics requirements. The moisture retention of sodium hyaluronate is associated to its quality, the greater the quality, the higher the moisture retention. Sodium hyaluronate is not often used as a humectant alone, and is regularly used in aggregate with different humectants.
