Improved potency

HA is the main component of connective tissues such as human intercellular stroma, eye vitreous body and joint synovial fluid. HA has the properties of retaining water, maintaining extracellular space, regulating osmotic pressure, lubricating and promoting cell repair in the body.As a carrier of ophthalmic drugs, it can prolong the retention time of drugs on the eye surface by increasing the viscosity of eye drops, improve the bioavailability of drugs and reduce the irritation of drugs to the eyes.

Adjuvant therapeutic effect: it can be injected directly into the joint cavity as a lubricant for the treatment of arthritis [1].Moisturizing sodium hyaluronate is one of the most important physiological functions in the skin tissue. Sufficient moisture makes the skin smooth and delicate.HA has the highest hygroscopic capacity at low relative humidity (33%) and the lowest at high relative humidity (75%), which is suitable for the skin's moisturizing needs for cosmetics in different seasons and different environmental humidity, without the feeling of greasy and clogging pores.

Wrinkle resistance

The level of skin moisture is closely related to the amount of hyaluronic acid in the skin, which decreases with age, weakening the skin's ability to hold water and causing wrinkles.Sodium hyaluronate aqueous solution has strong viscoelasticity and lubricity, applied on the skin surface, can form a layer of moisture permeable film, keep the skin moist and bright.Small molecules of hyaluronic acid can penetrate into the dermis, promote blood microcirculation, facilitate skin absorption of nutrients, and play a role in beauty and anti-wrinkle health care.

The film forming and lubricity Belongs to the polymers, lubrication are obvious when daub, feel is good, large molecules on the surface of the skin to form a layer of breathable film, make the skin smooth and moist, block the invasion of bacteria, dust etc, small molecule sodium hyaluronate can penetrate into dermis, has a slight expansion of the capillaries, increase blood circulation, improve intermediary metabolism, improve skin nutrition absorption,To achieve lubrication, full effect.

Sunscreen and skin damage repair effect on the skin surface can eliminate the active oxygen free radicals produced by ultraviolet radiation in the sun, protect the skin from ultraviolet damage, but also can promote the proliferation and differentiation of epidermal cells, promote the skin regeneration of the injured area.

Moisturizing effect

Experiments showed that compared with these moisturizers, sodium hyaluronate had the highest hygroscopic capacity at low relative humidity (33%) and the lowest at high relative humidity (75%).This kind of unique property, just adapt the skin to be in different season, below different environmental humidity, be like dry winter and moist summer, keep wet to cosmetic the requirement of action.The moisture of sodium hyaluronate is related to its quality, the higher the quality, the better the moisture performance.Sodium hyaluronate is rarely used alone as a moisturizer and is often used in conjunction with other moisturizers.

Nutritional role

Sodium hyaluronate is a biological substance inherent in the skin. Exogenous sodium hyaluronate is a supplement to the endogenous sodium hyaluronate in the skin.The hyaluronic acid sodium with lesser quality can infiltrate skin epidermis layer, the supply that promotes skin nutrition and waste excretion, prevent skin aging thereby, have hairdressing and raise yan effect.The maintenance of the skin is heavier than other make up, already became modern person hopes to raise yan consciousness.

Repair and Prevention

The skin gets the light burn that sunlight insolates place to cause or sunburn, if the skin becomes red, black, desquamate, basically is the role of ultraviolet ray in sunshine.Sodium hyaluronate can promote the regeneration of injured skin by promoting the proliferation and differentiation of epidermal cells and scavenging oxygen free radicals, and prior use also has a certain preventive effect.Its mechanism of action is different from the ultraviolet absorbent commonly used in sunscreen. Therefore, HA and ultraviolet absorbent are used together in sunscreen skin care products. It has a synergistic effect, which can reduce the penetration of ultraviolet rays and repair the skin damage caused by a small amount of ultraviolet rays at the same time, playing a double protective role.

The combination of sodium hyaluronate, EGF and heparin can accelerate the regeneration of epidermal cells and make skin tender, smooth and elastic.When the skin is mildly burned, a cosmetic with sodium hyaluronate on the surface can relieve the pain and speed up the healing of the skin at the injured area.

Lubrication and film formation

Sodium hyaluronate is a polymer with strong lubrication and film formation.Skin care products containing sodium hyaluronic acid when daub obvious lubrication, feel good.After coating on the skin, it can form a thin film on the skin surface, which can make the skin feel smooth and moist, and play a protective role on the skin.Contain hyaluronic acid sodium to protect hair product, can form a film on the hair surface, have moisturizing, lubricating, protect hair, eliminate static electricity and so on effect, make the hair easy to comb, elegant and natural.
