Description
Sodium Hyaluronate is one of the components of human skin, which can prevent skin aging, improve skin touch and appearance. Some low molecular weight Sodium Hyaluronate can also penetrate into the dermis of skin, improve and regulate the metabolism of skin, make skin moist, smooth, delicate, tender and elastic, so as to play the role of wrinkle prevention, beauty and health care, and protect skin from aging. At the same time, it is a good penetration enhancer.Therefore, cosmetics containing Sodium Hyaluronate are also called "bionic cosmetics"; with the increase of age, the decrease of Sodium Hyaluronate in the body, oral health care products containing Sodium Hyaluronate can supplement the Sodium Hyaluronate in the body, which has the effect of improving the skin.It has been widely used in Japan, the United States and other countries.It has the following functions:
 
1, Moisturizing effect
Moisturizing effect is the most important role of Sodium Hyaluronate in cosmetics.Compared with other humectants, the relative humidity of the surrounding environment has little effect on its moisture retention.The moisturizers commonly used in cosmetics include glycerin, propylene glycol, sorbitol, polyethylene glycol, sodium lactate, sodium pyrrolidone hydroxy acid, etc.Experiments show that although the humectants such as glycerin, propylene glycol, sorbitol and polyethylene glycol will absorb water from the air under high humidity, they will absorb water from the inner layer of the skin rather than from the air under low humidity (especially in dry and cold weather).This will dry the skin.Sodium lactate, sodium pyrrolidone hydroxy acid and other humectants have been used in cosmetics, but their mechanism of action is far from fully understood because they are the components of cuticle and have the ability to combine with water.If only from their combination with hydrodynamics, as a moisturizer is not the ideal material.The moisture absorption of Sodium Hyaluronate is the highest at low relative humidity (33%), and the lowest at high relative humidity (75%).It has the function of automatically adjusting the best water retention according to the change of environmental humidity, so as to keep the moisture content of cuticle in the best physiological state.
 
2, Nutrition
Sodium Hyaluronate is an intrinsic physiological substance of skin, and exogenous Sodium Hyaluronate is a beneficial supplement to endogenous Sodium Hyaluronate of skin.Sodium Hyaluronate with low molecular weight can penetrate into the skin epidermis, promote the supply of skin nutrition and excretion of waste, so as to prevent skin aging and play the role of beauty and nutrition.Oral health food containing Sodium Hyaluronate plays the role of beauty and health care. At present, Sodium Hyaluronate is widely used in beauty health food in the United States, Japan and other developed countries.
 
3, Thickening
Sodium Hyaluronate has high viscosity in aqueous solution, and 1% of its aqueous solution is gelatinous. It can play a role of thickening and stabilization in cosmetics.
 
4, lubricity and film formation
Sodium Hyaluronate is a kind of polymer, which has a strong sense of lubrication and film-forming.When the skin care products containing Sodium Hyaluronate are applied, they have a clear sense of lubrication and good hand feel. After being applied to the skin, a film can be formed on the skin surface, which can make the skin have a good sense of smoothness and moisture, and play a protective role on the skin.The hair conditioner containing Sodium Hyaluronate can form a film on the hair surface, which can moisturize, lubricate and protect the hair, eliminate static electricity, and make the hair easy to comb and float naturally.
 
5, the repair and prevention of skin injury
Skin burns or sunburn caused by sun exposure, such as skin reddening, blackening, peeling, etc., mainly due to the role of ultraviolet rays in the sun.Sodium Hyaluronate can promote the regeneration of injured skin by promoting the proliferation and differentiation of epidermal cells and scavenging oxygen free radicals.Prior use has a good preventive effect. Therefore, Sodium Hyaluronate and ultraviolet absorbent are used together in sunscreen skin care products, which can not only reduce the penetration of ultraviolet rays, but also repair the skin damage caused by ultraviolet rays and play a dual protective role.
 
6, synergistic effect of Sodium Hyaluronate on sunscreen and post sun repair products
Sodium Hyaluronate has the function of eliminating free radicals. In the epidermis, it can remove the active oxygen radicals produced by ultraviolet irradiation in the sun, and protect the skin from its harm. It is called an efficient free radical scavenger.Oxygen free radicals can cause lipid peroxidation to destroy cell membrane, which is related to skin pigmentation.Sodium Hyaluronate reacts with oxygen free radicals, which are eliminated and degraded.Therefore, Sodium Hyaluronate has sunscreen effect.
 
Synergy - Total sunscreen is the latest market for sunscreen development.According to the concept of light cell immune protection, it is necessary to add natural cell protection compound in cosmetics for daily use, which is more important to protect skin immune ability than traditional sunscreen products.That is to say, we should not only consider the acute damage of ultraviolet rays, such as erythema and sunburn, but also consider the adverse reactions caused by chronic long-term exposure to ultraviolet rays, such as free radical formation, DNA damage, abnormal cross-linking of collagen, degradation of connective tissue, skin aging and skin cancer.Sodium Hyaluronate can promote the regeneration of the injured skin by promoting the proliferation and differentiation of epidermal cells and eliminating oxygen free radicals, which can be prevented by prior use.Sodium Hyaluronate in the epidermis can eliminate the active oxygen radicals produced by ultraviolet irradiation in the sun, and protect the skin from its harm.Sodium Hyaluronate has the function of sunscreen and its mechanism is different from that of ultraviolet absorbers. It has a synergistic effect when used in combination with ultraviolet absorbers in sunscreen skin care products. It can reduce the penetration of ultraviolet rays and repair the skin damage caused by the penetration of ultraviolet rays at the same time, playing a dual role in protection.
 
7, The synergistic effect of Sodium Hyaluronate in whitening and freckle removing products
Sodium Hyaluronate is used on the skin surface. The macromolecule part can quickly form a layer of permeable hydrated viscoelastic membrane on the skin, which can not only block the invasion of foreign bacteria and dust, but also keep the skin smooth.The low molecular part penetrates into the skin, slightly dilates the capillaries, increases the blood circulation, improves the intermediate metabolism, promotes the skin nutrition absorption, and plays its role in the epidermis.It has strong anti wrinkle function, increases skin elasticity and delays skin agingThe large ion function of Sodium Hyaluronate can regulate the flow and change of positive ions on the cell membrane surface and around the cell, change the diffusion rate of substances in the skin, and participate in the transport of water and electrolyte.Maintain the normal permeability of the arterial wall, improve the capillary blood circulation after degradation, improve the capillary blood circulation, keep the skin healthy and ruddy, and improve the adaptability of the skin to the changes of the external environment.
 
Whitening and freckle removing skin care products are no longer simply to inhibit melanin production or prevent sunburn, but to fight against aging and promote skin metabolism.Stimulate the regeneration of skin cells.Enhance skin immune function.Combined with the purpose of skin moisturizing and repairing, Sodium Hyaluronate has synergistic effect in whitening and freckle removing skin care products.
 
Because the capillaries of human face are extremely fine, it is easy to cause stasis.Blood stasis occurs, and red blood filament appears. After a long time, the original red becomes black, and then spots are formed.At the same time, because of the obstruction of capillary lumen, the skin cells can not get the nutrients such as oxygen, water, vitamins, and various active enzymes in the blood, the cells will gradually shrink and become smaller, lose their activity, like a deflated balloon, lose their original luster and brightness.The skin will become dry, rough, dull and saggy, with wrinkles, pouches, spots, loss of elasticity and luster, and gradually aging.Sodium Hyaluronate has biological activity, which can improve the permeability of capillaries, improve the blood circulation of capillaries, activate blood circulation and remove blood stasis, quickly remove spots and whiten the skin.
