The sodium hyaluronate contained in chamomile's soothing repair lotion is an inherent component of human body. It is a glucuronic acid, and has no specific species. It is widely distributed in placenta, amniotic fluid, lens, articular cartilage, dermal dermis and other tissues. It distributes in fine cytoplasm and intercellular substance, and plays a role of lubrication and nourishment in the cells and cell organs contained therein.
Sodium hyaluronate has the following functions:
1. To improve the efficacy of HA is the main component of connective tissue, such as human intercellular substance, eye vitreous, joint synovial fluid, etc. it has the characteristics of keeping water in vivo, maintaining extracellular space, regulating osmotic pressure, lubricating and promoting cell repair. As the carrier of ophthalmic drugs, it can increase the viscosity of eye drops, prolong the retention time of drugs on the eye surface, improve the bioavailability of drugs, and reduce the irritation of drugs to the eyes.
Adjuvant therapy can be directly injected into the articular cavity as a lubricant for the treatment of arthritis. The moisturizing function of sodium hyaluronate in skin tissue is one of its most important physiological functions. Sufficient water makes skin smooth and delicate. Ha has the highest moisture absorption under low relative humidity (33%) and the lowest moisture absorption under high relative humidity (75%). It is suitable for the skin's moisturizing needs under different seasons and environmental humidity, and has no greasy feeling and the feeling of blocking pores.
2. The moisture level of anti wrinkle skin is closely related to the content of hyaluronic acid. With the increase of age, the content of hyaluronic acid in the skin decreases, which weakens the skin's water holding function and produces wrinkles. Sodium hyaluronate aqueous solution has strong viscoelasticity and lubricity. When applied on the skin surface, it can form a layer of moisturizing and ventilating film, which can keep the skin moist and bright. Small molecule hyaluronic acid can penetrate into the dermis, promote blood microcirculation, facilitate the absorption of nutrients by the skin, and play the role of beauty and anti wrinkle health care.
Film forming and lubricity It belongs to high molecular polymer. When applied, it has obvious lubrication and good hand feeling. The macromolecules form a layer of breathable film on the skin surface, making the skin smooth and moist, and preventing the invasion of foreign bacteria and dust. The small molecule sodium hyaluronate can penetrate into the dermis, with slight expansion of capillary blood tube, increasing blood circulation, improving intermediate metabolism, promoting nutrition absorption of the skin, so as to achieve lubrication and fullness Full effect.
Sun protection and skin damage repair can eliminate the active oxygen free radicals produced by ultraviolet radiation in the sun on the skin surface, protect the skin from UV damage, and also promote the proliferation and differentiation of epidermal cells, promote the regeneration of the injured skin.
3. Compared with these humectants, the moisture absorption of sodium hyaluronate is the highest at low relative humidity (33%), and the lowest at high relative humidity (75%). This unique property is suitable for the skin in different seasons, different environmental humidity, such as dry winter and wet summer, the moisturizing effect of cosmetics. The moisture retention of sodium hyaluronate is related to its quality. The higher the quality, the better the moisture retention. Sodium hyaluronate, as a humectant, is seldom used alone and often used in combination with other humectants.
4. Nutrition sodium hyaluronate is the inherent biological substance of skin. Exogenous sodium hyaluronate is the supplement of endogenous sodium hyaluronate. The sodium hyaluronate of smaller quality can penetrate into the skin epidermis, promote the supply of skin nutrition and the excretion of waste, so as to prevent skin aging and play the role of beauty and beauty. Skin care is more important than other make-up, which has become the modern people's sense of beauty.
5. Repair and prevention of skin damage the skin is burned or sunburned by sunlight, 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 the injured skin by promoting the proliferation and differentiation of epidermal cells, as well as scavenging oxygen free radicals. The mechanism of action is different from that of UV absorbers commonly used in sunscreen. Therefore, HA and UV absorbers are used together in sunscreen skin care products, which can reduce the penetration of UV and repair the skin damage caused by a small amount of UV at the same time, playing a dual protective role.
The combination of sodium hyaluronate, EGF and heparin can accelerate the regeneration of epidermal cells and make the skin tender, smooth and elastic. When the skin suffers from slight burns, the application of water cosmetics containing sodium hyaluronate on the surface can reduce the pain and accelerate the healing of the injured skin.
6. Lubricity and film-forming sodium hyaluronate belong to polymer, which has strong sense of lubrication and film-forming. The skin care products containing sodium hyaluronate have obvious lubrication and good hand feel when applied. After being applied to the skin, a thin film can be formed on the surface of the skin, which can make the skin have a good sense of smoothness and moisture, and play a protective role on the skin. Hair care products containing sodium hyaluronate can form a film on the surface of hair, which can moisturize, lubricate, protect hair, eliminate static electricity, etc., making hair easy to comb, elegant and natural.
