1.Introduction of Hyaluronic acid Powder:
Sodium hyaluronate is an inherent component of the human body, it is a glucuronic acid, without species specificity, it is widely present in placenta, amniotic fluid, lens, articular cartilage, skin dermis and other tissues; Distributed in the cytoplasm and interstitial cells, it plays a role in lubricating and nourishing the cells and the organs themselves.

2.Function of Hyaluronic acid Powder:
#Improve the efficacy:
HA is the main component of connective tissues such as human cell interstitial, vitreal and synovial fluid. It has the characteristics of exerting water retention in the body, maintaining extracellular space, regulating osmotic pressure, lubrication, and promoting cell repair. As a carrier of ophthalmic drugs, it increases the retention time of the drug on the surface of the eye by increasing the viscosity of the eye drops, improves the bioavailability of the drug, and reduces the irritation of the drug to the eye.
Adjuvant therapy can be directly injected into the joint cavity as a lubricant for the treatment of arthritis . The moisturizing effect of moisturizing sodium hyaluronate in skin tissue is one of its most important physiological functions. Sufficient moisture makes the skin smooth and delicate. HA has the highest moisture absorption at low relative humidity (33%) and the lowest moisture absorption at high relative humidity (75%), which is suitable for skin's moisturizing demand for cosmetics in different seasons and different environmental humidity, without greasy feeling and blockage. The feeling of pores.
* Wrinkle resistance:
The moisture level of the skin is closely related to the hyaluronic acid content. As the age increases, the hyaluronic acid content in the skin decreases, which weakens the skin's water retention function and produces wrinkles. Aqueous sodium hyaluronate solution has strong viscoelasticity and lubricity. When applied on the skin surface, it can form a layer of moisture-permeable and breathable film to keep the skin moisturized and shiny. The small molecule hyaluronic acid can penetrate into the dermis layer, promote blood microcirculation, help the skin to absorb nutrients, and play a role of beauty and anti-wrinkle health.
Film-forming and lubricating properties are macromolecular polymers. When applied, the lubricity is obvious and the hand feels good. The macromolecules form a layer of breathable film on the surface of the skin, making the skin smooth and moist, blocking the invasion of foreign bacteria and dust, and the small molecules hyaluronic. Sodium can penetrate into the dermis, slightly dilate capillaries, increase blood circulation, improve intermediate metabolism, and promote skin nutritional absorption to achieve lubricity and fullness.
Sun protection and skin damage repair function On the skin surface, the active oxygen free radicals generated by ultraviolet radiation in the sun can be eliminated to protect the skin from ultraviolet rays. At the same time, it can promote the proliferation and differentiation of epidermal cells and promote skin regeneration at the injured site.
* Moisturizing effect
Experiments show that compared with these humectants, sodium hyaluronate has the highest moisture absorption at low relative humidity (33%) and the lowest moisture absorption at high relative humidity (75%). This unique property is adapting to the skin's requirements for cosmetic moisturizing effect in different seasons and different environmental humidity, such as dry winter and humid summer. The hygroscopicity of sodium hyaluronate is related to its quality. The higher the quality, the better the moisturizing performance. As a humectant, sodium hyaluronate is rarely used alone and is often used in combination with other humectants.
Sodium hyaluronate is an inherent biological substance of the skin. Exogenous sodium hyaluronate is a supplement to the skin's endogenous sodium hyaluronate. Smaller mass of sodium hyaluronate can penetrate into the epidermal layer of the skin, promote the supply of skin nutrients and the excretion of waste, thereby preventing skin aging and playing a cosmetic and beauty role. Skin care is more important than other makeup, and it has become a modern consciousness of beauty.
Repair and prevention of skin damage
Skin burns or sunburn caused by sun exposure, such as skin redness, blackening, peeling, etc., are mainly the role of ultraviolet rays in the sun. Sodium hyaluronate can promote the proliferation and differentiation of epidermal cells, and scavenge oxygen free radicals, can promote the regeneration of skin at the injured site, and it has a certain preventive effect in advance. Its mechanism of action is different from the UV absorbers commonly used in sunscreens. Therefore, the use of ha and UV absorbers in sunscreen skin care products has a synergistic effect, which can reduce the transmission of ultraviolet rays and the small amount of ultraviolet rays transmitted. Skin damage is repaired and has a dual protective effect .
The combined use of sodium hyaluronate, egf and heparin can accelerate the regeneration of epidermal cells, make the skin delicate and smooth, and full of elasticity. When the skin suffers from a mild burn, applying a water-based cosmetic containing sodium hyaluronate on the surface can alleviate the pain and accelerate the healing of the skin in the injured area.
Lubricity and film formation
Sodium hyaluronate is a high molecular polymer with strong lubricity and film-forming properties. Skin care products containing sodium hyaluronate have obvious lubricity and good feel when applied. After being applied to the skin, a thin film can be formed on the surface of the skin to make the skin feel smooth and moist and protect the skin. Hair care products containing sodium hyaluronate can form a thin film on the surface of the hair to play a role in moisturizing, lubricating, protecting the hair and eliminating static electricity, making the hair easy to comb, flowing and natural.
Sodium hyaluronate has a very high viscosity in aqueous solution, and its 1% aqueous solution is gel-like, which can be added to cosmetics to thicken and stabilize it.
