Best Selling Hyaluronic Acid Sodium Hyaluronate for Skin Care

1. Hyaluronic Acid (Sodium Hyaluronate) Overview

2. Hyaluronic Acid (Sodium Hyaluronate) Source

There are 3 methods to obtain Hyaluronic Acid: microbiological fermentation, animal tissue extraction, chemical synthesis. BFSTAR Hyaluronic Acid comes from microbiological fermentation. In this way, Hyaluronic Acid has high purity and good performance-price ratio.

Method	Technical process	Advantages	Disadvantages
Microbiological fermentation	Use Glucose as carbon source fermentation liquid, and ferment in the medium for 48 hours. After fermentation, filter out mycelium and impurities, then obtain Hyaluronic Acid by alcohol precipitation method.	High purity, raw materials is not restricted, simple operation, low cost.
Animal tissue extraction	Use cockscomb or bovine vitreous body as raw material, degrease and dehydrate with acetone or ethanol, soak and filter with distilled water, and then treat with sodium chloride aqueous solution and chloroform solution. After adding trypsin to obtain the mixture, and finally treat with ion exchange agent, then purify to get Hyaluronic Acid.		Low extraction rate, difficulty in source of raw materials, complex separation process, high cost.
Chemical synthesis	Use natural enzymes for polymerization reaction, use of polysaccharide polymers to synthesize ” Hyaluronic acid oxynitrogen heterocyclopentene derivatives”, then add water to decompose enzyme, get a complex of derivatives and enzyme, remove the enzymes in the 90℃ reaction liquid, then synthesize Hyaluronic Acid.	Low cost.	Low purity.

5. Hyaluronic Acid (Sodium Hyaluronate) Benefits

• Moisturizing

HA has large molecular volume and the molecular weight usually reaches into the millions. In aqueous solution, its molecules is extremely stretch out, and entangle to form a continuous network structure. Water molecules combine with HA molecules through polar bonds and hydrogen bonds in this network. The combination makes HA like a “molecular sponge” that absorbs and retains much more moisture. When the “molecular sponge” which is full of water is applied to the skin surface, it will form a hydration film. So HA has a moisturizing effect on stratum corneum; and it prevents the skin from being dry and exerts a skin care effect.

• Anti-aging

Studies have found that when HA binds to the cell surface, it blocks the release of some enzymes; it reduces free radicals. HA can mainly restrict several enzymes close to the cell membrane. The enzymes produce free radicals and lipid peroxidation. Then it can reduce the inflow of hydroxyl radicals on the cell membrane surface; and it prevents the destruction of cell structure. Thus HA can exert its anti-wrinkles and anti-aging effects. After properly applying a certain amount of HA to the skin, HA can quickly bind to the cell surface. It can timely transmit the external growth signal to the cell, and then directly promote tissue’s proliferation, reconstruction and repair. Also HA promotes the recovery of ECM function.

• Stable emulsification

HA is a polymer biological component with a straight chain structure. It has a strong water-holding capacity; and it is easy to form a dense water-soluble polymeric network structure in water. Therefore, its aqueous solution can maintain high viscosity and elasticity, and has a thickening effect. HA has good compatibility with emulsifiers and surfactants. When its aqueous solution mixes with oil phase cosmetics ingredients, the texture of cream, emulsion can be fine and uniform. And long-term storage will not be stratified and water-permeable. It indicates that HA can promote and stabilize emulsification.

• Nourishing skin

HA has the dual effects of moisturizing and nourishing skin, which is unmatched by other moisturizers. When apply on skin surface, macromolecular HA can rapidly form a permeable hydrated film on skin surface to soften the cuticle by hydration; thereby it increases the absorption and utilization of stratum corneum for the active substance. At the same time, HA becomes an effective medium for the delivery of active ingredients in cosmetics, due to skin’s matrix structure. Low-molecular-weight HA can directly penetrate into the dermis to dilate capillaries, increase blood microcirculation, and improve intermediate metabolism. HA acts as a trans-dermal delivery for other active or nutrient components in the skin. Thereby HA can improve the physiological condition of the skin; and it provides a superior external environment for the synthesis of dermal collagen and elastin. Thus HA enhances the supply of nutrients and then produces a nourishing skin function.

• Antibacterial and anti-inflammation

It has been reported that low molecular weight HA can inhibit the pathogens growth and pathological reactions of rodents. It has an antibacterial and anti-inflammatory effect. Due to the unique water absorption and moisturizing function of macromolecular HA, when applied to the skin surface, it is easy to form a hydrated film. The film effectively prevents the skin from bacteria and blocks bacteria from invading the skin. Indirectly, HA exerts antibacterial and anti-inflammatory effect. In addition, HA binds to proteins in the skin matrix. It exists as a protein complex in the intercellular space to form a gel. The gel can bind the cells together. Thereby HA protects cells from pathogenic bacteria and prevents infection.

8. Hyaluronic Acid (Sodium Hyaluronate) Application and Reference Dosage

HA is the best natural moisturizing ingredient for high-grade cosmetics. It has good compatibility and can be added to almost any cosmetic product. It is mainly used in moisturizing cosmetics, such as lotion, toner, essence, mask, facial cleanser, and cream; it can also be used in shampoos, conditioners, shower gels, lipsticks, etc.

Product	Reference Dosage
Hyaluronic Acid	0.05-0.5%

Attention:

• Anti-wrinkle and sunscreen cosmetics should choose HA with higher molecular weight, and the dosage should be 0.1% to 0.5%. Facial cleanser, mask and other products mainly use the permeability of HA, so the low molecular weight HA should be selected. The dosage is generally around 0.1%.

• Hyaluronic Acid added to cosmetics should be compounded with a certain proportion of macromolecular HA, medium molecular HA and small molecule HA, because skin care product containing only a single molecular weight HA has a limited effect. It cannot exert its optimal moisturizing effect.
• Hyaluronic Acid should not be mixed with benzalkonium chloride, quaternary ammonium salt and other disinfectants into cosmetics, otherwise the product will produce sediment.
