ISO Certificated Natural Fermentation Hyaluronic Acid Powder
Moisturizing and Nutrition
The stratum corneum of normal human skin contains 10-20% moisture, which has a significant effect on moisturizing the skin, preventing skin aging, and preventing various external stimuli. With age or changes in the environment, when the water content drops below 10%, the skin can appear dry and wrinkled.
Hyaluronic acid can solve the problem of skin dehydration. Because the theoretical water retention value of HA is more than 1000ml/g, it is the key component of water retention in human skin. Compared with traditional moisturizing agents, it not only has a good moisturizing effect, but also has no disadvantages such as greasy feeling and clogging of skin pores.
Hyaluronic acid exists in almost all tissues and body fluids of the body, and more than half of the hyaluronic acid in the body is located in the skin. Hyaluronic acid is an important component of the extracellular matrix between cells and is abundant in the epidermis and dermis. The high viscoelasticity of hyaluronic acid, coupled with the hydrogen bond with water, makes it have a strong water retention effect and is used as an ideal natural moisturizing factor.
The hyaluronic acid aqueous solution has strong viscoelasticity and lubricity. When applied to the skin surface, it can form a moisturizing air film to keep the skin moist and shiny, and at the same time, it can also block the invasion of foreign bacteria and dust. Low-molecular-weight HA can penetrate into the dermis layer of the skin, melt into the skin, improve the ability of the skin to retain moisture, continuously moisturize the skin, slightly expand the capillaries, promote blood microcirculation, and help the skin absorb nutrients. Anti-wrinkle, increase skin Elasticity, Anti-Aging effect of skin.
This is the dual role of HA's moisturizing and nutritional properties, which is unmatched by any other moisturizing agent.
Film Formation, Lubricity and Thickening:
Hyaluronic acid is a high molecular polymer. The aqueous solution has strong viscoelasticity. It can form a moisturizing and breathable film on the skin surface, making the skin have a strong sense of lubrication. The film formed on the surface of the hair is not only moisturizing and lubricating. , can also play a role in eliminating static electricity, making hair easy to comb, elegant and natural. The aqueous solution of hyaluronic acid has a high viscosity and is in the form of a gel. It can thicken and stabilize when added to cosmetics.
Repair of sun protection and skin damage:
In the epidermis, hyaluronic acid can eliminate the active oxygen free radicals generated by ultraviolet radiation in the sun, protect the skin from its damage, and is known as an efficient free radical "scavenger". Because oxygen free radicals can cause lipid peroxidation, damage cell membranes, kill cells, and deepen the skin's pigmentation. Hyaluronic acid reacts with oxygen free radicals, free radicals are scavenged, and hyaluronic acid is degraded. Therefore, hyaluronic acid used in cosmetics can play a role in sun protection. After the skin is exposed to the sun, it becomes red, darkened and peeled, and hyaluronic acid can promote the regeneration of the injured part of the skin by promoting the proliferation and differentiation of epidermal cells. The hydration of hyaluronic acid keeps the water environment of the skin constant and also facilitates wound healing.
In addition, the use of hyaluronic acid on the surface of the skin during pregnancy can reduce the appearance of stretch marks and promote the recovery of postpartum stretch marks.
Hyaluronic acid is an indispensable natural moisturizing ingredient for high-end cosmetics. It can be used in almost all high-end cosmetics. The addition amount is generally 0.05-0.5%.

The difference between high and low molecular hyaluronic acid
High molecular hyaluronic acid:
It is our most commonly used hyaluronic acid. Its molecular weight ranges from 1 million to 1.7 million. It can form a breathable film on the epidermis of the skin, making the skin smooth and moist, and can block the invasion of foreign bacteria, dust and ultraviolet rays. The skin is protected from damage; to put it simply, its film-forming properties are better, that is, its ability to lock water is better, but its absorption by the skin requires lower molecular weights.
Low molecular weight hyaluronic acid:
The molecular weight is below 1 million, generally between 200,000 and 800,000. It can penetrate deep into the dermis, slightly expand capillaries, increase blood circulation, promote metabolism, and improve skin nutrient absorption. That is, it is easily absorbed by the skin, but the water retention capacity is less.
Ultra low molecular weight:
The molecular weight is 3,000-10,000Da, which can be absorbed through the skin and deeply care for the skin; no cytotoxicity, high safety; strong antioxidant activity; easier to absorb, and the skin feels refreshing. It can enter the skin for deep moisturizing. The polymer hyaluronic acid forms a protective film on the skin surface to prevent the evaporation of water inside the skin. The two moisturizing mechanisms are different. When used together, they can play a synergistic effect and achieve better skin care effects.
