Description of Ascorbyl Glucoside

Ascorbic acid glucoside, commonly known as vitamin C glycoside, referred to as AA2G, is a stable vitamin C derivative. AA2G maintains the antioxidant physiological properties of vitamin C and has considerable solubility in water and oil. It also has strong light resistance, heat resistance, reducing properties and antioxidant properties, effectively resisting aging. And it can directly discharge the melanin that has been formed in the epidermis to achieve a powerful and rapid whitening effect.

Characteristics and Applications of Ascorbyl Glucoside

Ascorbyl Glucoside has non-reducing activity, is not prone to oxidation reactions, and is particularly stable in aqueous solutions. It has good light resistance and heat resistance and is not easy to decompose under long-term high temperature heating conditions. After Ascorbyl Glucoside acts on the skin, AA-2G enters the skin cell body and is hydrolyzed by α-glucosidase to release free ascorbic acid.

Ascorbyl Glucoside is very hydrophilic and easily soluble in water. The recommended pH in the formula is 6.0~6.5. The formula is easy to use and has good compatibility, so it is widely used in whitening and anti-aging products. However, some people believe that in an environment with pH 6.0~6.5, the C3 hydroxyl group of AA2G will continue to ionize and be easily degraded; and due to its high hydrophilicity, it is not conducive to penetrating the stratum corneum, entering the living cell layer, and entering the skin. It is difficult for glycosidase to hydrolyze vitamin C.

The structure of AA2G is that the hydroxyl hydrogen atom in the active site of ascorbic acid (hydroxyl group with reducing properties) is replaced by a glucose group. Since the hydroxyl group on the active site in the VC molecule is shielded by glucose, experiments have proven that AA2G not only overcomes the instability of VC due to easy oxidation Disadvantages, it has excellent stability in the presence of heat, oxygen and metal ions.

Ascorbyl Glucoside is a natural active substance containing the structure of vitamin C. After acting on the skin, it is converted into prototype VC through the hydrolysis of α-glucosidase, which slowly releases vitamin C and can effectively inhibit melanin and reduce melanin and melanin. The ability to synthesize the intermediate product dopaquinone. Lightens skin color, reduces pigmentation, has skin brightening, anti-oxidation, delays skin aging, and makes skin brighter, healthier and younger. At the same time, some studies have shown that after Ascorbyl Glucoside is converted into VC, it can significantly reduce the free radicals generated by ultraviolet rays in the skin, significantly reduce skin damage, and play a role in protecting the skin in sunscreen products. Currently, AA-2G is obtained through enzymatic methods.

 

Main Functions and Mechanisms of VC-glucoside

Whitening effect

After Ascorbyl Glucoside enters skin cells, it is hydrolyzed by enzymes and converted into vitamin C, which can inhibit the activity of tyrosinase and significantly reduce the formation of melanin. Ascorbyl Glucoside can also use the reducibility of vitamin C to convert dopaquinone into levodopa, thereby reducing skin pigmentation. That is, the melanin that has been formed is accelerated and reversely restored to its original state. Therefore, Ascorbyl Glucoside has an efficient whitening function, and its whitening effect is more obvious and faster than other additives.

Anti-aging benefits

Ascorbyl Glucoside entering the cells will continuously hydrolyze to produce vitamin C, and vitamin C can promote the synthesis of collagen, accelerate the metabolism of skin tissue, prevent skin wrinkles, and increase skin elasticity. At the same time, vitamin C is a water-soluble antioxidant that can remove free radicals in the body and delay skin aging. Promote collagen synthesis, improve wrinkles and rough skin Collagen is a protein that plays an important role in skin structure and protection. Ascorbyl Glucoside is converted into vitamin C and enters skin cells for collagen synthesis in fibroblasts, which has a significant effect on reducing wrinkles and rough skin.

Reduce UV damage

Inhibits cell damage caused by ultraviolet radiation. After Ascorbyl Glucoside is converted into vitamin C, it can significantly reduce the free radicals produced by ultraviolet radiation on the skin, significantly reduce skin damage, and play a role in protecting the skin in sunscreen products。
