However, the application of vitamin C to health and beauty formulations faces many challenges. Heat, oxidation, reaction with metal ions and other commonly used ingredients in cosmetics can easily make vitamin C lose its biological activity. This will cause its ingredients to lose their role in cosmetic formulations and severely reduce their efficacy. To solve this problem, Hayashibara of Japan collaborated with a well-known chemist to synthesize a new substance from vitamin C and glucose with a new type of enzyme preparation.

This substance forms a special stable vitamin C (Ascorbyl glucoside) called L-Ascorbic Acid 2-Glucoside. This vitamin C derivative, referred to as AA2G, has excellent formula stability, can essentially inhibit discoloration and degradation, while retaining all biological activities to achieve brightening and whitening, resistance to ultraviolet radiation, and anti-aging effects.

Vitamin C is a naturally occurring antioxidant and an important component of the skin. It plays an important role in preventing dry skin, skin collagen synthesis, and skin renewal. It exists in all layers of the skin but is more concentrated in the epidermis than in the dermis. Studies have found that when the skin is exposed to ultraviolet light, the content of vitamin C in the skin will decrease by about 2/3.

Adding vitamin C to the skin is an effective way to increase the content of collagen, and it also improves the contraction and natural elasticity of collagen fibers. By applying vitamin C to the skin, the collagen structure will be strengthened, and you will get firmer skin. The use of vitamin C on the skin can effectively reduce fine lines and wrinkles. There is also evidence that it can heal sunburn and relieve hyperpigmented areas.

AA2G is hydrolyzed under the action of alpha-glucosidase, which is found in the cell membrane of skin cells. This process releases vitamin C in a form of high biological activity. When vitamin C enters the cell, it starts to play its obvious and already widely proven biological response. The hydrolysis of AA2G is a continuous process that will have a continuous and stable physiological effect on the skin. The discoloration resistance of AA2G is reflected in the entire production and storage process of cosmetics. This characteristic of AA2G can help it improve the stability of product quality.

In short, vitamin C can make the skin tone more even, make the skin radiant, stimulate collagen synthesis, and combat skin aging. Pure vitamin C is still an important ingredient in skin care, but its derivatives usually produce better results. They are more stable, more affordable, and less irritating. Some derivatives are as effective as pure vitamin C in increasing skin collagen synthesis. On the other hand, if you want to stimulate collagen synthesis and exfoliation at the same time, pure vitamin C is a better choice.
