On the synergistic application of glycolic acid and nicotinamide
The beauty of the husband's skin is related to the glory of the face. To rejuvenate the skin, the combination of glycolic acid and nicotinamide is actually a method that can be studied in the way of skin care.

Glycolic acid belongs to alpha-hydroxy acids, and its molecules are tiny, which can travel unimpeded and penetrate into the stratum corneum of the skin. With this characteristic, the "bonding" between the keratinocytes can be loosened, so that the old and waste keratin can fall off in an orderly manner, just like the spring breeze blowing away dead branches, and the surface of the skin will be smooth. And it can stimulate the metabolism of the skin, which is like an engine that stimulates vitality, accelerating the renewal of the underlying cells, and the skin will gradually become shiny, like a pearl du

Niacinamide is also a good skin care product. It can effectively regulate the transport of melanin in the skin. If the gate controls the flow, it inhibits its migration to the surface, thus achieving whitening effect. At the same time, niacinamide can strengthen the skin barrier, just like strengthening the city wall, improving the skin's ability to resist external invasion, maintaining skin moisture balance, and keeping the skin moisturized at all times.

When glycolic acid and niacinamide are used in combination, they complement each other. Glycolic acid opens the door to skin renewal and paves the way for the in-depth effect of niacinamide. Niacinamide helps maintain skin stability and enhances whitening and moisturizing effects when the skin is renewed. However, when using both, it is also necessary to be cautious. Glycolic acid is irritating to a certain extent, and niacinamide may cause intolerance to some people's skin. Therefore, when using it for the first time, it should be tried in a small range and at a low concentration. After the skin adapts, the dosage and frequency should be gradually adjusted.

In general, the synergistic use of glycolic acid and niacinamide, if properly prepared and operated cautiously, can bring multiple benefits to the skin such as rejuvenation, whitening and stability maintenance. It is a wonderful way of skin care, but it needs to be done step by step according to the individual skin type to achieve the ideal skin care effect.
