On the effect of glycolic acid and retinol on dark spots
The disturbance of dark spots on the husband's skin, everyone wants to get rid of it. Today there are glycolic acid and retinol, each of which has its own ability in the treatment of dark spots.

Glycolic acid belongs to the class of fruit acids and is mild in nature. It can dredge pores, exfoliate, remove old and waste exfoliation from the surface of the skin, and gradually expose new skin. The cause of dark spots is related to exfoliation and pigmentation. Glycolic acid can accelerate the metabolism of the skin by its exfoliation power, so that the pigment that has been deposited decreases with exfoliation, and the color of dark spots gradually fades. And it can promote the microcirculation of the skin, make the skin even and radiant.

Retinol is a vitamin A derivative. It has far-reaching effects on the skin, can penetrate deep into the bottom layer of the skin, and regulate cell metabolism. It has the effect of inhibiting the pigment generation process of melanocytes. It can reduce melanin production and promote the transfer of melanin that has been generated to the stratum corneum and fall off. Therefore, retinol can inhibit the formation of dark spots from the source. If used for a long time, the area of dark spots will gradually shrink and the color will be lighter.

However, compared with the two, there are also advantages and disadvantages. Glycolic acid is used for the first time, and the skin may feel slightly tingling and redness, but it can be slowed down after adaptation. Its effect is obvious quickly, and the skin can feel smooth and dark spots are slightly lighter in the short term. When retinol is used for the first time, it may also cause skin irritation, such as dryness and peeling. However, it has good regulation of the deep layer of dark spots, and the effect is even better if it is persisted for a long time.

When using it, it should be selected according to the characteristics of the skin. For dry and sensitive skin, glycolic acid should be selected for the first use, and it should be tried at a low concentration to gradually increase the concentration. For oily and tolerant skin, retinol may be a good choice, but it should also be used from a low concentration and gradually.

In short, glycolic acid and retinol have their own strengths in the treatment of dark spots. Making good use of them and acting according to the skin can help people get rid of the pain of dark spots and get smooth skin.
