On the use of glycolic acid at night
The use of glycolic acid at night has attracted much attention in the way of skin care. However, people often doubt whether it can be used at night.

Glycolic acid has unique properties and belongs to the category of alpha-hydroxy acids. Its molecules are tiny, allowing it to travel smoothly through the skin and penetrate deep into the texture. It can loosen the adhesion between keratinocytes, causing old and waste keratin to fall off, making the skin rejuvenated, smooth and delicate. And it can stimulate collagen regeneration, improve skin quality, and reduce fine lines.

As for the use of glycolic acid at night, it is reasonable. At night, when the skin repairs itself, its metabolism is booming. At this time, using glycolic acid can take advantage of the active state of the skin and exert its effect more efficiently. First, there is less external stimulation at night, and the skin's tolerance to glycolic acid may be enhanced. Second, glycolic acid helps keratin renewal, carried out at night, and the skin can be seen radiant in the morning.

However, when using glycolic acid at night, it is also important to pay attention. For beginners, it is recommended to start from a low concentration, such as 2% - 5%, to make the skin gradually comfortable. And cleanse your face before use, wipe dry and then apply thinly to avoid sensitive areas such as the eye area and lips. If you feel tingling, redness and swelling, you should wash it immediately and suspend use. Furthermore, strict sun protection is required after use, because glycolic acid makes the skin more sensitive to light, and it is easy to cause sunburn and pigmentation during the day.

In short, glycolic acid is used at night, and it is a good skin care policy to make good use of it, which can help the skin achieve a good state. However, be sure to follow the usage according to the skin condition in order to enjoy its benefits and avoid its drawbacks.
