When glycol acid takes effect and application insights
Glycol acid, in the field of skin care, has attracted much attention when it takes effect. This acid acts on the skin, and at first, it may only feel slightly itchy, which is the beginning of its interaction with the stratum corneum. After a short period of time, about a few days to a week, the skin gradually changes subtly, the texture seems to be more delicate, and the color is slightly brightened.

Wait until more than half a month, the effect is more obvious. The pores are quietly narrowed, the dullness is significantly improved, and the meaning of skin rejuvenation is gradually becoming clear. Gein glycol acid can gently loosen the connection between keratinocytes, promote the shedding of old waste keratin, and then accelerate the metabolism of the skin.

When it comes to the application insight of glycolic acid, concentration control is crucial. Low concentration, about 2% - 5%, suitable for first-time tasters, can gradually adapt to this acid, and can also enjoy gentle skin rejuvenation benefits. And high concentration, 10% and above, although the effect is strong, it requires high skin tolerance. Do not try it easily if you are not experienced or have strong skin.

Frequency of use is also key. When using it for the first time, it is advisable to start once a week and adjust it moderately depending on the skin's reaction. If the skin tolerates it well, it can be increased to two to three times a week. However, overuse will cause sensitive and fragile skin, which is counterproductive.

In addition, strict protection is required for daytime use. Because glycolic acid can make the skin more sensitive to ultraviolet rays, applying high-power sunscreen, parasols and other physical sunscreen means is indispensable to keep the skin healthy.
