On the feasibility of using glycolic acid on the face
Ordinary people apply glycolic acid to the face, and it must be reviewed in detail. Glycolic acid belongs to the class of fruit acids, which have the power of rejuvenating the skin, can exfoliate, promote metabolism, and enhance luster. However, its strong nature, improper use, can cause skin damage.

First of all, it should show the nature of your own skin. If it is sensitive skin, the stratum corneum is thin, and it is easy to redness, itching and tingling, you should use glycolic acid with caution. Because it may irritate the skin, causing discomfort. For oily and combination skin, if the tolerance is good, you can try low concentrations.

The method of use is also the key. When starting to use, choose the one with low concentration, such as 2% - 5%. Test it behind the ear or on a small piece of facial skin first. After 24-48, if there is no abnormality, it can be used on the face in a small range. And the frequency of use should be thin at first, such as once a week, and then adjust it as the skin tolerates gradually. When using, apply it gently to the face, avoiding sensitive areas such as eyes, lips, and mouth. After applying, you need to wash it with water in time, followed by moisturizing skin care products to prevent dry skin.

If you feel tingling, redness, and itching when using glycolic acid, stop immediately, wash it with water, and seek medical attention as appropriate. In addition, when using it during the day, sunscreen must be added. Because glycolic acid makes the skin more sensitive to light, it is easy to cause sunburn and pigmentation.

In short, when using glycolic acid on the face, caution should be given first. According to the skin's nature and reaction, it can be used reasonably to obtain its benefits and avoid its harm.
