On the effect of glycolic acid on dark spots
Skin care people in the world have doubts about the effect of glycolic acid on dark spots. Glycolic acid, a type of fruit acid, is often used in skin care products to improve skin conditions. However, its effect on dark spots needs to be reviewed in detail.

Glycolic acid has the ability to exfoliate, which can make the old keratin on the surface of the skin fall off and promote skin metabolism. When used for the first time, there may be redness and slight itching of the skin, which is a sign of skin adaptation. If the skin is well tolerated and used continuously, it may make the skin smoother and more delicate.

As for dark spots, the causes are complicated, or due to sun exposure, endocrine disorders, post-inflammatory pigmentation, etc. It is said that glycolic acid can cause dark spots to worsen, because the skin is stimulated by glycolic acid, or trigger an inflammatory response. If the skin inflammation intensifies, melanocytes may be stimulated to secrete more melanin, causing the color of dark spots to deepen and the range to expand.

However, there are also different opinions. If used properly, glycolic acid can help remove the keratin accumulated on the surface of dark spots, make the skin absorb whitening ingredients better, and its metabolism-promoting effect may help melanin excrete from the body, thereby reducing dark spots.

Those who want to use glycolic acid to improve dark spots should be cautious. Try it before the local skin to see if it is uncomfortable. And in the process of use, be sure to do a good job of sun protection, because the skin is more sensitive to ultraviolet rays after being treated with glycolic acid. If the dark spots do not improve and worsen after using glycolic acid, stop using them immediately and consult a professional dermatologist to find a more suitable way. In short, the effect of glycolic acid on dark spots, your mileage may vary, only use it cautiously, can you get good skin care effect.
