On the effect of glycolic acid on dark spots on the body
The dark spots are born in the body, and the patients are often bitter and dull, which is unsightly. In recent times, more studies have been conducted on the effect of glycolic acid on dark spots, which is quite important to physicians and beauty seekers.

Glycolic acid belongs to the class of fruit acids, with small molecules that can quickly penetrate the surface of the skin. Its function in the skin is to promote the metabolism of the cuticle. If the metabolism of the stratum corneum of the skin is slow, melanin is easy to accumulate, resulting in the gradual appearance of dark spots. Glycolic acid can accelerate the shedding of old keratin, make the skin renewed and orderly, melanin is difficult to gather, and the color of dark spots gradually fades.

Furthermore, glycolic acid can stimulate the The skin in dark spots is often sinking due to melanin, resulting in slight structural changes and poor texture. The newly formed collagen can reshape the skin structure, making it firm and smooth, and the appearance of dark spots will also improve.

Another study has shown that glycolic acid may inhibit the activity of tyrosinase. This enzyme is crucial for melanin production. If its activity decreases, melanin synthesis will be less, and the color of dark spots will naturally fade.

Then use glycolic acid to remove dark spots from the body, and it should be cautious. It has a certain irritation, and those with sensitive skin may cause redness, swelling, itching and other discomforts. Therefore, it is advisable to try it on a small scale before use, and choose the appropriate concentration according to the skin type. When starting to use, the concentration should be low, and when the skin adapts, it should be increased as appropriate. When using it, it is also necessary to strictly abide by the principle of sun protection. After covering the skin with glycolic acid, it will be more sensitive to light. If exposed to the sun, it will promote the formation of melanin, and the dark spots will worsen.

In short, glycolic acid may have a good effect on dark spots on the body, but it can be used reasonably and cautiously to achieve the desire of beautifying the skin and removing freckles, and keep the skin healthy.
