On the truth about the whitening of glycolic acid

In recent times, skin care has gradually become more and more important to everyone. Glycolic acid has also attracted much attention in the field of skin care. However, whether it has a whitening effect is subject to various opinions. Now it is time to discuss in detail.

Glycolic acid is a type of fruit acid, and its molecules are tiny and can quickly penetrate the surface of the skin.

Glycolic acid makes the old keratin fall off, the skin seems to be reborn, and the color will brighten.

And glycolic acid can increase the metabolism of the skin. If the metabolism is smooth, the generation and transport of melanin may be affected. Melanin is the key to dark skin tone. If its generation or transport slows down, the skin tone can become lighter. The second is also.

The skin barrier is damaged, or the skin may be sensitive, dry, or even red, swollen and tingling. At this time, the skin cannot take care of itself, let alone whitening. Second, melanin generation is regulated by a variety of factors. Although glycolic acid can affect some links, it is difficult to fully control melanin generation. If ultraviolet rays are strongly irradiated, melanocytes can still produce a large amount of melanin. At this time, only glycolic acid is relied on, and the whitening effect may not be obvious.

Therefore, those who want to use glycolic acid to whiten should be cautious. Try it on a small area of skin first to see if there is any discomfort. And use it to a certain extent, adjust the frequency and concentration according to the skin's tolerance.
