"On whether glycolic acid can make the underarm black"

The effect of glycolic acid on the underarm is different. Today explore the reason why it makes the underarm black.

Glycolic acid has the power of exfoliation, which can make the old keratin on the surface of the skin fall off and rejuvenate the skin. However, if used improperly, it may cause abnormal underarm skin.

First, the underarm skin is delicate, if the concentration of glycolic acid is high, and it is used frequently, or it may overstimulate the skin. The skin is stimulated by this, in order to protect itself, melanocytes may be active, and melanin production increases, which then makes the underarm black.

Second, individuals have different tolerances to glycolic acid. Some people have sensitive skin, and even normal concentrations of glycolic acid may cause discomfort and cause local inflammation. Pigmentation after inflammation is also the cause of underarm darkening.

If you want to use glycolic acid to care for underarm skin, you should first test it on a small area of skin to observe its reaction. And according to your own skin type, adjust the frequency and concentration of use appropriately. If you have seen underarm darkening, you should stop using it immediately, seek medical attention as appropriate, or take a gentle whitening repair method to restore the primary color of the skin. In this way, it can be used reasonably to avoid skin damage.
