On the use of glycolic acid for underarm dullness
People in recent times have many troubles with underarm dullness. To solve this problem, the effect of glycolic acid has been discussed by many people.

Glycolic acid belongs to the class of fruit acids and has unique properties. Its molecules are slender and can travel unimpeded, reaching the deep layers of the skin. It helps the skin's metabolism. It can quietly peel off the old cuticles, making the skin's surface smooth again, like a new life.

As for underarm dullness, the causes are complicated. Or due to excessive daily friction, local skin cuticles accumulate; or due to hormonal changes in the body, melanin production increases. And glycolic acid seems to have potential to improve underarm dullness. Its exfoliating power can slow down the thick accumulation of exfoliation and make the underarm skin delicate again. And it can promote melanin metabolism and make the dull color fade gradually.

It is also prudent to use glycolic acid. Because of its certain irritation, if the skin is already delicate and sensitive, if you use it rashly, you may cause discomfort. It may cause redness, itching, or even molting pain. Therefore, before use, it is advisable to try it on a small part of the skin and observe its reaction. If there is any discomfort, stop using it immediately.

When using it, the frequency also needs to be considered. At the beginning, it should be less sparse, and when the skin gradually adapts, you can increase the frequency. And the protection must not be slack. After daytime use, it is especially necessary to avoid direct sunlight to prevent melanin from regenerating due to light stimulation and causing dullness to return.

In short, glycolic acid is a method for the disease of underarm dullness. Those who use it must carefully examine the nature of the skin, follow the correct method, and be cautious. Only then can they hope to obtain the effect of shiny skin and relieve the worry of underarm dullness.
