On the Application of Glycolic Acid to Underarms
Glycolic acid is mild and has unique chemical properties, and has significant functions in underarm care.

First, it has a good cleaning and deodorizing effect. Underarm sweat glands are well developed, which is easy to breed bacteria and produce peculiar smell. Glycolic acid, with its slightly acidic properties, can adjust the acid-base balance of underarm skin and inhibit the growth and reproduction of bacteria. Its molecular structure can effectively decompose and remove the dirt and oil accumulated in the armpits, keeping the armpits fresh and clean at all times, and the odor naturally dissipates.

Furthermore, glycolic acid helps to improve the texture of underarm skin. Long-term use, it can accelerate the metabolism of the stratum corneum, promote the shedding of aging keratinocytes, and then allow new cells to show up. In this way, the underarm skin will become more delicate, smooth, and no longer rough and dull. At the same time, it can also reduce the phenomenon of keratin thickening caused by friction or other factors, prevent hair follicle blockage, and reduce the chance of skin problems such as underarm folliculitis.

In addition, glycolic acid also has good performance in underarm whitening. It can inhibit tyrosinase activity, reduce melanin production, and then dilute underarm pigmentation. With the gradual reduction of melanin, the underarm skin tone will gradually become even and fair, allowing the skin to return to radiance.

When using glycolic acid in the underarm, you need to be careful. Because of its certain acidity, if the concentration is too high or used improperly, it may irritate the delicate skin under the armpit, causing redness, swelling, tingling and other uncomfortable symptoms. Therefore, first-time users should try it on a small area of skin first, and it can be used normally after confirming that there are no adverse reactions. And the frequency of use also needs to be controlled, not too frequently, to protect the health of the underarm skin.

In short, glycolic acid is widely used in the field of underarm care. As long as it is used reasonably, it will bring many benefits to the underarm skin.
