On the effect of glycolic acid on axillary pigmentation
In recent times, many people have been trapped in the disturbance of axillary pigmentation. This disease is not only unsightly, but also often causes people to worry. In the search for solutions to this disease, glycolic acid has gradually entered the public's field of vision.

Glycolic acid is an alpha-hydroxy acid, with small molecules and strong permeability, which can travel smoothly into the deep layers of the skin. Its mechanism of action is very delicate. First, it can accelerate the metabolism of stratum corneum cells. The stratum corneum is also the barrier of the skin, but if its metabolism is slow, it is easy to cause pigmentation. Glycolic acid can promote its renewal, so that the old pigmented keratinocytes are quickly separated, and the new tender cells are replaced, so that the pigmentation trend gradually slows down. Second, glycolic acid can inhibit the activity of tyrosinase. Tyrosinase is a key enzyme in melanin production. If its activity is produced, melanin production will decrease, and skin color will become uniform.

If glycolic acid is used to treat axillary pigmentation, the usage is also exquisite. When using it for the first time, the concentration should be low to prevent skin intolerance. You can take an appropriate amount of low-concentration glycolic acid solution first, gently apply it to the armpit, and massage it for a while to help it absorb. At first, there may be a slight tingling sensation, which is a sign of skin adaptation. If the tingling sensation is too strong, it needs to be stopped temporarily. When the skin gradually adapts, you can increase the concentration or frequency of use depending on the situation. And during the use period, you need to be careful with sun protection, because the skin is more sensitive to light at this time, if exposed to the hot sun, it is easy to cause aggravation of pigmentation.

Looking at people who use glycolic acid, it is more effective. The skin tone of the armpits is gradually lighter, and the appearance of uneven pigmentation is greatly changed. However, there are differences in individuals, and the effect may vary. Some people have sensitive skin, and they may have allergies to it, such as redness, itching, etc. In this case, wash off with water as soon as possible, stop and consult a doctor.

In short, glycolic acid is an effective method for the disease of axillary pigmentation. However, those who use it should be cautious. According to the nature of the skin, follow the correct method to achieve the desired effect and return the armpit skin to a uniform state.
