On the Effect of Glycolic Acid on Underarm Pigmentation
In modern times, people often worry about the disturbance of underarm pigmentation and want a good remedy to solve it. Glycolic acid, in the field of skin care, has gradually attracted attention, and its effect on underarm pigmentation has also been explored by everyone.

Glycolic acid is a fruit acid and the like, with small molecules that can quickly penetrate the surface of the skin. Its effect on underarm pigmentation is based on several ends. First, glycolic acid has excellent exfoliation ability, which can relieve the accumulation of old exfoliation. The underarm skin is slightly different from other parts. Daily friction and sweat soaking make the exfoliation easy to accumulate, resulting in a dull complexion. Glycolic acid gradually exfoliates the old keratin, making the skin surface glow and clean again. The pigment also seems to fade with the exfoliation, and the color becomes uniform.

Second, glycolic acid can promote the metabolism of the skin. In the underarm skin cells, it can stimulate the rate of cell renewal, so that new cells can quickly replace the old cells. When the metabolism is smooth, the process of melanogenesis and transport may be adjusted. If melanin is metabolized in an orderly manner and does not accumulate too much, the condition of underarm pigmentation can be slowed down.

Third, glycolic acid may inhibit the activity of tyrosinase. This enzyme is key in the process of melanin synthesis. If its activity is controlled, the amount of melanin produced will decrease. In the underarm skin, if there is less melanin, the degree of pigmentation is also light.

However, when using glycolic acid on the underarm skin, caution is required. The underarm skin is delicate, and glycolic acid has a certain irritation. For initial application, choose a low concentration, and try it on a small scale first to see if the skin tolerates it or not. If the skin feels uncomfortable, redness, tingling, etc., stop immediately. The frequency of use should not be high. After the skin adapts, increase the concentration or frequency as appropriate.

In conclusion, glycolic acid may have an effect on improving underarm pigmentation. When using it, it is necessary to take care of the skin and act prudently according to your own skin condition in order to achieve the best effect without the risk of skin damage.
