On the response of glycolic acid and uneven skin tone
The skin in the world has uneven skin tone. Investigate the cause, either due to sun exposure, or by the slow metabolism of the skin, resulting in uneven pigmentation, and the face loses its uniform luster.

Glycolic acid has a significant effect on improving uneven skin tone. It is a member of the fruit acid, and its molecules are delicate, allowing it to travel unimpeded and penetrate deep into the surface of the skin. It can gently exfoliate the stratum corneum, causing the old and waste stratum corneum to fall off, and the skin to regain its transparency. The stratum corneum has to be renewed, and the pigment deposition is gradually evacuated, and the uneven skin tone is soothed.

And glycolic acid can stimulate the vitality of the skin's metabolism. If the metabolism is smooth flowing, the imbalance of pigment production can gradually calm down. The pigments produced by melanocytes can be transported and metabolized in an orderly manner, so as not to accumulate too much locally, and the skin tone becomes uniform.

Use glycolic acid when it is used with caution. Because of its certain irritation, the skin is delicate, or it may cause discomfort. When using it for the first time, it is recommended to start from a low concentration and gradually adapt it to the skin. And when using it during the day, be sure to take strict sun protection to prevent the skin from being damaged by ultraviolet rays due to enhanced sensitivity.

In summary, glycolic acid is indeed a good method for improving uneven skin tone, but it is used in a good way to achieve the effect of skin beauty, making skin tone as smooth as the flowers of spring, radiant.
