On the effect of glycolic acid on pigmentation
The disturbance of pigmentation is all bitter. Today I want to study the effect of glycolic acid on pigmentation, so I will study it in detail.

Glycolic acid belongs to the class of fruit acids, whose molecules are tiny and highly permeable. Above the skin, the stratum corneum is the place where it first touches. Glycolic acid can loosen the adhesion between keratinocytes, causing the aging stratum corneum to gradually fall off, the surface of the skin to be renewed, the color becomes uniform, and the appearance of pigmentation is also reduced.

And glycolic acid can stimulate the synthesis of collagen in the dermis. Collagen is also the support structure of the skin. If its production is vigorous, the skin is more elastic, the texture is delicate, and the skin environment where the pigmentation is located can be improved, which is beneficial for the disappearance of pigmentation.

Furthermore, glycolic acid can inhibit the activity of tyrosinase. Tyrosinase is also the key enzyme for melanin production. Its activity is inhibited, the synthesis of melanin is reduced, and the color of pigmentation is gradually lighter.

However, when using glycolic acid, you should also be cautious. Because it is irritating to a certain extent, those with sensitive skin may experience redness, swelling, and tingling. Therefore, when using it for the first time, it is advisable to try it at a low concentration and gradually make the skin suitable. When using it, you should also pay attention to sun protection to avoid ultraviolet stimulation and repeated pigmentation.

In short, glycolic acid does have the ability to improve pigmentation, and it is well used. Only by applying it reasonably according to the characteristics of the skin can the best effect be obtained, and the skin can be clear and even.
