On the effect of glycolic acid on brightening skin tone
The ability of glycolic acid to brighten the skin has attracted much attention in recent years. Its mild nature and excellent effect are good agents for skin rejuvenation.

Glycolic acid belongs to the family of fruit acids, and its molecules are small, so it is easy to penetrate into the surface of the skin. Its primary function is to accelerate the metabolism of the stratum corneum. The long-term accumulation of the stratum corneum often causes uneven color and dullness of the skin. Glycolic acid can loosen the connections between the keratinocytes, causing the old keratin to shed in time, allowing new cells to float up, and the skin to appear clear and bright.

Furthermore, glycolic acid can stimulate the production of collagen in the dermis. Collagen is the support pillar of the skin. As you grow older, its production gradually slows down, and the skin sags and loses its color. Glycolic acid activates the activity of related cells, promotes collagen regeneration, fills the skin, improves fine lines, and is also of great benefit to a brighter complexion. The skin structure is dense, the light reflection is more uniform, and the skin tone is naturally even.

In addition, glycolic acid can effectively inhibit the activity of tyrosinase. Tyrosinase is a key enzyme in melanin production. Its activity is inhibited, and melanin production is reduced. In this way, the problem of uneven skin tone such as pigmentation and dullness can be relieved, and the skin gradually brightens.

When using glycolic acid, you should also be cautious. Because of its certain irritation, the initial use should start at a low concentration and pay attention to the skin's reaction. If the skin is sensitive, it should be tested first to ensure safety before routine use.

In summary, glycolic acid does have a significant effect on brightening skin tone, but it should be used reasonably. Only by taking measures for the skin can it be used to achieve smooth and shiny skin.
