On the improvement of glycolic acid on pigmentation
There is a problem of skin pigmentation in the world, and everyone seeks a way to get rid of it. Glycolic acid, in the way of skin maintenance, has attracted much attention, and it is related to the reduction of pigmentation, which has also been explored by everyone.

Glycolic acid, a type of fruit acid, has small molecules and can run smoothly through the stratum corneum of the skin. It acts on the skin, first to loosen the connections between keratinocytes, causing the aging stratum corneum to fall off in an orderly manner, and the surface of the skin to be renewed and uniform in color. This is the basis for reducing pigmentation.

Furthermore, glycolic acid can stimulate the speed of skin metabolism. If the skin's metabolism is smooth, the cycle of melanin production, transport and metabolism will stabilize. Melanin is in the skin. If it is produced in an orderly manner, transported smoothly, and metabolized in a timely manner, the state of pigmentation can be relieved. Due to the speed of metabolism, melanin is difficult to accumulate in one place, so that the color of the skin gradually becomes uniform.

And glycolic acid can promote the synthesis of collagen in the dermis. Collagen is plump and the skin structure is dense, which is also beneficial for improving skin tone. Dense skin has better light reflection, visually shiny skin tone, and weak pigmentation.

Use glycolic acid with caution. Its acidity is irritating to a certain extent, and those with delicate skin may experience discomfort, such as redness and tingling. Therefore, before using it, it is advisable to perform a skin test to know the skin's tolerance before it is appropriate. At the beginning of use, the concentration should be low and gradually increase, giving the skin the opportunity to adapt.

Overall, glycolic acid does have an effect on the reduction of pigmentation. However, users should carefully choose and apply it according to their own skin characteristics, so that they can use its strength to return the skin to a smooth and shiny state.
