The following is a classical Chinese article with "Glycolic Acid Before And After Pictures" as the core and direction:

The power of fuglycol acid on the skin is particularly impressive. If you taste it, looking at the images before and after it, the changes are obvious.

At the beginning, everyone's skin may have a dull color, rough but not slippery, and flaws are looming. After using glycolic acid for a few months, the skin gradually changes. Its color turns bright, like the early morning light, radiant and shiny. The rough parts of the past are gradually delicate, like grinding jade, and the texture is gradually uniform. The flaws also gradually disappear, like light clouds scattered in the sky.

Looking at the image before and after, it can be seen that glycol acid is on the skin, which can remove darkness and increase brightness, turn roughness into softness, eliminate flaws and cleanse. It is actually a good agent for skin care.
