Second, it can strengthen the skin barrier, like a solid city wall, to resist the invasion of the outside world. Third, it regulates the oil secretion of the skin, keeping the skin fresh and not oily.

Glycolic acid belongs to fruit acids. Its molecules are very small, which can penetrate deep into the bottom layer of the skin and promote the renewal of the stratum corneum.

And it can stimulate collagen production, making the skin more elastic, just like new tender skin.
