Glycolic acid can promote epidermal cell renewal, accelerate melanin metabolism, and normalize the color of dull acne scars.

And glycolic acid can improve the permeability of the skin, making subsequent skin care ingredients easier to absorb. This is like opening a convenient door for nutrients, helping other beneficial substances penetrate into the bottom layer of the skin, synergistic effect, and enhancing the repair effect of acne scars. However, when using glycolic acid, it should be moderately used according to the skin's tolerance. If the dosage is excessive, it may cause skin redness, tingling and other discomforts. For beginners, it is recommended to try it on a small scale first, and then gradually increase the scope and frequency of use after the skin adapts. In this way, the power of glycolic acid can be used to gradually heal acne scars and make the skin smooth.
