Glycolic Acid: What Does It Do and How Often Should You Use It?
1. What exfoliation means
Glycolic acid is an alpha hydroxy acid used to exfoliate the skin surface and improve the appearance of uneven texture. Frequency depends on the product concentration, format, directions, and your tolerance. It is not a reliable way to remove indented acne scars, and combining it with retinol can increase irritation.
