According to certified SkinSpirit aesthetician Wanda Chandler, retinol also “clears acne and reduces the appearance of sun damage and pigmentation,” essentially making it a one-stop shop for all skin concerns. It’s important to note that retinol shouldn’t always be used alongside other exfoliators in your skin-care regimen, including AHAs and BHAs, so if you use those, alternate them with the days you use retinol. “Please keep in mind that retinol is another form of exfoliation, and excessive use of it can lead to more sebum production—which can create more acne on the skin,” says Chandler.
