Face microneedling works wonders for rejuvenating the skin, but you'll need to be careful with what you use on it after each treatment. You'll need to pause your usual skin-care regimen, which includes avoiding supercharged actives such as retinol, retin-A, vitamin C, AHAs, or BHAs. Instead, it's best to stick with a gentle moisturizer that helps speed healing and lots of sunscreen. You'll also want to avoid abrasive exfoliators, cleansers, scrubs, and anything else that can inflame or irritate the skin.
