Now that everyone and their grandmother is obsessed with sheet masks, another K-beauty innovation is popping up everywhere: acne patches. Instead of popping and picking your blemishes, slap a pimple patch on top of it. Unlike spot treatments, the sticker won’t leave your skin dry and flaky. Most are small, circular hydrocolloid bandages, meaning they absorb fluid from the pimple, explains Debra Jaliman, a board-certified dermatologist and assistant professor of dermatology at Icahn School of Medicine at Mount Sinai in New York City. You’ll know it’s working because you can see the process happening. The clear patch turns white and expands. After a couple hours (or a night’s sleep), peel it off, and the skin where your zit once was flattens and becomes redness-free. Acne stickers also have the added benefit of blocking you from picking your pimples, says Elizabeth Tanzi, the founder and director of Capital Laser & Skin Care and associate clinical professor in the department of dermatology at the George Washington University Medical Center. (Personally, I’m grateful for that benefit of them alone.) This is key as “picking a pimple increases the inflammation and can slow the healing process down,” Tanzi adds. The chances of scarring and getting an infection rise, too. With all this in mind, I rounded up some of my personal favorite acne patches.
