Call it a sign of the times: The Korean skin-care brands Dr. Jart+ and Peach & Lily offer collections of “maskne essentials” on their websites. The patch purveyor Hero Cosmetics recently posted an entry about maskne on its blog. But don’t dismiss maskne — acne and irritation from wearing a mask — as just another portmanteau to market skin-care products.
“Oh, it’s a real thing,” said Dr. Mona Gohara, an associate clinical professor of dermatology at Yale School of Medicine. She herself has gotten maskne from her three layers of masks: a KN95 (similar to an N95) topped with a surgical mask to keep it clean, plus a face shield if she’s doing procedures.
