Wearing a mask is our new normal but as we cover our mouths and noses to stop COVID-19, some of us are uncovering a new problem maskne, or mask-related acne. Cleveland Clinic dermatologist, Shilpi Khetarpal, MD, said some masks arent very breathable and can trap hot air among other things. To reduce the risk of developing maskne, Dr. Khetarpal recommends wearing a 100-percent cotton mask, which is more breathable. If youre using a medical mask, she recommends changing it each day. Dr. Khetarpal said acne treatments can be irritating and drying, so using a gentle moisturizer at night is a good idea.
