Yesterday’s forty-minute Tube ride, quietly sweating under your mask as you listened to a podcast. The queue for the checkout in the supermarket. Grabbing a coffee at lunch. When was the last time you washed your mask? You can’t remember. There’s no denying that masks are now an integral part of our everyday lives – I live in fear of leaving mine behind every time I walk out of my front door. However, our skin isn’t such a big fan, with the term “maskne” (that’s mask acne, for the uninitiated) recently joining such gems as “new normal” and “Zoom” in the pandemic vocabulary hall of fame.
