Reader Question: What do [K-pop stars] do when they have a surprise pimple on a big day? The easiest remedy I've encountered is stick on pimple patches. (I'm a fan of Hero Cosmetics' Might Patch Invisible+.) Once, I was backstage with Pentagon, and one of the members had a cluster of acne stickers along his jawline. Once he went on stage, you couldn't even see them under the bright lights.
