Real question: what did we do before acne patches? I’m talking about those clear hydrocolloid stickers that suck out all the gunk from a zit without drying out the surrounding skin. They first became popular in Korean beauty, after which numerous brands launched their own version. And now you just might be able to get Hero Cosmetics acne patches for free. The brand launched with a bunch of hydrocolloid patches: bigger sizes, clear versions and variety packs. I’ve tried them and they knocked out my pimples without irritating my skin.
