"After battling a cystic pimple for weeks, it finally subsided but left behind an angry red splotch on my left cheek. Twice a week, I slap on one of Hero Cosmetics' Mighty Patch Micropoint for Dark Spots stickers, and the spot visibly diminishes every time. Its dissolvable brightening needles of tranexamic acid, niacinamide, and vitamin C are to thank." — Devon Abelman, beauty editor
