The Oh K! Exfoliating Peeling Foot Gel Mask ($13) is by no means a quick fix for your human hoofs, but it is damn fun to use. To set it up, pour the essence into the plastic "socks" provided, then marinate your feet in the slippers for an hour. (I like to use these bad boys while watching my true crime stories, because the white plastic covering makes me feel like I'm a CSI).
You won't notice anything upon taking them off, but in four days, your skin will start to crack and fall off in a grossly satisfying way that reveals brand spankin' new foot skin.
