Besides being a cute reminder to love our skin (even when it's being difficult), turns out these tic-tac-toe essentials are key to hiding a blemish. "With any kind of inflammation from acne, or maybe a mole or a scar, you're dealing with a raised area," Patterson said. Because the skin isn't totally smooth, just dabbing some concealer onto the spot isn't going to be the best way to hide it — and if you've ever tried to conceal one of those huge, sore pimples that never come to a head, you know that struggle. Patterson recommends drawing an X and an O on the blemish, because the O will "hide any redness surrounding the pimple, while the X applies the perfect amount of concealer to it." Ensure that zit stays hidden by adding a light layer of setting powder on top.
