The most common blush mistake I see is women who apply blush in the wrong place. Blush is meant to give your cheeks a healthy looking flush. It should be applied to the apples of your cheeks. To find them, smile. The fleshy part is the apple. Be sure to put the blush on the side of your apple, so your nose doesn’t end up looking red. Then you can blend the blush toward your hair line, if you like.
