Don't try to "contour" your face with darker and lighter shades of blush; that's pro territory. Simply apply regular blush with your face shape in mind.On a round face, place blush from the center of your cheek out along the ridge of your cheekbone, blending upward towards your temples. Dot some on your chin, too.
On a square face, use minimal blush placed on the lower apple of your cheek. Don't sweep it upwards or to the side.
