Answer: If you have a round face shape or are after an instant lift, you can create an elongated look by applying the blush on the cheekbones, pulling it up and out toward the temples. To define your face even further, top off with bronzer on the hallows of the cheeks and right under the jawbone.
If you have a long or oval face shape, apply the blush just under the apples of the cheeks to add dimension and the illusion of roundness. You can also emphasise bone structure and square out your face by applying blush right below the apples of the cheeks, blending it up and out.
