There is no need of expert knowledge to apply blush. Here are some simple tips to apply blush correctly for different face shapes.
1. Long Face
Apply pigment in a circle, on the apples of the cheeks or just above them. If your formula has shimmer, take care to keep the luminosity on the highest point of the cheekbones to give a lifted effect.
2. Round Face
Place color diagonally, following a line from the side of the mouth to ear and blend—like a permanent smile—to accentuate the area. Most important, choose a matte formula, because shine can make a round face look even rounder.
3. Square Face
Play against an angular jaw by sweeping a rounded shape just below your cheekbones, blending out. This will bring the focus up to the width around the cheeks, not the jaw.
