If you have a long, oval face like Jessica Alba's (lucky you), your blush endgame is to create a wider shape to open up the face and make it look fuller and softer.

"Start at the apples of the cheeks, and blend the color out toward your ears in a horizontal shape," says Bhatty. But if your blush starts to look like a football player's eye black, you've gone too far. Make sure to blend out your color with a big fluffy brush like the Charlotte Tilbury Bronzer Brush to avoid a stripey appearance. "Also, watch out for sculpting too much along your cheekbones, because that can make a long face look too angular."

Women with heart-shaped faces walk a risky line when applying blush. Done the wrong way, you could end up exaggerating your pointed chin to the effect of the evil queen in "Snow White." But you also don't want to pile blush on the apples of your fuller cheeks. Bhatty suggests placing your fingers over your cheekbones, and applying the blush just a smidge under that area. "You want a sculpted effect similar to contouring. This is going to bring the focus away from the bottom of the face and back to the cheekbones."

"With heart-shaped faces in particular, the traditional way of applying blush [from the apples to the hairline] will make a V-shape, which will really exaggerate the chin area.
