If you have a round face:
To refine your face, go for a contour that makes your cheeks stand out. To do this, apply the darkest colour in the hollow part of your cheeks and your jaw to conceal your double-chin if you have one.
If you have a square face:
To soften the features of your face, apply a dark hue to the sides of your forehead as well as to the chin to fade out its sharpness. Apply a light shade at the bottom of the forehead and on the cheekbones to create contrast.
If you have an oval face:
To make your face look longer, apply a dark shade to the root of your hair to create the illusion of a shorter forehead. Go with a light shade in the center of the face to brighten things up.
If you have a rectangular face:
To reduce the width and length of your face, place a dark shade on your temples and jaw and apply a lighter colour to your chin to bring attention to the middle of your face.
