Round faces contour beneath the cheekbones in a diagonal toward the mouth corners, with highlight down the center of the forehead and chin to build vertical length. Square faces move that shadow to the jaw corners and temples.
Long faces flip the axis: contour along the hairline and under the chin compresses visible length, while horizontal blush placement adds width. Skip the center-face highlight strip entirely.
