Through the use of makeup, specifically highlighting and shading, the apparent shape of an actor's face can be changed. By highlighting the face's protruding bones, the features become pronounced; shadowing cavities can add depth. Sagging jowls, forehead wrinkles, eye pouches, and prominent veins can be created by manipulating highlights and shadows. A highlight is a base makeup that is at least two shades lighter than the base. It is applied on the bridge of the nose, cheekbones, and areas under the eyes and below the brows. Using a color two shades deeper than the base provides depth and definition. This depth is commonly used on the eye sockets, to thin the sides of the nose, to shallow the cheeks, and to minimize heaviness under the chin.
