Cosmetics designed to enhance one’s appearance (makeup) can be used to conceal blemishes, enhance one’s natural features (such as the eyebrows and eyelashes), add color to a person’s face and—in the case of more extreme forms of makeup used for performances, fashion shows and people in costume—can be used to change the appearance of the face entirely to resemble a different person, creature or object. Techniques for changing appearance include contouring, which aims to give shape to an area of the face.
