Contouring is a makeup technique that uses light and dark shades to create the illusion of depth and dimension on the face. It can be used to enhance features, slim down the face, or even correct facial asymmetry.
Asymmetrical faces are very common, and they can be caused by a variety of factors, including genetics, injury, or even just the natural aging process. While there is no way to completely correct facial asymmetry, contouring can be used to create a more balanced and symmetrical appearance.
