Contouring is one of those makeup skills that can be very useful and takes a while to perfect. To contour essentially means to define areas in the face such as the jaw as well as the cheekbones. When done correctly, contouring can help create a thinner more sculpted face, some call it plastic surgery without the needles, the late makeup genius Kevyn Aucoin was a master of that. All this depends on one thing, is your face square, rounded or oval? Not all faces need lots of contouring, some are lucky with an enlongated oval shape, so it is best to really study your face in the mirror to determine whether you need it.
Sleek Makeup from the UK has come out with a fantastic contouring kit equipped with a bronze brown-ish powder to create shadows and a highlighter. The lighter powder can be applied in the apple of the cheeks, the temple, the tip of the nose etc. The diagram photo is a pretty good guide to guide you through the process. For myself, I tend to contour my cheeks and highlight my temples to slim my face a bit as it is rounded. At night because I know the light is dim I highlight my temples and apple of cheeks using a cream product (Benefit High Beam is a favourite).
