To contour, use the brush to collect a small amount of powder in the tip of the bristles. Tap away any excess to ensure an even colour application. Apply to contour features with light strokes to blend seamlessly.
To highlight, dip the tip of the brush into a powder or cream highlighter; if using a powder, tap the brush handle to shake off any excess product. Sweep the brush wherever you want a touch of radiance. Some good spots to hit are the tops of your cheekbones, the tip of your nose, the Cupid's bow above your mouth, and along your eyelids.
