Bronzer can create a 'sculpted' face – brush lightly down the sides of the nose, into the hollows of the cheeks and under the chin.
Then apply highlighter to catch the light from a flash that creates a glowing skin – on the cheekbones, browbone, collarbone, tips of shoulders and in the cupids bow of the mouth, too.
Finish with a blush that contains iridescent particles to draw light to the cheeks where skin is smoothest. It doesn't matter whether it's cream or powder; just smile and apply to the apples of the cheeks for colour and to catch the light – remember you've already helped define cheekbones with the bronzer.
Cassie says to use a glossy lip colour - instead of a matte finish - for its light-reflecting properties and to go for eyeshadows that contain iridescent sparkle, too, to ensure you shine like a star.
