Highlighter (or illuminator) is makeup that attracts light and is used alongside contouring. Apply it to your cheekbones, the tip of your nose and down the centre of your forehead. It can also be used to enhance your makeup look by applying it to the inner corners of your eyes, your brow bones, your cupid's bow (the dip above your lip) and the centre of your chin.

A few other recommendations from us would be to use liquid highlighter with liquid foundation and powder highlighter with powder foundation. To help we have tagged our products as either #liquid or #powder so you don't have to waste time finding the right product for you.
