Miranda Kerr always looks beautiful, but last night at an NYC event, she was absolutely radiant. While you can chalk it up to good, clean living, it's also excellent proof that a luminiser can be a girl's best friend. To create Miranda's lit-from-within glow, makeup artist Rose-Marie Swift used her RMS Living Luminizer ($49) multiple ways. First, Swift combined it with concealer to form a glowy base. She then used it as a highlighter on the corners of Miranda's eyes, right at the waterlines by the tear ducts. And to add a finishing touch, Swift applied a bit of luminiser over Miranda's collarbones and shoulders. It really is as easy as that!
