DO: Fake a sun-kissed glow by highlighting your face, cheeks, eyelids and lips with a hue that works for you (like Mariah Carey and Jessica Simpson).

DON'T: Go overboard. "Stay within a shade or two of your natural skin color," says Gage. "You want to look like you've spent a morning in the sun – not a weekend at the beach."
