Brighten up with liner

You know to line your top lid, but when’s the last time you took an eyeliner to your lower lash line? "Lining the lower lid with a lighter shade gives you an instant eye-opening effect," says Stern.

Good news: You don’t have to stress over pairing the right shades, thanks to new dual-ended liners that do the color matching for you. Try an eye pencil with a bright color on one side and white on the other. "Highlighting [the lower lash line] area with white brightens your eyes," says Stern.
