Smearing eye makeup mid-day is a nightmare—and who wants to carry around a touch-up bag? Not me. So, fellow beauty buffs, or those simply in need of a sweat-proof lifesaver, as we enter another grueling day in NYC, try dabbing on Laura Mercier's eye primer before applying makeup. This summer's saving grace, a mere $24, not only boosts the shade of your liner and shadow, but also keeps the color on your lids for the entire day. LM eye primer, you are definitely BRANDED.
