I recently ran 13.1 miles in the Nike Women's Marathon, and this perfect little lip balm — Neutrogena's Revitalizing Lip Balm ($9) — was stashed in my prerace goody bag. Nobody really wants to look too done up when exercising, but this sheer, tinted balm gives you the tiniest boost of color without looking unnatural. SPF 20 shields delicate skin, while a collagen-stimulating complex plumps and moisturizes. The Healthy Blush shade (pictured above) is a personal favorite for a rosy flush, but this balm's also available in five other shades, ranging from toasty caramel to a pretty plum. When a lip balm can make it through miles upon miles of the hills and fog of San Francisco, you know it's a very good thing.
