How can I leave the gym looking fresh?

—Lisa Welsh, Ramsey, N.J.

Bobbi: Don’t apply moisturizer or foundation at the gym—your body needs to cool down before you use any type of lotion, or your makeup won’t last. Just wash your face, dry it, then dot concealer under your eyes and apply mascara and a lip gloss. You’ll have a nice glow from working out, so skip blush. Before you leave the locker room, dab away any sweat or oil with blotting papers ($10, sephora.com).
