Sleeping Beauty: Sleep Your Way to Better Skin and Hair

Wide-Awake Eyes

The reason you're stuck hauling overnight bags on your a.m. commute: When you're horizontal all night, fluid can pool beneath your eyes.

Before bed, dab on a gel with caffeine, which temporarily tightens skin. We like Vichy Aqualia Antiox Anti-Fatigue Ice Effect Eye Stick ($28, vichyusa.com).
