Firing Off Emails Until the Minute You Go to Bed

How it's aging you: Being hooked on your smartphone or laptop until the wee hours is a recipe for bad sleep. The blue light they emit suppresses the release of melatonin (aka the sleep hormone) in your body, making falling asleep and staying asleep more difficult. And when you're not getting enough sleep, your skin isn't getting the time it needs to repair itself. "Think of nighttime as the time when all the maintenance happens," says Hirsch. "Night is all about restoring and refreshing the skin." And all the anti-aging products in the world won't help if you're not giving them the time they need to work. "We want you to use these products at night not because they're sun sensitive, but because that's when your skin needs them," says Nazarian. If you're regularly skimping on sleep, expect to see more wrinkling because your skin's collagen degrades faster.

The fix: Set a hard cut-off time for work before bed. Most sleep experts recommend going screen-free for at least 30 minutes before lights out. Instead of slogging through your inbox, use that time to relax and get into a sleep-friendly mindset.
