Can beauty sleep make you look younger?

Skin makes new collagen when you sleep, which prevents sagging. That’s part of the repair process. More collagen means skin is plumper and less likely to wrinkle.

Only getting 5 hours a night can lead to twice as many fine lines as sleeping 7 would. It also leaves skin drier, which can make lines more visible. When it comes to your beauty routine, sleep may be the closest thing there is to a fountain of youth. Your body repairs itself and recovers while you snooze, and that leads to a long list of benefits for your looks. The key is to get enough shut-eye — 7 to 9 quality hours each night.

If you’re getting fewer than 6 hours, it’s likely affecting your appearance. Start getting 1 to 3 more hours of sleep, and you could see some improvement in as little as a day. Keep it up, and within weeks, people will notice that you’re sleeping better by the way you look.
