Here are other ways to get prettier while you sleep.
Sleep on a satin or silk pillowcase.
These fibers will keep you from waking up with a bird's nest on top of your head, and their texture softens wrinkles and fine lines because it causes less friction between your skin and the pillowcase.
Change your pillowcases often.
Wash your pillowcases frequently so you’re not resting your lovely skin on top of bacteria nests for eight hours a night. Change your pillowcases twice a week, and flip your pillows over on days you're not changing them.
Sleep with a humidifier on.
You probably already know that drinking tons of water is good for your skin, but since you can't do that in your sleep, try using a humidifier to keep yourself hydrated at night. This is especially helpful during the winter, when your skin tends to be much drier.
Go to bed with a clean face.
Going to sleep with your makeup still on causes you to wake up with eye gunk in the morning. It also causes clogged pores which lead to breakouts.
