Sleep wrinkles are simply unfair. You eat right, exercise, avoid excess alcohol and caffeine, and go to bed early. But the next morning, there they are: deep sheet wrinkles in your face and neck, making your face look like badly folded laundry. Side sleeping wrinkles are a particular challenge because the only real way to avoid them is to not sleep on your side. That’s difficult to do, but don’t give up. You can avoid sleeping wrinkles, even if you find sleeping on your back uncomfortably close to coffin rehearsal.
Sleep on your back. Place an extra pillow under your knees to keep you from turning over. You may not last that way the entire night, but any time spent off of your face will help.
Lay a body pillow alongside yourself and rest as much of your weight on it as you can. Use it to prop your shoulder and part of your chest, and throw your leg and hip over it. This will keep your head turned somewhat way from the pillow, keeping a lot of the weight off your face.
Invest in satin pillowcases. The slippery surface will reduce the friction between your face and the pillowcase, helping to stop the bunching of the fabric that causes the deep creases.
