Your most comfortable sleeping state may not be the best for your beauty. "The single biggest reason for accelerated aging of the skin is sleeping on your face," warns Lupo. "The skin is compressed and doesn't get enough circulation, so it breaks down and creases, forming wrinkles."
And if you sleep face down, fluid pools and causes puffiness. Experts recommend sleeping on your back, with two pillows under your head to keep the blood flow moving. If it's too tough to change your sleep position, consider a silk or satin pillow that won't pull at the skin.
