The position you sleep in can change the way you look - for the worse.

Do you sleep on your side? That could leave you with wrinkles - and worse. 

According to Dr. Dee Anna Glaser, professor of dermatology at St. Louis University, side-sleeping is bad for your skin - and your breasts. She says back-sleeping is the best for beauty sleep because nothing is pushing against your face and the weight of your breasts if fully supported, reducing sagginess. 

If you must sleep on your side, use props. a strategically placed pillow or cushion can provide support and comfort while you sleep. You might also want to consider a satin pillowcase. It’s much friendlier on your skin and hair that a non-slip fabric.
