A Doc's Advice: Sleep on silk!
A cosmetic surgeon was asked if sleeping on the stomach also cause wrinkles. The answer is yes for the face is not really that flat on the pillow and sleeping with the head’s weight on it causes the skin to crumple or gets wrinkled. The advice is to therefore use a silk bedding in order to minimize the “crumpling” effect on the skin. Silk is smooth and it prevents the face from getting wrinkled.
