Just wondering if it's true that sleeping on a silk/satin (which?) pillow case helps prevent wrinkles? Anyone got one and feels it works?
I'd like to 'train' myself to sleep on my back really cos my face is so squashed and wrinkled in the morning from being buried in my pillow, and these days it doesn't seem to bounce back! 
But thinking I will naturally turn sideways in my sleep, maybe a silk/satin pillowcase is the next best thing?
Any advice....
