We all know a good night's sleep aids beauty, but now iVillage has discovered a product promising to remove wrinkles while you sleep.  Under its web-page "Stuff We Love" it highlights US company Cupron, manufacturer of towels, sheets, pillowcases and socks.  It has just created a 'super pillow' said to rejuvenate skin within the first four weeks of use.

The idea is that natural copper heals, and this pillowcase harnessed with that power, will prevent wrinkles and improve your skin's overall appearance while you sleep.  Talk about a beauty nap!
