Believe it or not, the way you sleep at night can actually make a huge difference on how wrinkles form as you age. People who sleep on their side or stomach develop lines on one side of their face that do not appear on the other because of the imbalance in how their skin rests for so many hours every night. While it may not be your favorite way to cuddle up at the end of the day, sleeping on your back will lessen the effects of wrinkles and ultimately help you stay looking younger for longer.
