To prevent wrinkles get into the habit of sleeping on your back. Think about it. Look at your face in the mirror. See what side has the wrinkles. I bet the smoother side is the side you sleep on. Interesting how something as small as how you sleep makes your face look older.
Those of us that are older, meaning over 30, look at your friends faces. I would try this test. Of course the older the friend the more evident it is which side they sleep on. They have had years of practice. Then tell your friend what side of the body they sleep on. You will shock them. Look at their face and look for the side of the face that is smoother and that is the side they sleep on. Be careful and not to insult this person by suggesting they have large creases in their face. Some people are a little sensitive about this. This practice can cause some awkward moments. I know I would feel weird if someone walked up to me and told me I had wrinkles on my face and it was because I was sleeping wrong. So be cautious when approaching a person to have this discussion. It could get lively and that is putting it mildly.
