How is that possible? When sleeping on the face, what happen is that certain facial muscles are compressed for a prolong period of time. It does not matter whether sleeping with or without pillow or purely on mattress, sleeping this way cause the muscles to stretch and contract. This tends not to be a problem when we are still young as the muscles will return to the relax state. However as age catches up the skin loses its elasticity and progressively lose this ability. Eventually, lines start to surface which turns into wrinkles.
