WHAT ARE SLEEP WRINKLES?
These are sleep lines on the face caused specifically when the skin is deformed due to contact with the pillow while you sleep on your side or stomach.
With age, these pillow wrinkles stop fading away in the morning and become permanent.
Often, the sleep creases form along the lines of existing expression wrinkles, making them deeper and more prominent.
