15. Stop Frowning
Remember when your parents used to tell you that if you kept making that face, that it was going to stay that way? Well, it turns out they were right. Over time your facial expressions can create permanent and deep lines in your skin. Frowning has the worse effect on your skin because of how it creates crows feet around your eyes, vertical lines between your eyes, horizontal lines on your forehead, and even creases around your mouth.
