Laugh lines
Lines at the outer corners of the eyes and around the mouth that come from years of smiling.
Also: smile lines, crow's feet
Laugh lines are the creases that form where the skin folds most when we smile: the fan of lines at the outer corners of the eyes, often called crow's feet, and the folds from the nose to the mouth. They come with age and sun for everyone. Many people like them as a record of expression, and portrait painters have long used them to show warmth. They are a normal part of a face that has been used.
