Crow’s feet refer to the fine lines and wrinkles that appear at the outer corners of your eyes. These creases come in two varieties: dynamic and static. According to some, dynamic wrinkles are mostly created by facial expressions. This is because each time someone smiles, they make small creases at the corner of their eyes.
Static wrinkles are the result of natural processes like gravity and age. As we age, our skin loses elastin, a protein found in our skin that helps keep it firm. When it fades away, our skin becomes lax. These proteins are primarily responsible for the plump, firm appearance of the skin.
