What is a Jawline?
The jawline, simply put, is the external appearance of your jaw. The bone structure starts from your chin and extends up to your ears. This angle gives your face a clearly defined shape.

About the jaw
The jaw muscles move the jaw in a complex three-dimensional pathway. Your masseter is the primary muscle that covers the sides of the jaw, just behind the cheeks. This muscle is responsible for opening and closing the mouth. Like any muscle, growth will be seen through exercise and resistance.
