Your jawline is defined by the contrast between your ramus and your neck. If you aren’t born with a naturally wide mandible [lower jaw bone], you can simply develop your masseters muscles and get the same (or even better) effect. This will make your ramus and gonial angle more pronounced and your jawline more defined. Muscles are more attractive than bones, so even if you think that you have a great jawline already, CHISELL will help you knock it out of the park.
