Jawline augmentation is popular among both men and women. This procedure is one of the simplest ways to add definition to the face. In men, it can be used to add a more masculine appearance, and in women, it can be used to help define the jawline and hide sagging jowls. Our jawline serves as the frame for our face and neck. It offers a substantial contribution to our overall aesthetic — even minor changes to the jaw can make a big difference in our overall facial appearance.
