The jawline contour is defined by the masseter muscle and the angle of the mandible. Some people have enlarged chewing masseter muscle either because of their genetics or because of their personal habits (chewing gum, bruxism) creating overly square wide jawline.
Injecting Botox into masseter muscles reduces the size of the muscles over time resulting in youthful, oval and more attractive V-shape jawline.
Unlike upper face Botox treatments where results are seen in 10-14 days following treatment and last about 3 to 4 months, it takes about 6 weeks before you can see the difference in masseter muscles treated with Botox and will last typically up to 6 months.
This treatment is very popular nowadays and it can also help with medical conditions such as Bruxism (painful teeth grinding).
