This specialist non-surgical treatment is carried out using anti-wrinkle injections (Botox) to weaken the masseter muscle and reduce the muscle size over time. It really does exactly what it says—thins your jawline to give you a slimmer looking face.
To better understand how this works, imagine you have been lifting weights for a while, then you stop for a few months. There is a very high likelihood you will lose some muscle mass. The jaw slimming treatment works in a very similar way. What Botox does is relax the masseter muscles for, typically, 3-4 months. When relaxed this facial muscle becomes less active and just like any other muscle in your body, it’s bound to reduce in size.
However, this a gradual procedure. After your treatment, results can start being seen from the second week, but optimal results will be visible after 6-8 weeks. Once the treatment has been completed, you will find that the angle of your jaw will relax changing from a strong squares shaped jawline to a more feminine looking oval or heart-shaped face. Botox wears off after a while, so the treatment needs to be repeated every 3-6 months.
