Jawline slimming – or masseters reduction for cosmetic purposes – is a simple yet effective procedure that involves the use of muscles relaxers into the large masseter muscles to create a slim and more feminine jawline.

 

The masseter muscles are the muscles that are attached at the angle of your jaw and control all the movements related to chewing food. For some people, strong jaw muscles are part of their normal anatomy. However, for others a square jaw line is the result of a condition called bruxism, which causes excessive teeth grinding or clenching.

​

With overuse from habitual teeth grinding, the masseter muscles become over developed and more pronounced, causing the shape of the lower face to alter and acquire that strong ‘square-jawed’ look (plus other painful and potentially more serious symptoms).

Clenching or grinding teeth is an involuntary movement, which we cannot control and can occur either while awake or asleep. The medical term for unconscious teeth grinding and jaw clenching is bruxism, and many people suffer with it for years without even realising it.

 

Muscle relaxers have been proven to be an innovative treatment option for targeting and treating excessive muscle activity and spasticity. Relaxers can soften the appearance of the jawline, leading to dramatic changes in face shape after regular treatment. A slimmer jawline also results in more prominent cheekbones and chin, which are especially important for women, who typically want high cheekbones and a clean jawline.

​

HOW DOES THE PROCEDURE WORK?

A small amount of the muscle relaxer is injected directly into the masseter muscles on each side of the face and spread out at multiple points within the muscles. This helps the muscles relax, reducing the grinding and the masseters hypertrophy.

Most patients report thinning of the face and jaw as a result of treatment with botulinum toxin, while voluntary movements, such as chewing and facial expressions, are not affected by the procedure.

The procedure is highly effective, with minimal or no pain and absolutely no downtime at all. Face slimming and jaw reduction effect is seen at any time between 2 to 8 weeks.

​

WHAT ARE THE RESULTS OF THIS TREATMENT?

The jawline slimming treatment can transform your face completely. In fact, people can go from having a square and masculine jaw, to a narrow and oval face in a matter of weeks.

Depending on the treatment recommended, you could start to see the results within three weeks. Results typically lasts for three to four months. Sometimes a repeat treatment is needed 4-8 weeks later to ensure the best results, with a follow up six months after that.

 

The results generally improve significantly over the first year of treatment. Finally, as the muscles relax and atrophy over time, less relaxer will be needed and there will be with longer periods between treatments.

Side effects and contraindications

​

Relaxing the masseter muscles is a safe and effective way for treating both the neurogenic and muscular components of bruxism with little downtime and minimal side effects.

The injections are slightly prickly or stingy and take about 5 minutes to complete, after which you can return to your normal activities. Side effects relating to the spread of botulinum toxin far away from the injection site have been reported very rarely.
