What is 

Jaw Slimming

Jaw slimming is a treatment that can soften a prominent square jaw for a more feminine and softer face shape.

There are two key reasons why someone would benefit from jaw slimming.

One, it provides an aesthetic slimming and softening of the jawline, for a tapered oval or heart shape appearance.


And secondly to assist bruxism, a condition characterised by excessive clenching and grinding of the teeth, causing the jaw muscle to enlarge and subsequent tension and pain.

With the use of muscle relaxant we can inject into your Masseter muscle to achieve a result you are after.

What are the masseters?

The Masseters are your mastication muscle or chewing muscle is location on either side of your angle of jaw. A common concern with treatment of the Masseter muscles is the inability to chew or eat after treatment however, the Masseters are 1 of 4 chewing muscles. It is normal to feel a reduction in the ability to chew food and so more chewing is required for foods like meat in the first week or two post treatment.


Who Is It For?

This treatment is great for those that want to soften a square face to achieve a more tapered, slimmer jawline without the need of other invasive treatments*. Or for those with medical conditions such as Bruxism who grind their teeth or for those that clench excessively.

*Individual results may vary


How Long Does Jaw Slimming Results Last?

You can expect to see visible face slimming from 2-6 week of treatment, with the effect designed to last 4 to 8 months*. It is recommended to maintain your jaw shape, that you come in for a consistent treatment as consulted in your treatment plan.
*Individual results may vary


How does it work?

Muscle relaxant is injected on both sides of the face in multiple points in the Masseter muscle to reduce the size of the jaw. The right dose and points are important factors as it determines how effective the jaw muscle slims down for an aesthetic result and relief from tension and pain.

The amount varies and is determined by your medical history, if you suffer from Bruxism, if you are having your first or subsequent injection, or you want to achieve an aesthetic slimming result. Results are not seen straight away and the slimming effects can be seen from 2-6 weeks post treatment. It is quite common to have a top up dose 6 weeks post your initial treatment, to further shrink the muscle down.

With consistent treatments, your muscle will atrophy and shrink overtime and treatments will only be required at longer intervals.

The jaw slimming treatment is a very effective treatment, with no downtime, minimal pain and amazing results.
