How do jawline slimming injections work?
The bulk of the lower face at the back of the jawline is primarily due to the large paired masseter muscles. The masseter muscles primary role is in chewing food, and in some people can become overdeveloped and overactive.
Overdeveloped masseter muscles can give your face a large, square and boxy appearance. They can also give you headaches, and damage your teeth and TMJ joint from clenching and teeth grinding.
Using muscle slimming injections, the masseter muscles can be relaxed. Once relaxed, the strength will be reduced, and the muscles will reduce in size. As the muscle reduces in size, the lower face and jawline become less prominent at the back, giving the face and jawline a slimmer appearance. You may also notice an improvement in the symptoms of teeth grinding and jaw clenching.
The treatment generally involves 4-5 injections per side using tiny needles. The product is placed into the masseter muscles and will take 2 weeks to relax the muscles, and 6 weeks to slim them.
Jawline slimming results last longer than other muscle relaxing treatments. This is because we are able to inject higher amounts of muscle-relaxing product without increasing the risk of side effects.
How are jawline slimming injections performed?
Jawline slimming injections are a simple treatment to undergo as a patient.
Following your consultation, the skin will be cleaned, and your masseter muscles marked. Marking the skin minimises the risk of affecting the nearby risorius muscle that can weaken your smile.
We then use a very fine needle to precisely place a muscle-relaxing product into the masseter muscles. Each injection takes just a few seconds, and the entire injection process is usually completed in less than 2 minutes.
Once the injections are complete, your skin will be cleaned again, and you’ll be able to resume almost all normal activity immediately.
Benefits of jawline slimming injections
Precise placement of muscle slimming product into the masseter muscles has a number of great benefits that can treat concerns including:
- Slim a square, boxy jawline
- Improve TMJ pain
- Relieve headaches resulting from jaw clenching
- Give the face a more tapered appearance
- Prevent teeth grinding, protecting your teeth and saving you from expensive dental bills
The masseter muscles are located at the back of the jawline and treating them with jawline slimming injections is a very straightforward process.

Biggest risks of jawline slimming injections
Jawline slimming injections are a low-risk treatment, with the most common side effects being slight redness and tenderness that resolve in 1-2 days. The most important side effects from jawline slimming injections are very rare and resolve on their own. These effects are:
Smile weakness occurs when the injected muscle relaxing product inadvertently affects the nearby risorius muscle. It has less than 1% chance of occurence.
Smile weakness can affect one or both sides of the face, and will reduce how much your smile draws outwards. It is usually subtle with only 1-2mm difference in your smile, and will resolve on its own.
Smile weakness can be avoided by ensuring that a 1cm margin is given between the front of the masseter muscle and the injection sites.
Paradoxical bulging occurs when a small amount of the masseter has not been affected by the injected muscle-relaxing product. It has less than 1% chance of occurrence.
When you clench or chew, the unaffected muscle fibres will contract giving the back of the jawline a small bulging appearance. When you relax the bulge will disappear.
Paradoxical bulging is very rare and will resolve on its own. We can also treat it by injecting additional product to the bulge. It can be avoided by using slightly longer needles. This ensures that the product is distributed to all parts of the masseter muscles.
How we reduce your risk of jawline slimming injection side effects?
Here at Cosmetic Connection, we take a landmark-based approach to jawline slimming injections. This reduces the risk of side effects by ensuring that the muscle-relaxing product is injected with high precision.
We always mark our patients, outlining the muscle. We also allow a margin at the front of the muscle to avoid inadvertently treating the risorius muscle. Treating the risorius can temporarily weaken your smile.
Our team also use longer (but very fine) needles to ensure that the product affects the masseter muscle sufficiently, and evenly. Many clinics use short needles designed for injections just beneath the skin. This can cause the product to migrate and affect the risorius muscle, weakening your smile. Shorter needles are also not long enough to reach the deeper masseter muscle fibres, meaning that you have a higher risk of muscle bulging.
