Masseter reduction Botox has become an increasingly popular cosmetic procedure for those wanting to create the impression of a slimmer face. Masseter Botox is a non-invasive and fairly inexpensive treatment that can have medical as well as cosmetic benefits. Read on to find out more about this procedure and to help you decide whether you would be a suitable candidate.

What is Masseter Botox?

Masseter Botox involves injecting Botox into the masseter – the set of muscles that run down your jawline that connect your cheekbone to the lower jawbone. You use these muscles every time you eat or clench your teeth.

When injected, the botulinum toxin that temporarily blocks nerve signals in the masseter helps reduce the size of these muscles and will effectively make the face appear slimmer. This is why it is also known as jaw slimming Botox or jaw reduction Botox.

Besides cosmetic purposes, masseter Botox is sometimes used to treat problems with teeth grinding (bruxism) or clenching as well as symptoms related to temporomandibular joint (TMJ) disorders.

In general, this is fairly a simple procedure involving Botox injections into the masseter muscles on each side of your face. The injections are performed with a fine needle and the injection points are spread out at multiple points along the jawline in order to produce effective facial slimming results.

Since the needles used are very small, pain during the treatment is minimal. As with any needle injection, you might feel a slight stinging sensation, but that’s about as uncomfortable as it gets. Your doctor can also apply a topical numbing cream and/or cooling treatment to reduce any discomfort.

The whole procedure is very quick, only lasting about 10-15 minutes, and patients can typically return to their normal activities straight away.

How Long Does It Take to See Results?

As with any Botox procedure, it will take a little while to see the results. Most patients are able to see the first signs of improvement within 4-7 days, and a visible reduction in their jawline after about 4-6 weeks.

The amount of Botox used varies slightly according to each person, but as a general rule, a Masseter reduction requires about 20-30 units of Botox on each side. Men typically require more Botox than women since they have more muscle volume in this area.

For long term results, your doctor may recommend a series of consecutive treatments spread approximately every 4-6 months.

With time and muscle atrophy (muscle shrinkage), less Botox is needed, and gaps between treatments also increase. The end result is a well-defined contour and a more youthful, V-shaped face.

Post Masseter Reduction Treatment Care

We have already established that it does not require any recovery time. You can go about your day as usual. Nonetheless, there are a few things you should avoid in the first 24 hours following the procedure:

· Do not rub the treated area.

· Avoid placing pressure on the treated area.

· Skip your normal exercise routine for the day; in other words, minimize the movement of the lower facial muscles. Exercise would be too strenuous after jaw slimming Botox.

Why should all the above be avoided? Because too much movement can spread the toxin (from the injections) to other parts of the face. We don't want that.

Bear in mind that the effects of Botox are not permanent. With most people, the results will last three to four months. To maintain the results of your Botox jaw reduction, the treatment will need to be repeated at regular intervals.

· Do not lie down for the next 4 hours after procedures.

Benefits of Masseter Reduction

Apart from jawline slimming, Masseter reduction is also used for the treatment of the following:

Teeth Grinding

Teeth Grinding (bruxism) is usually treated with mouth guards or a change in diet. If you suffer from chronic teeth grinding, Botox injections may be the answer for you. The botulinum toxin helps stop the jaw and teeth from involuntary clenching. With this relaxation, it helps alleviate symptoms like:

· Pain in jaw, neck, and face

· Tooth sensitivity, pain, and damage

· A tight jaw

· Dull headaches

· Earaches

TMJ Pain and Symptoms

TMJ or the temporomandibular joint (TMJ) helps you chew along with the masseter muscles. The TMJ acts as a hinge and connects your lower jaw bone to your skull. Pain can develop in this joint often due to excessive teeth grinding and clenching. Botox injections along the jawline can help eliminate symptoms such as jaw pain, damage to the TMJ, headaches, jaw locking, earaches as well as pain in the jaw or face. It also provides a greater motion range of the jaw.
