Muscle Relaxing Injections are used to soften a square jaw.

As we age the muscles in the face become stronger and more developed, just like the muscles in your body when training at the gym. The jaw line is an area that is prone to-overdevelopment as we continue to age. Combine this with fat loss in the cheek area and your face can lose its angular shape and become more “square” like.

What does Jaw Line Contouring with Muscle Relaxing Injections involve?

Jaw Line Reshaping or Contouring with Muscle Relaxing Injections is a procedure designed to soften the facial contour of the jaw line giving the face a more youthful and feminine appearance. Men have a squarer jawline while young women have a triangular jawline. The softening and reshaping of the face can also reduce headaches and teeth grinding so patients don’t have to wear a mouthguard at night.

The procedure involves a few injections into the masseter muscle (the strong muscle in the jaw line) and takes about 20 to 30 minutes in most cases. Quite often, we will combine this with Cheek Augmentation, to create the optimal look for our patients. The treatment is only mildly uncomfortable and you will be left with tiny marks like mosquito bites, which will last for a few minutes. Ice is usually used to constrict blood vessels and therefore minimise the chances of bruising.

How long will the results of the Jaw Line Reshaping last?

The results of Jaw Line Reshaping with Muscle Relaxing Injections will become obvious within 10 to 21 days and last 8 to 12 months (Disclaimer – results may vary from patient to patient). Most patients need only one treatment to see the full effect. It is reasonable for patients to expect long-term benefits but not permanent changes.

Is Jaw Line Contouring painful?

The Jaw Line Contouring procedure is a very simple, quick and easy procedure. Ice is used to numb the area if needed, and then tiny Muscle Relaxant Injections are entered into the muscle site of the jaw line (known as masseters). You can continue your normal activities straight away.

How do Muscle Relaxant Injections work to reduce the size of the muscle?

Muscle Relaxant Injections works by reducing the activity of the muscle, which reduces the size of the jawline muscle. It will take 3 weeks to see the full effect (*Results may vary from patient to patient).

Can Muscle Relaxant Injections help to reduce teeth grinding?

Yes, Muscle Relaxant Injections have been shown to reduce teeth grinding activity where other techniques have failed. Teeth grinding can lead to headaches, facial pain and enlarged masseter muscles. A small amount of Muscle Relaxant Injections is all that is required to reduce activity.

When can I get back to normal activities?

Some patients come during their lunch break to perform the jaw line reshaping with Muscle Relaxing Injections and return straight to work or resume normal duties. However, we advise not to massage your face for a few days following the procedure.

Is it safe?

Jaw Line Reshaping with Muscle Relaxing Injections are safe when administered by a medical professional. They have been used for over 25 years in both cosmetic and therapeutic treatments without any reported long-term issues. In fact, Muscle Relaxing Injections are commonly used in higher dosages to treat children with cerebral palsy to reduce muscle spasms, lazy eye and excessive sweating.

What are the possible side effects of Jaw Line Reshaping?

There have been no permanent side effects reported for Jaw Line Reshaping with Muscle Relaxing Injections procedures. Most patients will have regular treatments for many years without ever encountering an issue. After treatment, minor swelling may occur but this is easily covered with make-up if required. Small marks, like mosquito bites, may also appear following treatment but this will only last for a few minutes. If the injection is put in too high it can affect your smile for 2 to 3 months.

Who is a good candidate for Jaw Line Contouring?

Jaw Line Contouring is good for people whose faces appear bulky and bottom-heavy due to strong masseter muscles. It helps to restore a softer and more youthful jaw line appearance. You can assess the strength of your jaw line muscle (masseter) by grinding and placing your fingers over the corner of your jaw.

How much does it cost?

Jaw Line Contouring will usually cost $600 to $900.

The examples, predictions, and results offered on this website vary from individual to individual. Results take time. They can be seen in as little as 6 weeks. This time may vary considerably depending on each individual. 6 weeks is a typical example. Results are effected by a number of factors, predominantly the way in which a patient follows instructions post surgery and the manner in which the patient behaves generally post surgery. Diet and exercise play an important part in the health and well being of a patient and in the maintenance of their body shape. Results will also vary purely based on the general make up of each patient and whether they have had surgery previously.
