jaw line contouring

Jaw Line Contouring (Reduction) is available at our clinic in Richmond Hill.

The human face has an overall shape of an inverted triangle.  From a traditional culture point of view, a face which is closer in shape to a square than to a triangle, is considered more masculine and is not viewed as aesthetically pleasing in women.

There are many factors which may contribute to the contour of the lower face. In many cases the bulkiness of the masseteric (chewing) muscles is the leading cause of lower face squaring.

What are the traditional treatment methods?

Reconstructive surgery is a way plastic surgeons approach this condition. It involves removing part of mandible bone and/or part of masseteric muscle. Facial implants can also be used to define the shape of the face.

As with any surgery, removal of part of mandible and masseter involve anaesthesia, require some recovery time and carry risks of potential complications.

Dr. Robertus Solution.

Dr. Robertus Jaw Line Contouring or Reduction is a procedure for people who wish to improve appearance of lower face without going through surgical intervention. Injections of muscle-relaxing medication are done into masseter muscles to achieve reduction of muscle's volume and to create a pleasing jaw line with a narrower lower facial width.

At our clinic jaw line reduction treatment will take only 15-20 minutes without any down time for you. You will be able to resume your regular activities immediately. The procedure is quick and done with minimal discomfort.

How does it work?

Injections of small doses of purified protein done into masseter muscles gradually relaxes these muscles by blocking nerve impulses.  This makes masseter muscle working less and the total thickness of the muscle reduces over time, giving lower face slimmer and more pleasing look.

When the results are seen? How many treatments are needed?

Typically, you will notice your face shape change starting from the 6th week after treatment. The change must be more prominent at 3 - 6 months.  The effect can last for up to 1 year.  Repeated injections may be needed - usually, at least two injection treatments are performed.

Will this work for everyone?

Jaw line reduction injections work best for people with prominent and thick masseter muscles.  For those people, who have square face mostly because of underlying bone structure or sagging skin, another treatment techniques will be a better choice.  Also, note that the effect of injections is not permanent and increased use of the muscle after the injection effect is gone may lead muscle to return to its previous shape.  To determine if you will benefit from  Dr. Robertus jaw line contouring we advise to book an assessment appointment with a physician at our clinic, during which, we can discuss the best treatment options for you.

What to do and expect after injections?

Following the procedure you

  • must avoid touching and should not massage injection points for 24 hours;
  • must stay upright for 4 hours;
  • must not take hot bath, showers or be in sauna for 24 hours;
  • you can use make-up in 1 hour after injections.

You will see the medication working in 2 to 4 days after injections with peak of effect in about 2 weeks. With time, the medication will loose its strength and muscles will gradually regain their ability to contract at full strength. Generally, effect of injection lasts for about 4 months.
