My face (jaw especially) is asymmetrical. Would masseter Botox be able to correct this? (Photo)

This can be treated by botox and fillers and should be evaluated in person by a well trained cosmetic dermatologist.  Best, Dr. Emer.

Thank you for your question, Follenack! Botox would be a great option to slim the jawline. Typically, we like to start about 15-20 units per side but this amount may increase depending on the strength of the muscle. Also, one side may need more units than the other due to differences in the muscles. Always consult with an experienced injector before undergoing any procedures.

Thank you for your question. Botox in the masseter region usually takes longer than in the standard areas to take effect. I tend to use anywhere from 15 units (conservative treatment) to 50 units (for someone with really strong masseters) on each side to get the desired result. Different doses can be used in each side to compensate for baseline asymmetry.  It may start within the first week but I tell my patients to wait three weeks before doing a more thorough evaluation. The treatment typically lasts longer than the forehead/crows feet/frown regions. It is also a gradual onset of the return of masseter function. I have tried the masseter injections myself and space the treatments around 4 months apart, but use smaller doses to maintain the effect. I normally know the effects are wearing down when I start to clench my teeth more heavily at night when asleep. Once you stop using Botox, the masseter muscles will return to their original baseline when the effects of Botox wears off completely.

Thank you for your question and photo post.It looks like you have been doing your homework. Botox is a great treatment to improve facial symmetry caused by masster hypertrophy. A consultation would be needed to ensure that it is indeed the masseter muscle. The treatment can be performed at the consultation. Typically 25 units is all that is needed.I hope this helps.- Dr. Bryson Richards (Las Vegas Plastic Surgeon)

Masseteric Botox Cosmetic® injections can soften a strong masseter muscle and fix jawline asymmetries. In fact, elongating the face and softening a "square" jawline by injecting Botox Cosmetic® into the masseter muscles is currently the most popular use for Botox Cosmetic® in Asia. Since masseter Botox injections are an advanced technique please consult a board certified aesthetic dermatologist for a cosultation.

As we age, the natural boney asymmetry starts to show itself more because we lose the fat volume of our face. If you look closely, the right side of your face is overall a little larger and that is actually the skull that is asymmetric. It's like this for everyone, although some are more asymmetric than others. Find a full face shot of Angelina Jolie for a great example of significant asymmetry. An experienced injector can help balance both sides, but remember, we are all different side to side and seldom are we seen with such a critical eye by others as we see ourselves. 

Botox can be very useful to correct facial asymmetry.   The best approach is to try small doses of Botox and then see the patient in 3 to 4 weeks and add a little Botox if necessary and it often is necessary,.   This step wise correction can lead to really nice symmetry and saves the patient a lot of money from using big doses.  Facial symmetry can be corrected in Bell's Palsy patients, in stroke patients, and in trauma patients.  This application takes multiple sessions but it is well worth the great improvement and pleasing contours.   My Best,  Dr C
