Is Botox a permanent solution for masseter hypertrophy?

Thank you for your question.Botox is not a permanent solution for masseter hypertrophy. You will require a series of treatments. Please schedule a consultation with a board certified plastic surgeon. Best, 

While a single treatment of Botox for masseter reduction will not permanently reduce the size of the masseter, muscle, serial treatments will cause a long lasting decrease in the size of the muscle.  Just like any other muscle in your body, while the masseter muscle is unable to contract and "work out" while treated, it will shrink.  

Hi tahha, thank you for your question! Botox is a great non-invasive treatment for masseter hypertrophy! However, it is not a permanent solution. Botox will temporarily cause the muscle to weaken, diminishing it's ability to fully contract. When the muscle cannot fully contract it will slowly atrophy (decrease in size). While the Botox will kick in fully by 2 weeks the slimming effects typically takes up to 30 days to see results as the muscle requires time to atrophy. We recommend treatments every 4-6 months.
I've created a video that reviews treating the masseters with Botox. I hope you find this helpful in your research.

Botox is not a permanent solution for treating the masseter, however it is still very effective. Patients will need regular Botox treatment sessions, but over time they may need them less frequently. 

Botox has a temporary effect to weaken the muscle with each treatment.  However, over time, if Botox is injected every 3-4 months I have seen significant atrophy of the masseter muscle and a decreased need for injections of Botox with some patients only coming in once per year to maintain the result.

Thank you for your question. Botox results are never permanent regardless of the injection site. You will need to get treatments every 3 to 5 months as the results will wear off after this. If you use the product over a period of time it is possible to cause some muscle atrophy in the area which will prolong results between your sessions. I would recommend consulting with a plastic surgeon in your area to discuss your options. Best Wishes,Pablo Prichard

Botox is not a permanent solution to enlarged masseter muscles. However, most people not improvement for 6-12 months and require smaller amounts of Botox over time with consistent treatment. In skilled hands, this is a safe and very effective treatment options. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Botox is currently not considered a permanent solution for masseter hypertrophy, but does seem to last very long in some people to improve their masseter hypertrophy.  While the other cosmetic Botox treatments for wrinkles may last only 3-4 months, many of my patients claim their masseters stay improved for a year or more.  This may be because the muscle is atrophied from lack of use after Botox and unless the patient chews or grinds alot it will return to original strength only very slowly.

There is no guaranteed permanent solution for this, although you may find once you reduce the size of one side, unless you are always chewing on that side only, you may retain some of the improvement in symmetry.Patients are generally very happy with this treatment, and it is generally safe and effective. The required dose varies from patient to patient, but larger doses do last longer.

Botox results are never permanent, regardless of the area injected. With continued treatment some muscles may atrophy more and therefore seem more affected for longer, but it's never permanent. Over time, the treated area will return to its pre-treatment look. "This answer has been solicited without seeing this patient and
