My face is too thin after botox to masseter muscles. Is it permanent?

From a safety standpoint, one of the best features of Botox is that its effects are always temporary.  It works by relaxing muscles, and in your case the masseter muscle.  In 3-4 months your masseter muscles will begin to regain bulk as they begin to "work out" once again after the Botox has worn off.  

No. These results are not permanent. Botox masseter treatments require maintenance for long term improvement. Wait this out and give things 3-6 months to improve. Filler is always an option if the end result is still too thin for you. However, you are likely to see the Botox effect wear off completely. Best.

It is unlikely that the result will be permanent. When the Botox wears off in 4 to 5 months, the muscle may be slightly less full but will return to normal fullness over time as the muscle exercises through your normal facial movements. Volume replacement with products such as Sculptra can be used to restore lost facial volume.I hope this was helpful.

This is not permanent and will last 3-4 months and then return to normal . I suggest speaking to your physician if you are concerned.  Best, Dr. Emer.

 Thank you for your question.   Sorry to hear that you had a bad experience.  You will find that the results gradually wears off over the next six months.  

Hello, Thank you for your question. I'm sorry to hear about your experience. These results shouldn't be permanent. Botox results typically will last up to 6 months.I'd recommend booking a follow-up appointment with your skilled and qualified injector to share your concerns and to determine your best options. Take care. 

I'm sorry to hear you've had a bad experience treating your masseter muscles with Botox. Treating the masseter muscles with Botox weakens them. As with any muscle, when it is not being used it atrophies (decreases in size). Botox treatments to this area work to alleviate symptoms of TMJ but are also done cosmetically to slim the face. The effects of Botox to this area typically last 3-6 months, afterwards your muscle will strengthen and with time increase in size again! I recommend speaking with your injector to adjust your dose for any future treatments. 
I've created a video that reviews treating the masseter muscles with Botox/Dysport. I hope this helps in your research! 

Great question.  Botox effects are only temporary in the muscles; therefore, your facial volume should return to normal in 4-6 months after your last injection of Botox.
