3 days after Botox injection to the masseter to slim the jaw, I don't see any effect, should I go back to the doctor?

Thank you very much for your
question and congratulations on your recent Botox treatment. It will take from
one to two weeks for the results from your Botox to become apparent. At three
days post-treatment, it is too early to note any results. Over the next several
days, you should start to see some changes in your jawline. If you have any
further questions, I recommend contacting your Botox provider.

You have received an adequate dose of Botox.
The effect of Botox (muscle paralysis) starts at four days.
Botox's full effect (paralysis) occurs at two weeks.
It takes six weeks to visually observe shrinkage (atrophy) of the masseter muscles after Botox injection.
Be patient. 

It can take as long as a week or two to see the effects from a Botox treatment, so it is not unusual that you see no effect on your masseter muscles 3 days after your injection.  You will first notice that the muscle does not clench as much and then over more time, you will see a slimming effect.  

Botox results can take 1-2 weeks and will last 3-4 months in new areas of treatment. It may take a series of treatments and a combination approach with radiofrequency to get improvement. See an expert. Best, Dr. Emer

Botox takes two full weeks to take effect.  If after that you don't see any effect return to your provider.

Thank you for your question. It typically take up 2 weeks to see results with Botox. However, Botox for the masseter can take 2-3 treatments before seeing full atrophy of the muscles and to see your desired results. Best of Luck!

Botox is an outstanding treatment for masseters. It softens the area thereby slimming the face. Typically, it takes 4-7 days to see the full effect of a treatment and in some patients, it may take up to two weeks. Give it a little more time. At the two weeks mark if you're still not satisfied, please visit your doctor. As always, you should trust your care to an expert in facial aesthetics such as a board-certified dermatologist to maximize results and minimize side effects.

After the masseter muscle injection it may be a week or two before you feel your jaw soften and see some slimming.

Thank you for your question. Botox injections may take up to two weeks for full effect. Masseters are large and strong muscles.  A series of Botox treatments may be necessary to achieve best results. I recommend following up with your injector in two weeks. All the best, 

Thank you for your question Keithlaw91. Botox is a purified protein used to address wrinkles associated with
facial expression. The pivotal studies demonstrated that the peak effects of Botox are seen two weeks after the treatment. Patience is important. Please consult with a doctor for specific recommendations. Good luck!
