What should I expect after Botox masseter for one month? Face slimmer or Botox starts to wear off?

Question

I got the first time Botox on June 25, 30 units each side. After 2 weeks, I felt sore while I was chewing food and my muscle doesn't clench up anymore. However, it is almost 5 weeks, and I don't see any change. People around me don't see any change either. On the other hand, my jaws don't sore anymore. Also, I start to feel my muscles again (although they aren't strong). Now, I am wondering if I should expect to see my face slimmer at this point, or if my Botox starts to wear off. Thank you,

IF you are unhappy with the cosmetic outcome you can add more to the jawline, but that is if you were a good candidate to begin with  the results are subtle and should be appreciated by overlapping the before and after photos.

Jonathan Kulbersh, MD · Answer

Botox is commonly injected into the muscle on the jawline to improve the pain and discomfort from grinding and to slim the jawline. Botox relax muscles over a one-week time period.  After this week, patients will typically experience improvement of their pain and soreness and feel the relaxation of the masseter muscle.  Shrinking of the jawline is secondary to atrophy of the masseter muscle. This process will occur over a 3 to 4 months time. I would wait until that time to judge the results. Before-and-after pictures can be helpful and objectively judging this limit of your jawline secondary to Botox in your masseters.I hope this helps

Botox for masseter is extremely effective at slimming the jawline when good relaxation of the muscle is achieved.  Especially since you have noticed your masseters have gotten softer, the muscle will show a visible difference in size over the 3-4 months that the Botox is active.  Most patients will see a slimming effect in 4-6 weeks after treatment, but rest assured that the muscle will continue to slim over the next 3-4 months.

Martin Jugenburg, MD · Answer

Typically it can take 4-6 weeks in some patients to notice a slimming effect provided you were a good candidate for this treatment.  usually another treatment of the same amount of units 3 months later will give you a more noticeable result.

Michele S. Green, MD · Answer

It sounds as if you had the correct response and dosage with Botox.  Sometimes, it takes more than one treatment to see the muscle shrink and can occur over a period of months.  I would repeat the procedure in a few months.  Best, Dr. Green
