How Long Does Botox in the Masseter Muscle/jawline Really Last?
I only had 15 units per side 4 wks ago & it "worked" far too well! My doc says it'll wear off in 3-6 months, many Realself docs have stated 4-6, but I've heard reports that botox for jaw reshaping lasts way longer than in the forehead, i.e. 9-12 months! Some even say it's permanent (!!!) Going by averages, how long will it be before jaw botox actually begins to expire, and from there, when can one expect to be back to their pre-botoxed state - if ever!? :S

Botox in the masseter area
How long botox treatments "last" in the masseter depends on a number of factors. One factor is if you are using a guard in your mouth to prevent grinding or clenching. The guards prevent the muscles from working very hard, so the muscles do not regain their former strength. I personally have had 50 units in each masseter for clenching, and wear a guard, and the muscle is reduced and soft over 9 months later.
If you are not using a guard, and did the Botox more...

Because you're using the Botox in a larger muscle (the Masseter), which continues to contract everytime you chew or open/close the mouth...the effects of the Botox may not last as long as when it's injected into the forehead where you can go without using the muscles. I like to do a full dose booster Botox treatment 1 month after the initial Botox treatment as a way to further weaken the targeted muscle(s).
For the Masseter, I typically use an increased Botox...

Botox Effect on Masseter Muscle Depends on Dose Given
As stated above, the longevity of the effect of Masseter muscle weakness after Botox injections, depends on a number of factors, the most important of which is the dose administered. Typically, for lower face shaping, we use up to 30 units per side, which is twice what you received. The effect generally lasts for 9-12 months. In your case, I would expect return of masseter strength and thickness within 6 months. If you are interested in reversing the effect of Botox...

Duration of Botox in the Jaw Muscle
Fortunately, you had a fairly low dose of Botox so it is likely to wear off in 3 to 6 months. There are many factors that can affect Botox uptake including hypertrophic muscles, muscle size, amount of nerve innervation, nerve stimulation, muscle activity and metabolism. Additionally it is interesting to note that in marathon runners and individuals that exercise more than 4 days a week, the duration of effect is slightly but noticeably less. Therefore it would be advisable for you to try to...

Yes, yes, yes, it will wear off.
Generally even with this small dose, it will take 4-6 months for the massetter muscle volume to return to normal. In terms of bit strength, this will begin to return to normal after a few months. Hang in there.

Botox and masseter muscle function and duration of effect
The duration of effect of botox is related to the dose used, the size of the muscle, and the number of neuromuscular receptors in the muscle. A dose of 15 units is relatively small and the masseter muscle is a large and strong muscle. Things should start to improve in 3 to 6 months. To help speed the process you can do some chewing execises with gum. This will help build up the strength and size of the muscle and reverse the problems...
