My Botox keeps wearing off after 5 weeks. What could cause this?

Thank you for your question and concern.  I train a lot of injectors in the proper technique for Botox injections.  One of the most common reasons I find that injectors have variations in the results is that they are doing the same injection for every individual. I.e., they don't use the assessment of the individual to develop a customized plan.  If they do, it is usually by varying the dose rather than varying the location of injection by understanding the differences in surface anatomy of the individual patients.  There are patients who truly have shorter durations with Botox and may want to consider the different neuromodulators available to see if there is a difference.  However, more often, the same technique that is used on another patient  may not be working for you.  I would recommend that you go an experienced board certified plastic surgeon or dermatologist who does a high volume of injectables to discuss your experience in more detail.

BoTox, and all forms of Botulinum Toxin A, work by blocking the reuptake of acetylcholine at the neuromuscular junction. By doing so, it inhibits transmission of signals from one neuron to the next at whichever junction it is working on (e.g., neuro junction, sweat gland junction, etc.) The duration of BoTox is typically 3-4 months on average. It can take up to 7 days for it to take effect. You out may simply need more BoTox if you have very active muscles.  Follow how much is being injected so that you can determine a good medium for you. Thank you for the question! Hope this helps!

Hi Bella. You don't mention which area you got treated, but usually 40 units is enough to treat most areas of the face and have it last for 3-4 months. Usually the most common reason that Botox does not last long is that there is not enough of it given. If you are paying a low price for your Botox then it may be over diluted and you may not be getting the actual number of units that you think you are. Hope this helps!

Thank you for your question! First of all, the dosage (whether it has been properly diluted or not), secondly the duration and the consistency of use and last but not least, the experience of the provider who does the Botox injections. There are many reasons to determine why it is not lasting as long for you. The most likely reason is simply that some people typically need more and some people need less; you might just be needing a little more than the average person due to strong muscles. You should contact your injector if you are not satisfied with the results or consult an experienced provider to help you out. Best of luck! 

The first thing that comes to mind is injection technique
and injector experience. Botox is dependent on proper injection technique and
experience. Board-certified dermatologists, plastic surgeons and their teams
should be well versed in all the proper injection techniques that we are
currently using, and we would encourage you to find out about the experience
level of the person injecting the Botox. On occasion, you will need more Botox
in certain areas, but this is not the usual case. And now with different toxins
out there, such as Dysport and Xeomin, perhaps one of the others may be more
appropriate for you moving forward.
