Can Botox stop working after regular use?

The simple answer is, “yes, but it is rare”. Perhaps
you need a higher dose of Botox, or you can try to Dysport or Xeomin. My exxperince is that optimum results are
often NOT achieved when anatomy is properly considered. It is important that
Botox be injected into the proper muscle group. In contrast to popular belief
your doctor (or a nurse that they directly supervise) should have the best
grasp on your specific condition, and use this knowledge for placement and
dosage accuracy. An optimal response can
be achieved using minimal dosages with proper placement in the appropriate
muscle groups. By understanding the facial anatomy, one can use Botox not just
for wrinkles, but also as a treatment to reshape and soften certain facial
features that can be associated with frowning, anger, or just simply aging. In
order to determine if you would benefit from retreatment with Botox, a proper
physical exam is necessary. 

Hello, Thank you for your question. Very rarely does Botox stop working for patients. Perhaps you could speak with your qualified injector for alternate option, such as Dysport. You should also discuss your concerns with your injector. Take care. 

While increasing the dose may be needed in some individuals, this is not typical of the average patient. Perhaps try switching to Dysport or Xeomin.
