Will tensing/wrinkling injected facial muscles soon after Botox or Dysport administration cause migration to unintended areas?

I do not believe that tensing or wrinkling the facial muscles treated with Botox or Dysport will cause migration of the product to unintended areas.  I also do not believe that tensing or wrinkling those muscles affects the results in any way.  

There is no research out there stating that if you tense your muscles following a botox injection that it will make it work more effectively. In addition, ,you don't have to worry about the product migrating. However, for 4 hours post injection i would avoid rubbing and touching the area tanning and saunas. 

Thank you for your question, and I am not aware that by forceably or actively using these muscles will there be any effect one way or the other. Using these recently injected muscles will not cause it to migrate or make it act faster. Botox will typically begin to "kick in" after 4-7 days, but some may see results earlier. The full effect is usually seen after 7-10 days so two weeks after your injections is a great time for a follow-up with your injector if you are not getting the results you desire. Additional injections may be given at 2 weeks if more correction is desired/needed. Botox typically lasts 3 months, and after that it begins to slowly wear off. I tell my patients not to rub the treatment areas or lie down for 4-6 hours after injections to be safe.
