Should botox be injected slowly or quickly?

Thank you for the question. The speed of needle insertion and injection of Botox will not effect the outcome. The most important factors are the skill and experience of the injector and the number of units being used. Make sure to go to an expert injector. Good luck. 

I appreciate your question.There is no difference on speed of injections.  More important is skill of the injector.  Slower injections usually means less bruising.  The best way to assess and give true advice would be an in-person exam.Please see a board-certified plastic surgeon that specializes in aesthetic and restorative plastic surgery.best of luck!Dr Schwartz
