I had Botox and the nurse assistant rubbed my forehead a little too hard. What do you think?

Dear Karley416,
Thank you for your question. I feel it is unlikely that rubbing on the injection site will impact the result of your treatment. 
It usually takes 2 weeks to see the full and final results.
Hope this helps! 
Best wishes,
Mr Kambiz Golchin

It is highly unlikely that rubbing the skin will cause any adverse effect.  The belief that touching injection sites after Botox alters the effect of the medication is not entirely evidence-based.
