I was injected botox incorrectly when it will gradually wear off?

Botox usually wears off between 6 - 9 months and in some cases it can also happen as early as 3-4 months. 

Thank you very much for your
question. I’m sorry to hear that you did not have a good experience with your
recent Botox injections. The results from Botox will wear off on their own,
however this will take from two to three months. There is nothing that can be
done to ‘remove the Botox’. Remember, only choose a Botox injector with
extensive experience, working under the guidance of a board certified plastic
surgeon, as this will reduce the chance for complications.

I'm sorry to hear of your issues with your Botox treatment.  Botox will gradually wear off over three months.  Unfortunately there is no way to reverse the effects of Botox.
