I had Botox 2 weeks ago and have broken out in pimples all over my forehead?

I agree that it may have been the numbing cream that caused the break out, Its best to follow up with your medical provider to evaluate you

There is only one type of Botox. There are other neuromodulators - Botox, Dysport, and Xeomin all being options - is this what you mean? My suspicion is that you have some kind of outbreak due to the numbing cream put you on before the injections are done. "This answer has been solicited without seeing this patient and cannot
