Can you get the Pfizer vaccine 4 days after Botox in forehead and does it reduce the efficacy of the 2nd dose?

It is fine to have the COVID vaccine 4 days after your Botox treatment. It will not reduce the efficacy of either dose.

Hello and thank you for your question. We always recommend a face-to-face consultation for advice however from what you have provided here there is no reports of botox and the cover vaccine being problematic so there should be no issue.
I hope that helps, please always a seek a qualified and experienced practitioner for any cosmetic treatment, best wishes
