Can I get local anesthesia in my forehead so that I can have Microblading and Botox at the same time?

Yes - you can do this and we often do microneedling at the same setting as botox (we just do the microneedling first).  I typically use a topical anesthetic which works well though an injectable would be no problem.

thank for you questions. You should never have Botox and other Esthetic procedures in same time ,specially in same area of your face. It's risky to have more complications. I will suggest to have separate session
Good luck

Yes, it shouldn't be a problem to offer local anesthesia for the two.  Botox in general is fairly painless.  Sometimes I place topical.
