How much Botox is safe in one appointment? I'm having forehead, temple, masseter and fillers for the nose.

Thank you for your question! I believe this is up to your physician to decide upon consultation. They can best decide how much filler is best for you. 

Yes, you can do multiple areas at once. The amount of Botox needed will vary. Keep in mind, it will take 1-2 weeks for final results with Botox and fillers. See an expert. Best, Dr. Emer
