60 units of Dysport in jaw. Is this enough to see any results?

I would say 30 units for each masseter muscle would be the low end of the range I would use, but I have used that amount in some people with an adequate effect.  I would wait a couple of weeks after the treatment and more could always be added if needed.  

Hi,Thank you for your question.30U of dysport per side is a conservative treatment but there's no problem with starting low- you may just need a touch up at 2 weeks.I typically start with 40-50U per side and reassess the masseters at 2 weeks. Since the masseters are a bulky muscle, it can take more than one treatment and a couple of months to see the full results as the muscle atrophies.Hope this helps!
