When I visited for the first time to get chin botox, they recommended 150 units since I have a lot of chin muscles, so I got the treatment.
(If there is too much, will there be any side effects? They say there are concerns)
 
I looked it up and it seems that 150 units of chin Botox is too much..?
Is 150 units okay for the first chin Botox treatment? Are there any side effects?

My jaw is well developed, and I exercise a lot on a regular basis, so I have quite a lot of jaw muscles.
