First time Botox. Was 30 units between eyes and 20 units in frontalis muscles too much? Inner eyebrow drop, looking angry.

Hey there  - thanks for the question. 
I'd probably clarify with your injector about which brand they used. 20 units for the forehead is a huge dose if they used botox - but if the brand was dysport (a different type of botulinum toxin) it would have been a modest dose - and 'spocking' could be corrected with a little bit more in either side.

It is hard say without a photo or an exam what you would or would not need.  I would return to your injecting physician to correct any Spocking that is occurring. Also discuss what you didn't like so you have a plan for the next treatment. Good luck.
