Just had 50 units of botox on forehead. Is this too much? (Photo)

Thank you for your question.  On average most patients require 16-24 units of Botox and 50-60 units of Dysport for the forehead.  You  may have had Dysport.  If your happy with your first physician injector, and he gave you good results, then i would advise you to continue going to him/her.  Best wishes.   

50 units of Botox would be excessive to fully treat forehead rhytids (horizontal forehead lines), but it may be appropriate to treat both the glabella and forehead.  A typical dosage for the forehead is 20 units.  50 units would be more appropriate as a Dysport dosage.  

Thank you for your
question.A higher amount of units injected will not make your botox last any longer than normal. 3-4 months is an average of how long Botox will last. To be sure, see two
or more board-certified providers in your area for a complete evaluation to
make sure you are a good candidate and that it is safe for you to have
treatment.

I hope this helps.

I suspect that you had 50 units of Botox to the glabella and forehead.  I find that to be excessive given your photo and your age.  Increasing the amount of Botox that you receive does not increase the longevity of the Botox.  25 Units lasts as long as 50 units and the only improvement you will see is increase in effect of having more Botox for the same duration of time. 

The issue could be terminology.  Most injectors refer to the muscles above your eyebrows as forehead muscles but some injectors also refer to the muscles between your eyebrows as forehead muscles.  This area is a different set of muscles and is usually referred to as the glabellar area, the frown lines or the "elevens".  Perhaps the second doctor treated both of these areas for you.With Botox cosmetic, the forehead muscle in most women takes between 6-20 units, the glabellar area between 15-30 units, although both areas can take more in some women.The other possibility is the second doctor gave you Dysport.  50 units of Dysport is approximately equal to 20 units of Botox.  Dysport units tend to cost about 1/3 of what Botox units cost however.
