3 wks after botox (45 units for my glabellar) , I'm still able to scowl & vertical lines appear on my forehead: Is this normal?

Thank you for your question.  One has to make sure of the anatomical regions treated.  The frown lines between the eyebrows is the glabellar region.  Anything above and on the sides is considered forehead.First and foremost, you should go back to your injector for an assessment.  In my 2 Visage Clinics, a normal dose for the glabella alone, for a woman, is 25-30 units, whereas for males, it is more 40-60 units.  Treatment takes effect within 3-5 days for most people.45 units for both glabellar AND forehead together, for a female, would be a normal dose.There are other neuro-modulator on the market and some require a higher number of units for an equivalent effect; we have Botox, Dysport and Xeomin.The injector is the one reconstituting the neuromodulator (it comes as a powder).  Make sure you see a qualified injector.  And remember, there is an art in all the injections available in Canada; neuromodulators, juvederm, restylane, Selphyl, Voluma and Volbella, Radiesse, Sculptra, etc.I hope this helped!Dr. Marc DuPere, board-certified plastic surgeon, VISAGE Clinics, Toronto and Richmond Hill, voted TOP plastic surgery Clinic in Toronto for 2013 by Consumers Choice.   416.929.9800

45 units a strong dose.  Unless you are a man with very strong frown, you should notice a difference.  Also 45 units is something that in our clinic is used to treat the entire forehead, not just the glabellar area.It's difficult to say why it didn't work for you.  Was it a "Dr" that did your treatment?  Was it really BOTOX and not some watered down solution?

Injecting 45 units of Botox to the glabella area is a very high dosage, your provider may have treated other areas with this amount, its best you schedule a follow-up
