Matching Dysport concentration with Botox?

Matching concentrations is not needed to get good results. Each patient needs to be treated on an individual basis and their goals. I suggest you have a formal consultation with an experienced injector. Best wishes, Dr. ALDO 

Dysport and botox units cannot be interchanged. In studies is roughly 2-3:1 dysport:botox.  What matters is your doctor's injection technique. I like both toxins.  Best, Dr. Emer.

Both products come dry and are put into solution by the doctor.  Typically I dilute my Botox with either 2 or 3 ml of injectable saline.  That makes a solution that is either 50 units per ml or 33 units per ml of Botox.  The "equivalent" Dyport dilution would be 2 or 3 ml of injectable saline in one vial of Dysport.  In which case the finale concentration of Dysport would be either 150 units per ml or 100 units per ml of Dysport.  The clinical effect is that I am using a Dysport solution that has 3 times the number of units as I would use for Botox.  Despite all the whisper campaigns coming from these companies, clinically speaking the effects of Botox, Dysport, and Xeomin are all the same.  The onset and duration are clinically equivalent-end of story.  By the way, do not dream of doing your own treatment.  If you do, you will have a fool for a patient.
