Botox dosage VS Dysport dosage?

BOTOX - 25ū each jaw, 37.5ū for forehead&glabellar&crowfeet (can't remember specific unit on each area). DYSPORT - 100ū each jaw, 70ū forehead, 40ū glabellar, 50ū crowfeet. Based on the units mentioned above, which one is stronger if inject to a same person? Botox or Dysport? How's the calculation work? Hopefully to hope from you all soon. Thanks.

Botox vs Dysport

Botox comes in 50U and 100U bottles. Dysport comes in 300U bottles. Assuming the Botox and Dysport are diluted equally (with 3 ccs of sterile saline) and the mixture is fresh, there is 1U of Botox for every 3U of Dysport.

25U B = 75U D and you received more: 100U D to jaw
37.5 B = 81.5 D and you received less: 70U D to forehead, 40U glabellar, 50U crows feet 

Consult a Board Certified Plastic Surgeon

A recent study - Based on a triple blind study conducted by triple board certified, celebrity plastic surgeon Dr. Ramtin Kassir, a test of the efficacy and safety of popular injectables, brand named "Botox" and "Dysport;" it is now affirmed that Dysport delivers faster and longer lasting results than other comparative botulinum toxins.

I don't believe this study was a randomized, double blind, prospective study so take it for what its worth.

How many "Botox units" of Dysport are needed

The conversion I use is 2.5 units of Dysport to 1 unit of Botox. So multiply the Botox units by 2.5 to get a good starting point for Dysport dose that will be required for a similar effect.

I like to use 4 to 1 Dysport to Botox

I like to use a 4 Dysport Units  to 1 Botox unit.  Most of my patients who have used both feel that they get a little faster onset and longer duration with a dose higher than the 2.5 to 1 conversion.

Dysport Units Compared to Botox Units

There is no perfect answer to this question.  However, most people get a near equivalent result using 2.5 units of Dysport where they would have used 1 unit of Botox.  You are getting Dysport at 4 times the Botox units in your Jaw, so I would expect a stronger result with Dysport.
