Difference between Dysport and Botox
Abdolutely not. You should require about 2.5 times the dose. For example 10 units of Botox is roughly equivalent to 25 units of Dysport. 20 Units of Botox compares with 50 units of Dysport. There may be some differences in length of time to onset, longevity of results, and diffusion patterns once injected.
Dysport Units and Botox Units Are Not the Same
Dysport and Botox units do not equally correspond to each other. In fact, there is no specific magic ratio of comparing the two. They are both excellent botulinium toxin neuromuscular regulators, but their units have been established in separate labs using different experiemental animals, etc.
The ratios that are often quoted are 1 unit of Botox Cosmetic is "equivalent" to 2.5 to 3 units of Dysport. These are estimates for physicians to be able to approximate how much Dysport to use in certain areas. It has been shown that the ratio can be variable between patients as well as in different areas on the same patient's face.
Choose your injecting physician carefully.

How many units of Dysport for a unit of Botox?
We treat dysport as a different neuromodulator than Botox, but if you want to compare units the ratio is somewhere between 2.5:1 to 3:1. In other words, if you're used to getting 20 units of Botox for your frown lines and 20 for your crows feet, you'll need about 100-120 units of Dysport to achieve the same results. Don't get too caught up in units and price/unit. The point is to achieve the results you want with the least amount of injections.
On the horizon are other alternatives to Botox and Dysport- these are Xeomyn, Puretox, and Canitox. Xeomyn has already been FDA approved in the US.

A unit is not a unit when it comes to Botox and Dysport
Dysport is new in the US, Botox is not. Because it is new it is probably a wise idea to have someone who is very experienced with Botox to give you the best result. You don't want to be a guinea pig to someone who has little Botox experince and next to no Dysport experience. As a Botox provider I am in the top 1% in the country so our office had no difficulty making that transition to using Dysport. Be careful and Good Luck!
Dysport and Botox dosing are not equivalent
Units of Dysport and Botox are not the same
No. Dysport has a different treatment regimen. Most patients should expect MORE than a two-fold increase in Dysport units to match the Botox effectiveness. Even a three fold difference might be used. Your physician will determine what is best for your skin. This may occur over several treatment sessions as your results will help the doctor titrate the best dose for you.
