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.

Botox vs. Dysport units

There is a 3:1 ratio in terms of efficacy between the two types of neurotoxins. 300 units of Dysport will equate to 100 units of Botox.

Dysport Units vs Botox Units

The number of units required for Dysport is different than the number of units required for Botox. The conversion is usually 2.5-3 Dysport units to 1 Botox unit. The usual amount recommended for Botox at the glabella is 20 units and with Dysport it is 50 units. The cost is very similar despite the unit conversion.

Dysport and Botox Effective for Wrinkles in Equivalent Concentrations

Botox and Dysport offer similar results for wrinkle reduction. Botox is dispensed in a 100 unit vial; Dysport is dispensed in a 300 unit vial. Their equivalency (strength comparison) is 1 unit Botox: 3 units Dysport, approximately.

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


Although Botox and Dysport are both highly effective products, they are not equivalent. The correct ratio of Dysport units to Botox units is somewhere between 2.5:1 and 3:1; it varies depending on the thickness of the facial muscles. Dysport's onset of action is faster; in some patients, it last longer than Botox, whereas in other patients, it doesn't last as long.
Hope this helps. Best of luck.
