Dysport in the Same Quantity As Botox for the Same Result?

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 equivalent. This also affects pricing per unit by injectors who price these products by the unit. While there is no exact conversion rate, most injectors consider 2.5 - 3 units of Dysport to be equivalent to 1 unit of Botox.
This mean that if a patient requires 50 units of Botox to achieve the desired result, they are likely to need approximately 150 units of Dysport to achieve similar results.
All the best,

No, the number of units required for the same effect are different for Botox and Dysport. Dysport will require more units; generally, we find that around a 2.5:1 ratio of Dysport to Botox will provide equivalent results. Your dermatologist should be able to let you know how many units of Dysport vs Botox you would need to accomplish your desired results. 

I use both Botox and Dysport interchangeably in my practice. I often encouraged both my patients to use both Botox and Dysport so they feel confident that both treatments work just as effectively. I do notice that Dysport may onset a little faster with the dosing that I use. I also charge the same per region for either product. The makers of Botox and Dysport often have promotions or rebates, and I do which works out best for my patients at that particular visit.As far as dosing goes, Dysport does require more units than Botox. As far as effective pricing per area, it is the same in my practice .

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. Best, Dr. Karamanoukian

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.
