Hi Karen. We use a 3:1 conversion from Dysport to Botox. That would be 120 units. We do this because we can offer 3 units of Dysport at the same price as 1 unit of Botox and feel that the duration at a 3:1 conversion is better for Dysport than for Botox. We have tested this over and over again for many years and have transitioned our whole practice to Dysport. Our patients love the results.To see our complete analysis of the pros and cons of Dysport vs. Botox, click the link below.
2.5 is probably a bit low and 3.0 is probably too high. However this is the neighborhood. Make sure the doctor is taking before and after photographs so you can actually study your treatment effect.
