In this segment Dr. Charles Mok explains how neurotoxin products differ in their dose‑duration curves. He notes that Botox shows a weak dose‑duration relationship, whereas Xeomin exhibits a stronger curve, meaning more units tend to extend effect duration. On average, using the same unit count as Botox, Xeomin provides roughly two to three extra weeks of benefit, allowing clinicians to extend treatment intervals from the typical three‑month Botox schedule to about four months for Xeomin. This can reduce the number of annual treatments for patients. Dr. Mok also shares his practical preference regarding Dysport, citing confusion over unit conversion and its less predictable spread, which makes it suitable for some areas (e.g., forehead) but less reliable elsewhere.

Now there's something called a duration curve, dose duration curve. And the more units used, does it last longer? Well, that is the case with some of them, but not all of them. Botox doesn't have a very strong dose duration curve. Xeomin does. So I like that as well. Also, Xeomin, on average, if you use the same number units as Botox, you get about two weeks more out of it, maybe even three weeks more out of it. So it gives the advantage of lasting a little longer. In fact, historically, we schedule patients for Botox every three months. And we started putting Xeomin in the GLA and Orbicularis remove people out to four months. So it actually saves them a treatment a year, basically, or treatment every two years. I have preferences based on some practicalities. Again, dysport, I think that's a great neurotoxin. We don't use it because there is confusion with the units and it's uncontrollable in the spread, which might make it great for the forehead, maybe not so great for other areas.
