Dr. Charles Mok explains how Botox dose affects how long results last. The original 20-unit dose lasted about 3 months; 30 units extends that to 3.5 to 4 months. Doubling the dose only increases duration by about 50 percent, not double.

So what happens if you use more units? There's a dose duration curve. Let's say the Glabella, which is between the eyes. The first approved dose was 20 units by Botox in 2003. That time it was the newest thing. 20 units, you'll have about two thirds of people getting a decent response. They'll last about three months. However, if you do 30 units, about 95% of people for about three and a half months, if you zoom in, last just a little bit longer, but we'll see in about three and a half to four months. Now, if you double the dose of neurotoxin, you go from 30 to 60. Doesn't last twice as long. It'll last about 50% longer. More so with xeomin than with Botox. Dysport. They're not quite as linear. If I have somebody that's traveling away, they're going to Europe for six months. I'm putting 100 units ago. Bella. There's no risk to it spreading into other areas. From that amount of units, it'll just last longer.
