How to Determine the Number of Botox Units I'm Getting?

This is a great question as every person who in injects Botox has a different "dilution" rate. Usually, 3-4cc is used to dilute each vial. Ask your injector how many cc's were used to dilute the vial. As each vial has 100 units, divide the number of cc's into 100 to determine how many units are in each cc. Each area of the face is injected with a different amount, so keep track of the total amount injected to calculate how many units you received.

It really is as simple as asking, as Dr. Neigel said, at least it used to be. Your injector will determine the right dose, and patients quickly learned to compare prices in terms of units a few years ago after Botox Cosmetic was approved. Now we have Dysport, another botulinum product, which has different units. In other words, 20 units of Botox equates to somewhere between 50 and 60 units of Dysport, though the cost to treat the same area is less with Dysport. So now we have to start thinking in terms of cost per area instead of cost per unit again.
