Why do some areas of the face seem to require more Botox?
This is a good question but it’s a little hard to answer without seeing you. Let’s take crows feet, for example. I have some women in their 30-40s who have very active muscles here and some women in their 50s who have very few lines so age alone is not the best predictor. As many of you know, I don’t think Botox should be sold in “units” although this practice is very common. But, I would say in our practice the most common number of units for an average sized female is usually 15-25 units for crows feet around both eyes (or 7.5-12.5 for each eye). There are women outside these parameters and men almost always need more.
The other thing to consider around the eye area is whether the problem is really more loss of volume? If volume is the problem, then the Botox won’t be effective until the volume is replaced. Dr. I
