Usually about 10 units per side for crow's feet

Leonard Lu, MD answers: How many units to Botox crow's feet?

I have had Botox for a few years and love it. I have changed my location. I have a new person doing Botox, my problem is I have always maintained 22-24 units that has been perfect and on one occasion 28 units. Which was great as well. My problem is this, my new person that is doing Botox has guessed 39 units I was shocked, I told her no.

Dosage for Botox varies on the individual and the result that one wants to achieve. A knowledge of the anatomy definitely makes a difference in how much is used. What I mean by this is that if you know the exact muscles you want to target with the Botox, often less units are necessary. I usually use about 10-12 units per crow's feet, but there definitely is some variability from individual to individual.

I agree with many of the other physician's comments. 6-10 units per side is commonly used.

If you require more than that you may be building a tolerance and your therapeutic dose will need to be adjusted on a personal basis.

As you can see from the responses - there are many different units that work for the crow's feet area. Each patient is different but typically you need about 12 or so units per side as you had been getting and you were happy with it. I would discuss the number of units you needed before with your physician and try that amount again. If it is for some reason not effective you can always go back for a touch up and then begin to get the new, higher amount from then on. Remeber, the more units used the higher the fee. So make sure you are using a board certified physician who is reputable and has good references. There is nothing wrong with sticking with what has worked for you.
