How many units to Botox crow's feet?

I generally use less than 7.5 units per side for crow's feet ( a total of 15 units)and have the patient come back in two weeks for a followup visit just in case they need more. I would much rather under correct in this area than over correct because this is one area where you could get complications such as... more

The dosage of  Botox depends on the degree of wrinkling and the history of prior eyelid surgery. For an average person in their late forties I use a range of 30 -35 units whereas on a much younger patient I may use 18-25 units. Also, there is variabilitiy related to a patient's sensitivity to botox. Some... more

Each individual needs different amounts of units depending on their anatomy.  that being said if my patient said that 20-30 units was all that they have needed in the past and had great results that is what i would stay with.  I personally dont remember ever having a patient who needed 40 untis... more

As previously stated, the amount of Botox used in this area is dependant on the strength of the muscles. Patients with thicker, stronger lateral obicularis oculi muscles (often seen in men) will require more Botox to treat that patients with thinner, less strong muscles (older patients with thin skin and... more

This would depend on the lines and their formation. If a single line less units. Multiple lines more units. If the wrinkles extend quite a distance from the lateral canthus (outer part of the eye) more units. It is safer to inject the superior lies ( upper wrinkles) than lower ones. Usual for me, like the... more

Bev, I start with 8 units of Botox on each side - placing 1 to 2 units per injection.  I will then see the patient back in 2 weeks to determine if additional Botox is needed - this way I can incrementally determine the optimal botox dosage to give the desired results. Once the right number of Botox units... more

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... more

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... more

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.

You are getting a lot of Botox.  Consider that one vial contains 100 units, so you are getting nearly 40% of an entire vial.  At best, you are getting more than you need, and at worst, you may be at increased risk for temporary, unwanted muscle weakness/asymmetry.
