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

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

Botox injections are as much a science as an art.  As a plastic surgeon, I begin my evaluation by noting the amount of skin resiliency in the lateral canthus, the condition of the skin, the severity of dynamic wrinkling, and the extent of static wrinkling.  These parameters should all be... more

For younger patients in their 30's, 8 units usually suffices per side; for patients in their 50's it might be 16 units per side, if orbicularis fibers other than the usual lateral fibers are treated. Too much Botox can cause relaxation of undesired muscles, for example the lip lifting muscles, so experience... 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

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

For crow's feet, generally I instill 10 units per side. Unfortunately every patient is different and sometimes increasing dosages are needed to get the desired results. My suggestion would be to start low and go high. In other words, have your physician start with the number of units you received previously... more

Bev, The number of units varies between people because of different muscle structure. Additionally, the number of units may also differ between injectors based on the "freshness" of their Botox. The longer Botox sits around, the more it becomes denatured and is less effective. I, for instance, always mix up... more

I generally use between 7.5 and 12.5 units of Botox per side for crow's feet, depending on the patient. However, there are some patients who have smile lines around the eyes that can add to the attractiveness of a patient. Some smile lines add warmth and pleasant character to the face. Lines and wrinkles... 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
