Is 10 Units of Botox Per Side Too Much for Crows Feet?

The average number of units for crows feet is 25-30 units. If 5 units work for you then this is all you need. The higher dose will usually last longer, but you should use the minimal amount necessary to get the look you want.

For crow's feet, I use anywhere from 6 to 16 units per side, with an average dose of 9-12 units per side.  Six units per side is reserved for people that barely have any crow's feet, even when smiling broadly.  Sixteen units per side is for people that have crows feet that go up to the temples and down the cheeks.  Nine to twelve units per side works well for most people, who are in between.

Remember, also, that higher dosages typically last longer than lower dosages.

All good feedback from panel members.  10 units per eye area is a very standard dose for most.  Although you are still quite young, the "recipe" is determined by muscle action at the time of the treatment regardless of age.  Much may change in the two years since you had your first dose at 5 units each side.  If you tend to animate mostly around the eyes, then 10 units is not unreasonable. 

Your final decision on your treatment plan should be determined by the end result and duration.
