I had xeomin treatment for crows feet, 3 units on a side of each eye.. Total 6 units. I don't like result!

I would recommend following up with your injector. It would also help if you posted some pictures of what you are referring to.

I suggest that you see your injector 2 weeks after injection and if results are not optimal then a top up can be done to achieve desired results.  3 Units on each side is a low dose with my dosing range for crows feet with Xeomin ranging from 12-20 Units depending on severity of lines.
