Eyebrow arch after Botox for crows feet. Is this unusual?

Depending on the injection technique and placement, the shape of the brow can certainly be changed with botox application.  I frequently will "sculpt" a more aesthetically favorable brow using botox.  Occasionally botox can be applied and the brow shape will temporarily change in a less than favorable way.  This is temporary, as the botox effect lasts for about 3 months.  Following up with your doctor is important so that they can correct the problem if possible or that they can adjust their treatments in the future.

The wonderful thing about Botox is, that if you understand the muscles of the face, you can use Botox less or more in different areas to get the desired look you want.  If there is a bit too much relaxation in the muscles that raise the outer part of the eyebrow, you can "fix" it by relaxing the adjacent area.For some practitioners, Botox is a process that is profitable.For others, it's an art form.
