Would corrugator resection get rid of my frown line between my brows? (Photo)

Dear Brave,
If you've had that wrinkle since your 20's and you've adequately tried chemodenervation (Botox), then corrugator resection is probably not going to do much either. The operative word here is "adequately." A long standing, deep crease like yours would take many Botox treatments performed regularly over a long period of time, e.g. a year or more, to see a difference. The question then becomes did you, or your practitioner, see a decrease in corrugator muscle activity after Botox and you just didn't continue it on a regular basis for a long enough period of time?
