Botox (or Dysport) would be correcting the only FDA approved indication in your case. Many of our patients (our being myself and the contributors to this site...I do not allow our aesthetician to inject) tell us that their friends think they are in a good mood or have returned from vacation.
I would recommend that you try Botox injections once, and then decide whether it is worth maintaining.
Most of us have also noted that after three or four times, you can space your Botox sessions further apart. Some of us also are seeing longer results with Dysport (lasting 4-5 months) so you might look into that alternative.
