Glabeller botox - what sort of provider?

I'm looking at getting glabellar botox for the off-label use of potentially helping depression/anxiety.

There are so many options for where to go for this sort of thing - a dermatologist, a plastic surgeon, a "med spa."

I've never had anything like this done before and obviously have a vested interest in it turning out well LOL. Is one of those options preferable to the others/has better outcomes? Or maybe it's all a crap shoot and I should be looking at reviews instead?

Any guidance greatly appreciated. 😅
