Does anyone have any experience getting mesotherapy?

Little evidence. I'm not a big fan of mesotherapy, and am not aware of any significant well done study, published in a peer-reviewed journal, that documents its safety and effectiveness. I don't recommend it to my patients. There are reports of complications.
