Yep, sounds like a form of lipotherapy. Not sure if they all use the same or similar ingredients in their injects. I would speculate that most do.
It's meant to work well. I think 3-5 treatments and you are usually good to go. But I image that as always, it needs to be coupled with a clean diet and strict exercise or the fats that are being broken down will redeposit instead of being completely reabsorbed.
I think it would be best targeted at stubborn deposits, especially in the face.
