Are there any long-term nerve damage caused by fat-dissolving injections that did not resolve?

Surgical choices are not an option for me so fat dissolving injections seems like a good choice, however I am reading more about it and it seems like nerve damage can in fact happen (although I read they all have resolved). I have been told I am a good candidate but am worried about nerve damage. I don’t care about the temporary side effects, just permanent ones. Is this a safe product?

Fat dissolving injections are injected into a “safe zone” under the chin, into a region known as the “preplatysmal fat”. This is to avoid the important structures that pass deep to the muscle in the neck, and especially to avoid injuring the nerve that controls the lips. Provided that this safe zone is identified, the injections are highly unlikely to damage the nerve. If the nerve is damaged, the resulting nerve damage (known as “neuropraxia” is temporary and has an average duration of 6-8 weeks). The large studies on fat dissolving injections have not demonstrated any permanent side-effects of the treatments.
