Morpheus8 settings for loose tissue around marionette lines/nasolabial folds - should I try to melt fat or not? (Photos)

Wondering if I should request a moropheus8 treatment depth that will melt fat for marionette lines? Is deep (3mm+) treatment best to address excess tissue in this area, or will going to the subcutaneous layer make sagging worse? In addition, how deep will cause fat loss? I've read that 2mm is safe, however, I understand facial skin is typically >2mm thick on the face and the machine emits an additional 1mm of radiofrequency beyond the needle length. Is 1mm is actually the safest to prevent fat loss?
