What would be best to get rid of the back roll at the bottom and the sacral fat pad? Lower body lift? Airsculpt? Lipo? (Photos)

These are two different problems. Sacral fat is liposuction. The back roll is liposuction with a back lift.

Good luck

Based on your nicely posted photos, even though they’re under exposed, you have fat excess skin back rolls and sacral rolls. My recommendation would be to start with the stage when surgery of superficial lip sculpting with plasma or Endo lift laser combination, expect fees to range from $5000-$10,000. If there still is excess skin can try non-invasive procedures like body type Endo laser J plasma or go for skin excision with potential scars. Best of virtual consult with before proceeding. Regards.
