How to Decide: Chin Lipo or Jaw Fillers for Double Chin? (Photo)

I have a slim physique but have noticed what looks like excess fat under my chin. I’m considering getting chin liposuction to address this, and then proceeding with chin/jaw fillers for improving my jawline and addressing jowls. I’ve seen before and after photos from online research, particularly for chin/jaw fillers. However, I’m uncertain if just fillers would be sufficient to fix the double chin, or if I should go ahead with chin lipo before the fillers. Advice would be greatly appreciated!
