Cellulite and uneven fat bulges: Is Venus Legacy & Injection Lipolysis the right thing for me?

I had liposuction over 10 years ago, aswell as a gentle laser liposuction on the back of my thighs1 year ago and Im still suffering from cellulite and saggy skin on my butt, aswell as uneven fat bulges just below the butt.I would love to try a non-invasive method. I was recommended to do Venus Legacy ( tighs) and Injection Lipolysis for the below the buttock area. Is that the right thing to do, can it be combined or would you recommend another method?
