Hi, I had a BBL in 2019 and revision BBL in 2023. The doctor removed some fat and injected it in the lower buttock, and injected fat in some dents on my posterior thighs. I want to further improve my results with radio frequency, but I don't know which treatment is best. I want to lift my butt a little more and tighten the skin on the backs of my thighs to address some wavy cellulite. I want to do this without melting/killing the new fat in those areas. Which RF treatment would best? thanks
