Skin Tightening + Fat Loss Q&A

i watched a video on youtube and this dr. said RF causes fat los and does not tighten the skin. Now i am afraid to even try it.

I am would like to tighten my thighs, I am concerned about the possible fat lose from RF. Does it cause fat lose? I am more looking to smooth my cellulite.

I had Exilis Ultra 3 years ago and had noticeable facial fat loss after (particularly at the temples and cheeks), which caused some sagging at the jawline and neck. I tried Kybella to deal with the neck, and it made things worse... I'd like to tighten my skin without creating additional fat loss, and it's not severe enough that I'd want a lift as of yet. What would you suggest is the safest, proven modality? Thanks in advance for your informed opinions!

I've seen two doctors. One said I have fat loss and recommended fillers in my cheeks and temples while the other said I have a bit of skin laxity and recommended skin tightening treatments. I don't know which one is more suitable. Do I look like I have fat loss or lax skin?

What is the best procedure to firm cellulite/back of thighs without fat loss? I do not have the best skin laxity so would like to avoid fat loss and just smooth or tighten the area.
