What is the difference between leg lifting and thread lifting?

I'm starting to get a little worried about facial sagging, so I'm looking into lifting procedures. I'm trying to decide whether to look into Ondari lifting or thread lifting.

What I want is not a drastic tightening effect on my face, but just a slight improvement in the sagging of my cheeks and a naturally defined jawline. The sagging isn't severe yet, but I can feel that my skin has lost elasticity compared to before, so I wanted to try getting some treatment.

I understand that Ondari lifting improves elasticity and facial lines by delivering energy to the skin or fat layer, while thread lifting is literally a method of inserting threads to pull up sagging tissue. I am curious about the actual difference in effectiveness.

In particular, since I don't have much facial fat, I want to avoid losing too much fat or my cheeks sinking in. I am also wondering what other factors I should consider in this case.

I think thread lifting shows immediate results but might come with drawbacks like swelling, bruising, or a foreign body sensation, whereas I am curious to hear the experiences of those who have actually undergone it regarding whether the changes from leg lifting appear relatively naturally.

If anyone has received one of these two procedures due to early facial sagging or a blurred jawline, please share your experiences regarding the differences you noticed, as well as the naturalness and satisfaction you felt after the procedure!
