Can sagging jawline be improved with a lifting procedure?

While researching lifting procedures, what I was most curious about was whether my jawline could change noticeably. Rather than making my entire face taut, I am more interested in having the area below my chin slightly refined and my profile look natural.

I used to think that losing skin elasticity was inevitable with age, but I've heard that there are many ways to manage it these days without surgery. I've heard names like Ulthera, Thermage, and Shurink, but I'm still not sure which procedure is suitable for my jawline.

Does the lifting method differ depending on whether the cause of the blurry jawline is skin sagging or fat? I want to know this first because I am worried that I might choose a procedure that is just famous and not see the results I expected.

Also, I don't want my face to look excessively thin or for my overall impression to change. I think it would be sufficient if I could just naturally refine the lower part of my face while maintaining my current shape. I am a bit concerned because I've heard that getting a lift can also reduce cheek fat.

Before deciding on the procedure, I would also like to check the duration of the effects. I am curious about how many months the results can be expected after a single treatment and whether the skin returns to its original state over time. I would also like to know if there are cases where severe swelling or pain immediately after the procedure makes it difficult to go out.

If I want a natural improvement in my jawline, which lifting procedure should I consult first? Rather than unconditionally strong treatments, I am looking for a method that can be started without burden, tailored to my current skin condition.

For those of you who have looked into jawline lifting, what did you check most importantly during your consultation? Since it's my first time, I have a lot of questions. I would appreciate your advice.
