Is a double chin lift effective even if you have no fat?

I didn't usually pay much attention to it, but recently, while taking photos, I've started to be particularly self-conscious about the area under my chin... It looks fine from the front, but it looks like a double chin from the side or when I tilt my head down even slightly, so I'm getting stressed about it.

I haven't gained much weight, so I'm not sure if this is a problem that can be solved with dieting, and people around me have been suggesting that I look into procedures like double chin lifting.

After doing some research, I saw that people with a lot of body fat get it, and those whose jawlines have become blurred due to loss of elasticity also receive it, so I became curious if it would be the right procedure for me.

If anyone has had a double chin lift, does it actually significantly refine the facial contours? I am also curious whether the effects appear immediately or if they change over time.

I also want to know if there will be swelling for a few days after the procedure, and if it will significantly interfere with going to work or daily life.

Rather than making a decision based solely on advertisements, I would like to hear the experiences of those who have actually used the service. It would be really helpful if you could honestly share everything, from what you were satisfied with to what you found lacking.
