I'd like to get a double chin lift. Has anyone seen results?

Lately, whenever I take a selfie or look in the mirror, I've been particularly self-conscious about the fat under my chin. Even if I tilt my head down just a little, my jawline disappears and I can see it folding in two. It doesn't seem like other people are like that... not even my friends...

People around me say that a lifting procedure is the answer for a double chin, so I'm looking into it. I am quite intrigued by the claims that it tightens sagging skin like glue to smooth out the jawline. In particular, I've heard that having a defined jawline makes the face look smaller and gives a much cleaner impression. For those of you who have had a double chin lift, what is your experience? Is there really a dramatic change?

My biggest concerns are the duration of the results and the pain. Also, I'm worried that severe bruising or swelling immediately after the procedure might interfere with my daily life. Is there anyone who has personally received a double chin lift and was satisfied with the results?
