My jawline is sagging and my double chin is getting worse. Will getting InMode make my face look as slim as a bone? ㅠㅠ

It’s not like I’ve been eating a lot lately, but maybe I just can’t beat gravity as I get older. Just like in the photo, my jawline has become really dull and the skin feels like it’s sagging down. ㅠㅠ Even if I just tilt my head down slightly, the skin under my chin folds in two, creating a double chin. Every time I look in the mirror, I look so wide and flat, and it feels like I’m going to get depressed. Haha. I don't think getting just a little bit of contouring injections will fix these unsightly sagging fats, so I’m seriously looking into machine lifting procedures to really tighten the jawline! People around me say InMode is the best for smashing a double chin, and I’m really curious if it will really bring out a V-line jawline for someone like me with plenty of fat under the chin. ㅠㅠ I would also be so grateful if you could let me know if the bruising or swelling goes down after the weekend. Haha.
