Will InMode be the surefire fix for my sagging jawline and drooping cheeks? ㅠㅠ

As I get older, it feels like gravity is slowly taking over. Every time I look in the mirror, my jawline doesn't look as sharp as it used to and seems to be sagging. The skin under my chin is also sagging slightly like bulldog cheeks, so even a slight tilt of my head makes me look blunt and wide. Because of this, I find myself constantly covering my chin when taking photos. I've heard that InMode lifting is the most popular and famous treatment for getting rid of double chin fat and tightening the skin, so I'm seriously considering getting it done! However, I've heard it gets very hot and causes severe, bright red bruising under the chin, so I'm a bit worried since I work. How many days does it usually take for the bruising to completely disappear? If anyone has tried InMode regularly according to a schedule to tighten their jawline, please share some information on the actual results!
