My double chin folds when I lower my head; will my face get slimmer if I get InMode? lol

Lately, I've been eating well and just lying around, so the lower part of my face has gotten really chubby, like a full moon ㅠㅠ. From the front, my bulldog cheeks and deep fat bulge out, making my face look wide and square, so I just sigh every time I look in the mirror haha. I heard that InMode lifting is the most famous for directly destroying chin fat cells and boosting elasticity, so I'm seriously looking into it! Since it uses intense heat and sucks everything out like a vacuum cleaner, I've heard rumors that it causes really severe, bright red bruising under the chin ㅠㅠ. How many days does it take for the bruising to go down after the treatment? Is it bad enough to have to cover it up with a mask when going to work, and is the overall satisfaction with how slimmed down the lower face is really amazing? Please share some vivid reviews from those who have had it done haha.
