Will I definitely see the effects of InMode on my double chin?

I haven't gained much weight, but I'm posting this because I'm stressed out seeing how saggy my chin looks every time I look in the mirror lately. As you can see in the photo, my double chin overlaps severely even when I just tilt my head down slightly. People around me say that the InMode procedure is the surest way to get rid of a double chin. However, since I don't have much cheek fat, I'm worried about potential side effects like sunken cheeks if the treatment isn't done correctly. I'm curious if the InMode treatment really shows noticeable results for sagging chin skin like mine. I want to know if the lines actually improve smoothly beyond just a temporary reduction in swelling, and I'd like to know the satisfaction levels of those who have suffered from similar sagging issues. Please share your experiences with the InMode treatment if you've tried it yourself!
