I'm considering a double chin lift. How effective is it?

It’s not like I’ve gained a lot of weight lately, but the fat has accumulated specifically under my chin, so I’ve ended up with a complete double chin ㅠㅠ. Every time I take a picture, my jawline looks blunt and the boundary between my jaw and neck has disappeared, so I’m incredibly stressed about it... I’ve become extremely reluctant to have my profile photographed ㅠㅠ.

No matter how much I rubbed with a gua sha at home, it didn't work, so I'm finally looking into dermatological procedures. I saw on online communities that double chin lifting is the surefire solution for concerns like mine! Will I be able to see a visibly slimmer face with just lasers and a double chin lift, without any bone-shaving surgery? There are so many types, like InMode and Shurink, but I'm curious to know which procedure is the fastest and most certain for a firm, lifted double chin!!!! I'll be waiting for genuine reviews from those who have seen satisfying results!!!
