My double chin folds whenever I lower my head. Will Ondari Lifting help to smooth out the lines?

It’s not like I’ve gained a lot of weight, but unnecessary fat has accumulated under my chin, causing my jawline to thickly fold into two or three layers whenever I tilt my head down even slightly. The boundary between my jaw and neck has completely blurred, so when I take photos from the front or side, my face looks twice as big and my jawline appears dull. Even though I’ve tried rubbing my jawline with a gua sha every day and using contouring bands, the swelling only subsides temporarily; the thick sagging fat and loose skin under my chin remain exactly the same. I’ve also heard a lot of negative things about gua sha. I heard it’s much less painful than Shurink or InMode, but I’m curious if anyone else has experienced the effect of a sharp, tightened jawline after getting an Ondari Lift for thick chin fat and a sagging jawline like mine.
