Does anyone know the exact characteristics of Ondari Lifting?

My weight is the same, but at some point, my facial contours started sagging and my chin started sticking out, so I'm really stressed out ㅠㅠ Every time I take a picture, my chin looks like it's folded in two, so I decided I couldn't go on like this and am looking into machine treatments lol. I heard these days they are painless and fast-acting. Leg lifting I see a lot of people doing this; would it be a surefire solution for a chubby face like mine with a severe double chin? I heard the advantage is that it completely smooths out unnecessary lines. Leg lifting I'm curious how long the bruising or swelling on my face lasts after the treatment. If I can get it done on the weekend and go straight back to work on Monday, I want to pay for it right away lol. I'm feeling down because my skin has lost its elasticity.
