Is the painless advantage of Ondari Lifting really certain? lol

I haven't gained any weight at all, but my skin elasticity is dropping so rapidly that my facial contours are collapsing, and sullen cheeks are sticking out around the corners of my mouth ㅠㅠ The skin under my chin folds even when I'm just sitting still, so I feel totally depressed and get angry every time I look in the mirror lol. I don't think contouring injections will be able to fix this sagging skin at all, so I'm looking into lifting machines that really tighten the skin, but lately when I look at online communities... Leg lifting So many people recommend this! They say it doesn't hurt at all and just feels refreshing. Would it be perfect for faces with a severe double chin like mine? Compared to other lifting machines, is it possible to go back to daily life immediately without bruising or swelling? Leg lifting The biggest merit I heard that... please leave some genuine testimonials to see if it's true ㅠㅠ And to definitely get the lines sorted out... Leg lifting I'd appreciate it if those with experience could leave a comment on whether I need to get treatments consistently at intervals of a few months to get a V-line.
