Please let me know if I qualify for the double chin lift recommendation.

Perhaps due to my recent habit of looking down at my smartphone, my chin has been sagging and my double chin has gotten worse. Every time I take a photo, I can see the skin under my chin folding in two, so I’m constantly busy using photo editing apps to slim down my jawline. I don't even weigh that much, but the fat is concentrated specifically under my chin, making my face look bigger and giving me a dull impression, which is causing me a lot of stress. I’ve seen many reviews on online forums saying that the double chin lifting procedure at Maypure is very effective, so I’m wondering if a case like mine would be effective. It doesn't seem like my bone structure is wide; the problem seems to be purely fat and sagging skin. I’ve tried doing gua sha massages at home every day, but my chin fat hasn't budged at all, so I think a procedure is the only answer. Haha. Are there any people with severe sagging like me who have had a double chin lift and seen their jawline become smoother? I’m also curious about the mechanism—whether it reduces fat or lifts the skin by improving elasticity. I’m posting this to get some information before visiting the clinic. I look forward to your honest advice on whether a double chin lifting procedure is the perfect fit for me!
