I have a lot of fat under my chin; am I a candidate for a double chin recommendation?

I worked hard on my diet and lost weight, but I'm going crazy because the fat under my chin just won't go away. I get a double chin even if I just tilt my head down a little, so I can't survive taking photos without a photo editing app. I really want to get rid of this stubborn double chin fat, the main culprit ruining my face line, with the help of a medical clinic!

I've tried contouring injections and InMode, but the effects are only temporary and the results just come back. So this time, I'm thinking of trying V-Olet injections, which destroy fat. I heard that since it destroys the fat cells themselves, the yo-yo effect is less likely and you can expect semi-permanent results. Would someone like me be the perfect person to recommend for a double chin?

They say it is most effective for fatty double chin caused by weight gain, but seeing the thick lumps under my chin, I think it really is 100% fat haha. I saw reviews saying the swelling lasts quite a while and makes you look like a toad with a scarf, so I'm wondering if it significantly interferes with daily life. I'm also curious if this injection definitely falls under the category of recommended treatments for a double chin.

Surgery for liposuction is too scary and the long recovery period is a burden, but if I can get a slim V-line with just one injection, I think I could grit my teeth and endure the swelling. If my jawline becomes more defined, my neck will look much longer and my features will appear more distinct, right? I'm waiting for advice from those who have successfully gotten rid of that annoying double chin!
