I have a double chin; would CutSlim Injection be a good fit for me?

I am really worried because, even though I don't have a very chubby face, the skin under my chin is particularly saggy and bulges out like I have a hard candy in my mouth. When I take photos, the boundary between my jaw and neck disappears, making me look dull and giving me a bad impression; it is a huge source of stress. Home care using gua sha or bandages doesn't seem to be working at all, so I am considering getting CutSlin Injection, a contouring injection that is said to destroy fat. I hear it is a "gentle" injection without steroids, so I want to know if someone like me, with severe sagging skin under the chin and a chronic double chin, is exactly the right candidate for CutSlin Injection. I am also curious about how long the bruising and swelling last after the injection. I am waiting for advice from those who were deemed eligible for CutSlin Injection and achieved a defined V-line!
