I'm worried about a double chin. Is the CutSlin injection really effective?

I didn't really care about it before, but lately, every time I take off my mask, I'm seriously stressed out because of this double chin that sags like a bulldog's under my jaw.

I've looked into all sorts of contouring injections, but the CutSlin Injection procedure really caught my eye because it doesn't contain steroids, which reduces concerns about side effects or hollowing. I heard it completely destroys fat cells, so can I really achieve a sharp jawline with just injections, without any bone-shaving surgery? I've heard that you usually need at least three sessions to see noticeable results, so I'm also curious how long the swelling and bruising last. If there are any of you who, like me, had a lot of chin fat but achieved a smooth V-line after getting CutSlin Injections, please share your real experiences. I want to read this and go book an appointment right away!
