I am curious about treatment methods for a double chin.

I am on the thinner side, but at some point, I suddenly started noticing a double chin, which has become a source of worry for me. I used to think that a double chin typically required weight loss or contouring injections. However, after doing some research, I learned that for people like me with little facial fat, the sagging might be due to a loss of skin elasticity. I’ve heard that lifting lasers like Ulthera or InMode to tighten the jawline, or procedures like thread lifting, are commonly recommended. With so many options and my lack of experience, I’m unsure how to proceed with a consultation. Since I haven't had a detailed consultation yet, I have absolutely no idea which procedure would suit my face shape or how much it would cost, which puts me in a bit of a predicament. Has anyone else undergone double chin treatment for similar concerns? I’m curious to hear reviews regarding the differences between traditional contouring injections and lifting procedures, as well as how effective they actually were.
