What kind of procedure should I get for a double chin?

I've been really worried about my double chin lately.

It's not like I've gained much weight, but there's a noticeable amount of fat only under my chin, so it bothers me every time I take a picture...

I am wondering if I can see results through exercise or massage, or if a procedure is the answer.

If anyone has tried to improve their double chin, could you please share which method was the most effective?
I've seen a lot of people getting things like fat-dissolving injections and lifting, so I'm curious about the actual reviews!

If you search online for what procedures to get for double chin, you'll find many results such as InMode, fat-dissolving injections, and double chin liposuction.

I want to start with simple skin procedures instead of liposuction.
