Double chin lifting, which is better, InMode or contouring injections?

I'm worried about my double chin, and since people around me have been talking a lot about InMode and contouring injections, I'm looking into which one is better. I've heard that InMode tightens the skin, while contouring injections dissolve fat, so I'm curious about the difference. According to reviews from others, InMode is less painful and swelling subsides quickly, whereas contouring injections can cause some bruising or swelling, so I'm told to be careful. I'm hesitant about surgery and want to get rid of my double chin with a procedure, so any reviews or advice from those who have chosen either InMode or contouring injections would be a huge help!
