Consensus on updated treatments for neck rings/bands/folds? (Photos)

I've never been overweight, but I've had horizontal rings of skin around my neck my whole life. I've seen similar questions, but I'd like some cohesive, up-to-date information. 1. Are there any emerging treatments to get rid of them? 2. What are the most effective/longest lasting treatments? 3. How effective are lasers on darker skin tones? 4. Re: invasive methods, is the potential for scarring greater for darker skin tones? 5. Average costs? I appreciate any and all advice. Thank you!
