double chin...

Really off topic but it's something that bothers me everyday and I have low self esteem because of it. I have a double chin and I'm not over weight, I'm actually very skinny so I guess I just got the double chin from genetics. Does anyone know how to lose it, or has anyone had any procedures done that took it away??? I tried coolsculpting because I had read really good reviews on it, but had 2 treatments and NOTHING changed. I spent almost $2,000 (basically my whole savings) for nothing. It's just something that bothers me everyday and I get really bummed out when I see myself in the mirror. 😔
