Excess Neck Skin Since Teenager (now 33) - Lipo or Neck Lift? (photo)

Hi there I have always had excess and loose skin on my neck and chin. I have never been overweight, and I have noticed that even those who are overweight do not have loose skin like me. I now want to try to improve this area. How do I know if I am a candidate for liposuction, endolift, or necklift?
