What's wrong with my chin/neck? I don't have a jaw line and my chin goes down. What can be done to fix this? (photo)

Although its difficult to tell from a photo, you might need muscle modification to the platysma to get a change in shape of your neck, in addition to the traditional liposuction and possible chin implant suggestions.  Its best to get a  personal consultation to determine what you need.

Your chin lacks some definition and contour and can be improved with a combination.  I find that VASER liposuction in combination with ThermiRF are best for contouring the chin in those who are candidates but Kybella can be used as an alternative with or without thermage/ultherapy/exilis.  PDO nova threads can further improve the jawline. See an expert. Best.
