Excess fat and puffiness around the neck is usually seen around the neck. There are two places where it gets accumulated. One is just under the chin called the double chin or the submental area. That is best treated with liposuction. The sagginess or puffiness is caused by a muscle just under teh skin called platysma. This in the initial stages can be treated by botox injection. When it is advanced the only option is either to pull it up with the help of threads called thread lift or by minimal access cranial suspension or what is called neck lift.
