What is the best and effective way to remove unwanted fat on the chin?

Double Chin: It may be very difficult to lose the fat in your double chin. If weight loss by diet and exercise doesn't do the trick, you may want to consider liposuction or platysmaplasty, or even a facelift. At you age, if you don't have excess skin, liposuction is likely the best place to start. See a good, reputable facial cosmetic surgeon who can give you specifics regarding what's in your best interest.
