The issue with loose skin on your neck is that it has been stretched out from excessive manipulation over time. If you have minimal loose skin then some tightening can be done in a limited fashion with lasers. If there is an excess of fat and the skin is tight, the a technique called Precision Smart-Lipo would be a good treatment. However, with loose skin and excess fat in the neck, the best approach is a neck lift. Often this involves an incision behind the ear and in some cases the incision extends in front of your ear. However, it is well hidden. The underlying muscle is tightened and the excess skin is removed.
