There really aren’t any good non-surgical options to get rid of excess neck skin. Laser resurfacing and chemical peels do not work, and unfortunately the wonderful nonsurgical (injectable) tools we have that work really well for the face, work poorly for the neck. Neck liposuction does not work either, as that only addresses excess fat, not excess skin.
The most effective way to remove excess neck skin is to have a neck lift procedure. During this procedure, tissue and excess skin are tightened to rid patients of the aged look that can accompany excess neck skin. Plus, the longevity of a neck lift can last beyond even that of a face lift, if properly performed. Again, finding a reputable and experienced doctor is crucial in achieving the results you desire.
