Submental fat, better known as a double chin, is never a welcome feature. When you look in the mirror or at a recent photo of yourself and notice a double chin, you realize that the excess fat you carry between your chin and neck has changed your overall appearance, and not in a good way. It may make you look older or make your neck look shorter or wider or not even there. https://millennialplasticsurgery.com/chin-liposuction/
