A double chin refers to a layer of fat forms below the jaw, which protrudes thickly or overlaps in two. Weight gain or body fat can contribute to develop the double chin. The double jaw is also affected by the natural aging process which brings the loss of the elastic tissue in the skin. A medical team in the Arumdaun Nara Dermatology Plastic Surgery recently announced the results of a clinical treatment that improves double chin by fat cell destruction therapy in the American Academy of Dermatology (AAD). This treatment is a non-surgical procedure to effectively remove submental fat. The energy is used to lower the submandibular region below a certain temperature to destroy the fat cells. Applying cooling energy to areas with high fat, such as under the chin, can lead to self-extinction of fat cells that are vulnerable to temperature, effectively reducing the fat. It is advantageous to be able to enjoy daily life with little or no side effects compared with liposuction or incision.
