A double chin, also known as submental fat ( لغلوغ) , is a common condition that occurs when a layer of fat forms below your chin. A double chin is often associated with weight gain, but you don’t have to be overweight to have one. Genetics or looser skin resulting from aging may also cause a double chin.

there are several ways to treat a double chin depending on the case , from simple injections that dissolve the fat , to minor procedures to take the fat away.
