Extra fullness beneath the chin is an aesthetic concern for many. This condition—submental fullness—is commonly called a “double chin.” Both men and women may be affected by submental fullness. In a recent survey, one in four people were concerned about the appearance of their double chin.
What causes submental fullness? Weight gain, genetics and aging. However, it may result from the accumulation of subcutaneous fat under the chin. Because aging and genetics can contribute to submental fullness, sometimes diet and exercise alone may not help.
