What Is A Double Chin?
A double chin is an excess layer of fatty tissue under the lower jaw. Both men and women can experience a double chin, and it can happen at almost any age. Medically speaking, a double is called “submental fullness” or “submental liposis.”
Younger people may have a double chin with tight skin, while older people may have a double chin along with loose skin in the neck area. Despite someone’s weight, a double chin can be a source of frustration for people of all ages.
