Information And Treatment
Simply put, a double chin is an extra layer of fat that resides on the bottom of your "real" chin. This gives you the appearance of having two chins, especially when smiling. The especially adipose-laden may even have a triple chin.
Some people have a genetic propensity to collect fat under the chin, even if they are of normal weight. A receding chin can exacerbate the situation.
Age range: Double chins are normally due to excess weight or receding chins. The condition can strike at any time.
