double chin

A double chin is the appearance of excess fat or sagging skin below the chin, creating a secondary fold or layer. It often results from a combination of factors such as genetics, weight gain, aging, or loss of skin elasticity. When fat accumulates in the area or the skin quality diminishes, it can cause the chin to appear fuller or less defined. Lifestyle choices, genetics, and aging contribute to its development. Treatments range from lifestyle changes and exercises to medical procedures like liposuction or skin tightening, depending on the cause and severity.
