A double chin is caused by an extra layer of fat that develops beneath the chin.
A few different factors combine in the body to create a double chin.
Understanding these factors may help with understanding ways to get rid of the double chin itself.
Age – The skin can start to lose its elasticity as the body ages, which can lead to the appearance of extra or saggy skin that may contribute to a double chin.
Diet and weight – While weight gain is not always the cause of a double chin, it can contribute to it. A diet high in calories, processed foods, and unhealthful fats may influence weight gain and a double chin as well.
Genetics – Genes may play a role in people developing a double chin. Anyone with a family history of skin with little elasticity or double chins might be more likely to develop one themselves.
Posture – Poor posture can weaken the muscles of the neck and chin. This may contribute to a double chin over time, as the surrounding skin loses its elasticity when the muscles are not used.
