A double chin isn’t generally an indication of a health concern, many people find them unattractive and believe they can impair your self-esteem. Although there are a variety of explanations for double chins, they are frequently linked to weight increase. That’s why, even if they’re at a healthy weight or in the process of reducing weight, some people might develop a double chin.  

Genetic predisposition to a double chin can run in families where skin loses elasticity has been an inherited trait. It can also happen as you age and begin to lose muscle. Another reason your skin might sag is poor posture as this debilitates the muscles around the neck and chin area. This has the same impact as aging on the fat around your neck.
