A double chin forms due to genetics, aging, and weight gain. But, as it turns out, there’s another reason: improper tongue posture. The good news is that it’s possible to get rid of this physical feature. Younger people, with skin that is tight, can improve their face contour dramatically after removing fat. Here at Bodyrelated, we’ve figured out what we’ve all been doing wrong. Now it’s time to correct your tongue posture and finally get that gorgeous jawline you’ll keep forever. What we usually call a “double chin” is the fullness that forms under the chin. We all have a bit of fat there, and it’s normal. However, our platysma muscle, which connects the neck to the chin, can weaken. In this case, more fat can get accumulated here, causing the fullness. This extra fat that forms above the platysma under our chin is called the “pre-platysmal fat,” and it’s what creates the double chin.
