Extended Definition

A double chin comes from submental fat, the angle of your neck and head, and how much your chin projects. The biggest lever is overall body fat — you cannot spot-reduce under the chin. Posture is the fastest win: a forward head position folds the soft tissue under the jaw and creates a double chin even in lean people, especially in photos.

Why It Matters

It is one of the most common appearance complaints, and most of the fix is free.

Mistakes To Avoid
