A double chin, also called submental fullness, refers to extra fullness beneath the chin that can soften the jawline and change the facial profile. Some people notice it because of genetics, while others see it become more prominent with weight changes, skin laxity, posture, or the natural aging process.
Even in people who are otherwise healthy and active, a double chin can be stubborn and difficult to improve with lifestyle changes alone.
Because submental fullness can involve both fat and skin quality, the best treatment approach depends on what is contributing most in your case. Some patients are looking for a more defined jawline, while others want a smoother transition from chin to neck without surgery.
This page offers an introduction to double chin concerns, including common causes, the areas typically affected, and the treatment options that may help improve contour. A tailored plan is important, because reducing a double chin is not just about removing fullness. It is about supporting balance, definition, and natural-looking results.
