A double chin can appear due to extra amounts of fat in the area or due to loose, lax skin and can make people look overweight and older than they really are.
The excess volume in this area can be made up of a number of factors including:
The term ?jowls? describes sagging, loose skin below the jawline, which most people develop with age.
As we age, our faces can get rounder and develop a jowl-like appearance but this isn?t necessarily due to putting on weight. Women can lose bone density after the menopause and fat on areas high on the face can also be reduced, causing the chin and neck areas to lose youthful definition.
Both sun-damage and smoking can accelerate the ageing process, resulting in a loss of the skin?s elasticity and collagen. Genetics can play a part in the development of jowls, but it has also been suggested that sleeping on your front or side consistently may cause jowls to form over time.
