There are many different types of changes that can occur to the neck and chin when a person ages. Sometimes, the problem is genetic. Other times, it is related to facial movement and general aging.
One common change that patients could experience is the double chin. People who have a double chin often notice it on photos. Some patients will wear scarves or high-necked jumpers just to cover their double chin. With this type of problem, there is often a very strong genetic element. Patients will say that their mother faced the same problem. Sometimes, people want surgery to prevent the problem from progressing.
Please note that a double chin usually comprises of two components. Usually there is excessive fat, as well as the second component being loose skin. Therefore, a specialised solution may be required to correct the problem.
