A double chin is an imperfection which troubles many people.
Double chins can be genetic, linked to ageing or weight gain.
Many factors need to be considered in their treatment :
– Skin, the sagging of the skin.
– Muscles ,muscle weakness and muscular flaccidity, notably in the platysmal muscle.
– Fat and excessive adipose tissues.
– Bones, notably the hypoprojection of the chin or ‘weak chin’.
– The sub-mandible salivary gland. This often droops and is rarely hypertrophic.
These factors in combination give the overall impression of a double chin, but excess fat is often, if not always present.
Excessive fullness around the chin and the neck gives the impression of a second chin with loss of definition of the jaw line, and it can be very ageing.
On the pictures we can see the difference on the oval and the neck without and with double chin:
- Chin and lower jaw are well drawn, the neck is thin and below the chin there is no excess fat.. (Picture a).
- The chin is hypoprojected , mandibular line is poorly designed and under the chin there is excess fat. (Picture b).
