Double chin is released skin.
Double chin is a more visual issue - many women experience discomfort because of it.
Medically speaking, a double chin isn’t usually a sign of a health problem,
It is nothing more than a layer of fat that has formed under the chin. When that layer becomes substantial enough, it forms a wrinkle that creates the appearance of one or more extra chins.
Common causes of a double chin:
- Excess fat
- Aging skin
- Poor posture
- Facial structure
- Genetics
Correction of the double chin is possible with surgical intervention. In addition, the Center for Aesthetic and Plastic Medicine may offer an instrumental and injection method (jointly).
If the double chin is caused by obesity, along with losing extra pounds, you will also get rid of the fat accumulated under the chin.
