Every woman dreams of a slim face, perfect facial features and a long neck. Having a double chin, i.e. a fold of fat under the neck, gives us years and extra pounds. Double chin not only affects obese people, but also slim people. For some, not only one, but two or even three chins are formed. It can appear for various reasons. The main factors are genetic, skin stretching associated with aging, lack of exercise, being overweight and also poor body posture.
