It’s not hard to guess where the term came from: look at a ventriloquist’s dummy and the exaggerated, deep furrows around the distressed-looking mouth and you get the idea.  These lines are caused by depleted fat, but the good news is, now the ‘fat’ can be put back and the face can be restored to its youthful volume again.  Effective facial fillers are one of the great recent advances in anti-aging medicine.  Like Botox and any injectable, they should be injected by a Board Certified Dermatologist, who has years of specialty training in the delicate nerves and complex muscles of the face.
