The nasolabial fold is the deep crease running from either side of the nose down towards the corners of the mouth. This crease becomes more noticeable as part of the natural ageing process. Fat is lost from the cheeks, reducing skin volume and making this fold appear deeper. Repeated smiling or having a “big smile” may result in permanent, deep creases in this area.
Marionette lines (corner of the mouth) are long vertical wrinkles that traverse from the corners of the lips to the chin. The name is derived from Marionette puppets that have faces with long vertical creases. These creases could give a grim or sad look to the face. These lines occur with age, smoking and genetics and can progress to form jowls later on.
It is possible to lift these corners with dermal filler by adding volume and anchoring the corners higher up.
