The mental crease is a horizontal groove between the chin and the area below the lips. The mental crease can be a single deep groove, or a combination of more than one line or groove. It gets its name because it appears to be a noticeable indentation or “crease,” and it is formed near the top of the chin (mentalis) muscle.
The mental crease can contribute to an ageing puckered look of the mouth area. It can also make an overly pronounced chin look even more exaggerated In some instances where the mental crease is really deep it can make the face appear out of balance .
Anti wrinkle/muscle relaxant injectables are the first line of treatment for the mental crease by most healthcare practitioners. Small amounts are placed into the mentalis muscle, near the tip of the chin.
If the crease is very deep, in addition to this you can also place an advanced dermal filler along the mental crease to help fill in the crease for deeper correction.
