Marionette lines
Marionette lines are long vertical lines that laterally circumscribe the chin.[1] They are important landmarks for the general impression of the face. Marionette lines are an ideal target for Botox treatment, often in addition to injectable fillers.[2] Marionette lines appear with advancing age and some people never get them, depending on facial structure and anatomy. They tend to appear as the ligaments around the mouth and chin relax and begin to loosen and sag, and fatty tissues of the cheek deflate and descend during the aging process. It can be difficult to get rid of them, but they can be minimized with facelifts that lift cheek tissue away from the area of the mouth combined with synthetic facial fillers, or with facial fillers alone.
Difference from wrinkles
Marionette lines and wrinkles are two different types of folds or fine lines, yes both of them are a result of the aging process, both make your face look older, but the one major difference is that marionette lines give you that unhappy or mad expression where some people may misunderstand your face expressions just because of marionettes.
