Marionette lines are the lines / folds which start at the mouth corners and go downwards ending at the jawline. They are caused by repeated movement of the mouth and the loss of fat and skin elasticity that occurs naturally as part of the ageing process. Lost skin volume causes lines to turn into deeper creases.
Dermal fillers can remove the “sad” look caused by marionette line wrinkles and nasolabial folds by restoring lost volume.
