Can Face Tite be used for marionette lines?

I would not recommend using FaceTite directly over marionette lines because there is a nerve near there which could be affected and cause weakness in movement of the mouth.  However, when FaceTite is used to tighten the lower face, it can improve marionette lines even though it is not placed directly over them.  

Any areas on the face and neck with saggy skin can be treated with FaceTite. This includes the double chin, the neck, the jowls, the jawline and mandible, and marionette lines as well as other areas with deep lines and loose skin.Kenneth Hughes, MD ABPS Board Certified Plastic SurgeonLos Angeles, CA

FaceTite can internally tighten the skin in the lower face and neck. After all the skin has been heated and contracted, we shape the neck with liposuction to give definition and remove stubborn pockets of fat. In one quick treatment, we can tighten skin, remove fat, and contour the lower face, jawline, and jowls with only a weekend of downtime.For marionette lines... I recommend fillers to soften the lines themselves and also lift around the mouth and cheeks to build underlying anatomical support. In our practice we combine Sculptra with other fillers "layered" on top and lasers, skin tightening treatments such as Thermage, Fractora, and Renuvion (J Plasma), thread lifting, and peels to get the most conservative, natural look. 
Keep in mind that combination approaches will give you a more significant improvement as opposed to a single procedure. I recommend getting a consultation with a board-certified cosmetic dermatologist and facial sculpting expert. Best, Dr. Emer

Facetite can be used to treat the marionette lines. The treatments are done just lateral to the marionette lines to tighten the skin and reduce the "step off". I have often combined facetite with liposuction of this area to get even better results
