Best filler for marionettes lines? I am a 65 year old female with marionette lines which age me. (Photo)

Marrionette lines are frequently treated with fillers. The choice between Restylane vs juvaderm, is frequently a injectors preference. It's better to have something with a higher G prime, which is more stable. Restylane is my preferred choice for that area. This will provide structure. 
However, you need to be cautious. If you were to totally correct that area for your case you might end up with a too much fullness there. You have significant facial ptosis or drooping that's causing the lines. So a facelift would likely give you the best correction. If that's too far on the spectrum for you to consider then doing fillers conservatively will improve the appearance. 
I would recommend seeing a board certified plastic surgeon, which will be able to offer you a full spectrum of treatment options.

A combination approach will give the most improvement. I recommend fillers (Juvederm, Radiesse, Bellafill) for the folds themselves but also lifting around the mouth and cheeks to build underlying anatomical support. In our practice we combine sculptra with other fillers "layered" on top and lasers, rf treatments, J Plasma and peels to get the most conservative natural look. Please see a facial sculpting expert.
