Will Voluma work to fill my marionette lines? I was told it would and would need two vials.

Thank you for your question. I would not use Voluma to treat your marionette lines. Voluma is generally used for areas such as cheeks and nasolabial folds. For marionette lines, I recommend using Restylane Refyne or Juvederm Vollure. Please make sure you seek treatment from a board-certified dermatologist. 

Thank your for your question. 
Voluma is a good filler for deep lines or volume loss. It would be hard to determine what you are a good candidate for without photos or an in office consultation. Just so you are aware, Voluma is packaged in syringes not vials. So please double check with the individual that you consulted with to confirm you are both talking about the same product. Using a combination treatment of dermal filler with a neuromodulator to the depressor angularis oris muscle is a very good correction of mild to moderate marionette lines. Beware of the individual that will inject you, if you have very deep marionette lines with jowling. Injecting this can sometimes make the area appear even heavier. This is when a consultation with a board certified plastic surgeon or facial plastic surgeon is waranted to determine if you are a better candidate for a facelift, or other surgical correction. 
I hope this is helpful
