I Want Chubbier Face, What Type of Filler?

Voluma is a new poroudct from Allergan, and follows the Juvaderm Ultra and Ultra Plus product family line.  Voluma lasts 2 years and is FDA Approved for filling the midface.  

Thank you for your question. Sculptra is a good product for this effect. It lasts 25 months in most cases, and if properly prepared and placed, can be very low risk. See a Board Certified Dermatologist or Board Certified Plastic Surgeon for this procedure. I hope this helps.
