Thank you for your question. Voluma is a very good filler for your cheeks and midface. It is a bit of a larger molecule, so it is usually placed deeper in the skin, (subdermal). The sales people will tell you it lasts about 2 years. In our experience it last about a year and a half. As far as Juvederm Ultra Plus, (which we like for the nasolabial folds), and Juvederm Ultra, (which we like for the lips), the sales people will tell you it lasts about a year, in reality about 9 months. Every person is different so it can last a longer or shorter time period, depending on the patient. It has been our experience that some folks that are hypermetabolic, (in the gym twice a day, etc.), tend to break down Botox and Fillers faster. Our very expressive patients also tend to break down the products faster. Each individual is different. Please see a well trained, experienced injector. Discuss your goals, and you should be able to come up with a plan. Jeffrey J. Roth, M.D., F.A.C.S.Board Certified Plastic SurgeonLas Vegas Plastic Surgery
