Temporary injectable wrinkle fillers, like Juvederm, Restylane, and Belotero are usually made up of different kinds of natural or synthetic materials that break down and are absorbed by your body. Typically, they last from 3 months up to a year.  Some, like Juvederm Voluma and Radiesse last a little longer (up to 2 years).  Therefore, the wrinkle correction is only temporary and most often you need to pay for repeat injections several months after the initial treatment to maintain your wrinkle correction.
Bellafill has unique microspheres so it works differently—the microspheres are not absorbed by your body and provide a support structure for long lasting, natural looking correction.
