Can Radiesse Be Used in the Same Area Where Juvederm Voluma Was Injected 9 Months Ago?

Combining Radiesse and Juvederm fillers for the face is perfectly fine.  You can use both these products during one visit to acheive wonderful results.  Juvederm can last up to eight months while Radiesse can last up to twelve months.  If one is placed on top of the other, it will not cause a problem.  Another product that works well and lasts longer is Sculptra.  It works by stimulation of your own collagen production, and is gradually injected over multiple injections.  Consult an experienced injector to see what your best options may be. 

Radiesse can be used in the same area as Juvederm without any problem.  I frequently use the two products together in the midface area.  Generally I find Radiesse a more effective deep filler and Juvederm or Restylane more effective for superficial augmentation.  Radiesse will last longer in this area.  The most important consideration is the ability of your surgeon to obtain pleasing, natural contours regardless of the specific filler used.

Yes, it is okay to combine injectables, especially if your injections were 9 months ago.  However, even at the same sitting, I often use a combination of injectables to achieve the best results.

Good Luck.
