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.

Thanks for your question! It is safe to have both Radiesse and Juvederm injected into the same area. Each of these fillers has their benefits, and although these fillers have different compositions and consistencies, they can be used together to give great results. In fact, we often use this combination when treating the chin and jawline! 
I've included a video that reviews using multiple fillers in one area, I hope you find this helpful in your research.

Luckily for us, there are many fillers available today.  Combinations are often injected at the same visit or in subsequent visits without any issues.  Radiesse, perlane, juvederm ultra plus, and sculptra are excellent choices for cheek augmentation, as these fillers offer more "lift."
