Is it safe to have Juvaderm Voluma injection in cheeks if still might have some Radiesse in cheeks?

Yes, it is fine to mix fillers in the cheeks or other areas of the face.  In my Orange County Dermatology office we often inject different fillers in the same area, sometimes even on the same visit.

It is safe to inject Voluma in the mid face at the same site of previous Radiesse treatment.

There is no problem having Voluma injected into the cheeks if there is still some Radiesse present.  You should be aware however, that whatever amount of Radiesse that is still present will continue to resorb with time.  So, the result you obtain after the Voluma will continue to go down some as the Radiesse goes away.  

As long as you've healed well after the Radiesse this would not typically present a problem. Radiesse is actually reabsorbed over time and replaced with collagen. Depending upon how far out you are from your Radiesse treatment, it is possible that the product is no longer present and has been replaced by your own collagen.

Thank you for your question.Yes, it is common to have one filler, such as Voluma, added when you already have had other fillers.  Make sure you tell your injector/provider all the injections you have had so that he/she is aware prior to proceeding.I hope this helps.
