Can fillers like Radiesse have a negative effect on the kidneys?

Cosmetic treatment with Radiesse should have no effect on the kidneys.  I am not aware of any of the FDA-approved fillers having any effect on the kidneys.  

I appreciate your concern. I am unaware of any evidence to suggest that Radiesse would affect the kidneys in any way. This filler contains calcium microspheres that provide support to the underlying skin structure to smooth away wrinkles and restore youthful volume. At the same time, the formulation stimulates the body to produce more collagen for additional support. This function ensures Radiesse results are both natural and long-lasting. The filler is concentrated to the treatment area and does not move through the body to impact any vital organs. 
If you choose to move forward with a Radiesse treatment, work with a board-certified dermatologist who has extensive experience working with this product. This will ensure your procedure is both safe and effective for you. 

Thank you for your question.  There are no studies that correlate Radiesse with any negative effects on the kidneys.  I hope this helps but I suggest following up with your primary physician if you have any concerns.
