One thing they don't say about Radiesse. It has Methylcellulose in it. Some people are very allergic to it. It's been almost 4 weeks and I am still dealing with the reaction. Radiesse has a white translucent color and that is methylcellulose. All I can say is it almost killed me. 2.5 weeks of prednisone. Then a z pac of antibiotics. Now, I am having redness in my face (possibly hives coming on). I haven't been able to fully hear. And for one week I had no sense of smell. The manufacturer needs to add the part about methylcellulose when advertising this. It's been a very scary ordeal and I don't know what the outcome is going to be.
