How Long Does Radiesse Last?

Hi Anon,
I do not use Radiesse under the eyes in the tear trough hollow because unlike hyaluronic acids (Juvederm, Restylane, and Prevelle Silk) it is not reversible. Sometimes hyaluronic acids can be used to camouflage the "bumps" until the Radiesse dissolves. Radiesse can last up to 9-15 months. Consult with your physician or with a physician who is very experienced at injections in this delicate area. The good news is that the Radiesse will eventually disappear.
Dr. Jeffrey Hoefflin's answer to your question is most complete and I agree with what he has said. I hope that your problem resolves most quickly. Be well.

Experience
shows that Radiesse lasts a year or more in many patients. Radiesse
provides many of the same plumping advantages of the HA fillers while also
providing the volumizing effects of Sculptra.

I agree with much of what has been said on this topic by previous authors.  The effect of Radiesse slowly goes down with time but can last for over a year.
