What Happens to Radiesse over the Long Haul?

Radiesse's duration depends on the location of injection with areas of high mobility (nasolabial folds) lasting significantly less than immobile areas (cheeks).  Radiesse is a stimulatory filler which is replaced and turned into collagen over time.

Hi jf.  Generally speaking we tell our patients that Radiesse is going to last in the neighborhood of 9-12 months.  We like to err on the side of a conservative estimate.  Better to tell a patient it will last 9 months and have it last 12-15 than vice versa. 

As for what happens to the product, it is slowly absorbed and dissipated by the body over that time.

When Radiesse first came to the market the company was making claims of it lasting for much longer than it actually has proven to last. Clincially we see that many patients have Radiesse last close to a year, or slightly more, but we also see that with Restylane and Juvederm too. The best clinical effect though, dissipates sooner and further injections are often done closer to eight months rather than waiting for it to wear off completely.
