When will Radiesse be gone? Could it make my face look fatter around the jaw line/lower cheeks?

Hi, I got Radiesse injected 7 months ago. 2 questions: 1. When will my face look like it did pre-injection? I thought it was two years for it to be gone, but a doctor told me that it will look 100% like it was when filled for 2 years and then, after two years, it slowly dissipates. Which is true? 2. Can Radiesse make the lower cheeks/jaw area look fatter? I'm slimmer, But my face looks much fatter and has no contours now. Can radiesse make tissues well and look like fat?
