Radiesse can be manipulated immediately after placement, and for a period of time during the first day. Some docs argue whether to have patients massage or not, and for a half an hour to half a day. In short, we have no clear indication as to how long it is malleable.
After a week, there is no additional movement anticipated. The body has formed small collagen responses around the micronized product, effectively stabilizing the injectable and establishing soft tissue augmentation from your own tissue response. So it's not moving. If you still feel some localized fullness, I still suggest massage in order to soften this collagen response. It still might help. If you are concerned about the distribution of the product, follow up with your physician. They might be able to inject a dilute form of kenalog, again to soften the body's collagen response.
