Can Radiesse migrate?

Fibrous septa provide a dense attachment between the dermis and the underlying subcutaneous fascia of the face.  Injection in the subcutaneous plane is unlikely to lead to migration of a stimulatory filler such as Radiesse.  Although migration is theoretically unlikely, it can occur in the rare occasion.

Lady I, From my experience with Radiesse, it does not migrate. Additionally, I have not talked with anyone who has experienced migration either. Radiesse is malleable right when it is injected, but only to mold the shape, not to push in into different tissue planes or locations. I hope this is helpful.

Most likely the injection was in both the cheek and the nasolabial fold and once the sweeling is gone the differential injection will show. The nasolabial fold is a very tight structure and will prevent this migration

It is unlikely for Radiesse to migrate after previous injection.  Once the material is injected, it really does not move around too much unless you forceably push on it, and then only a very short distance.

Radiess is very thick, and not likely to to migrate.  Additionally, scar tissue rapidly forms around the material.  It may be possible at the time of injection or shortly after to mold and manipulate the filler, but within days (if not hours) it pretty much stays put.
