Dr. Terence Tan says: It can occasionally happen if too much filler is injected or if the filler is not suitable for the nose. Check with your doctor on the filler most appropriate for the treatment area. Certain fillers, like Radiesse®, have minimal propensity to migrate. But in the rare instance that the filler migrates, there is a dissolving agent that we can use to dissolve the migrated hyaluronic acid filler.
