Dissolving
Hyaluronidase starts working immediately, once injected into an area of unwanted hyaluronic acid dermal filler. Initially, the treatment area may feel a little swollen for a few hours. Possibly red, slightly tender, or warm. Although it starts working immediately visible results from hyaluronidase treatment will take 2-3 days to show.
If you had a previous treatment performed elsewhere and feel your results are unsatisfactory, or you feel you may have filler migration, then it is time to remove them.
