Quick Answer
Filler Overfill Syndrome (FOS) is a clinical condition in which accumulated dermal filler—often from multiple sessions over time—creates unnatural volume, distortion, or tissue changes in treated areas. It affects patients who have received hyaluronic acid or other filler types, regardless of original provider. Correction typically involves staged hyaluronidase dissolving, structural reassessment, and careful volume management. At ID Cosmetic Clinic in Markham and Toronto, FOS correction is personally performed by Dr. Dan Xu, M.D., with individualized treatment plans spanning multiple sessions over several months.
