Dr. Spero Theodorou, the founder and surgical director of bodySCULPT®, has raised concerns about the safety of dermal fillers. His study suggests that dermal fillers may block lymphatic channels in the face, which can have potential long-term effects on the immune system’s functionality. The study used a special camera to track the movement of a dye injected into the faces of women who had undergone facial filler procedures. The findings revealed that the dye accumulated in areas where it should have been drained by a functioning lymphatic system. Dr. Theodorou has stopped offering dermal fillers at his practice, and is urging people to consider the risks before getting them. While some experts opine that dermal fillers may block lymphatics in localized areas but do not pose systemic threats to the overall immune system, the debate over the safety of dermal fillers continues. The lack of regulatory oversight in the industry and recent cases of severe complications have prompted a reevaluation of their safety.
