Injecting facial fillers into the skin layers of the dermis and middle dermis is a popular non-surgical facial procedure. However, it is important to be aware of the potential risks associated with this procedure, such as accidental injection into blood vessels, which can cause blockages that restrict blood supply to tissues. Additionally, overmolding the filler can compress the filling into a foramen, leading to compression of a nerve that causes paresthesia. In order to minimize these risks, physicians should fully inform patients of the potential risks associated with the procedure, know the signs and symptoms of accidental injection of facial filler into blood vessels, and have a plan to treat patients if this occurs.
Furthermore, it is important to inject the right filler at the right level to the right patient and also at the right time. There are seven danger zones for facial nerves that should be avoided when injecting fillers into the face. The FDA has asked manufacturers of facial fillers to update their labels to include additional warnings about the risk of accidental injection into blood vessels.

By following these guidelines and taking all necessary precautions, physicians can help ensure that their patients receive safe and effective treatments.
