Are Stroke, Skin Necrosis, Blindness and Ptosis all Rare complications of dermal fillers?
Stroke is an extremely rare complication of fillers around the eyes. Skin necrosis is rare as well, but less rare. It is caused by occlusion of the blood vessel by a filler injection, and it is usually in the cheeks, lips or forehead. Skilled injection technique, which involves injecting the filler on the way out rather than on the way in, minimizes the risk of this. Also, immediate injection of hyaluronidase can be very effective at stopping the necrosis when the filler is a hyaluronic acid product such as Juvederm or Restylane. Ptosis to the eyelids or brows is a complication of botulinum A toxins like Botox, Xeomin, and Dysport. This is not uncommon but, again, can be best avoided when injected by a skilled injector.
