I got a Juvederm injection last week. She gave me vascular occlusion and beginning stages of necrosis. How to stop it? (Photo)

This is a rare but serious complication with fillers.  It looks as if the inferior labial artery was affected based on the photos.  This should be a fairly deep artery that should be out of the plane of injection when treating the lip.  My first point is tat you need to be under the guidance of an experienced facial plastic surgeon, plastic surgeon, or dermatologist.  Although such complications could happen to any Injector, it would be far more preferable to see a Core Trained Physician with knowledge of facial anatomy and blood supply for future fillers.  This complication may lead to objectionable scarring; only time will tell. 

This is an unfortunate complication of filler.  It sounds as though they used hyaluronidase to "melt" it out.  That is the most important thing to do when this occurs.  With a vascular occlusion the skin usually turns white and it can be painful.  This is when the treatment to dissolve needs to start. It is recommended that high doses of enzyme are injected every hour until it appears as though blood flow has returned.  All of the other modalities such as nitropaste, aspirin etc. are not nearly as important as high dose hyaluronidase.  At 2 weeks there is no benefit to adding more enzyme.  You should keep it moist with some topical antibiotic cream.  Warm compresses will also help.  As it heals, you may benefit from some laser treatments to improve the texture of the skin if necessary.   

I am sorry to hear of your situation.  I'd recommend:Lots and lots of hyaluronidase.  Repeat.Nitropaste, aspirin, medrol dosepack.Topical wound care.Even consider hyperbaric oxygen treatments.
