Is this necrosis? What do I do? 1 day post lip augmentation. (photos)

This is a situation where your injector needs to be seeing you very frequently, ie daily until there is no further fear of progressive vascular occlusion. That said, you photos do not look particularly worrisome.  Nevertheless, make sure your injector checks the area to make sure there is no issue.

Let the dust settle here and find a different injector.  The injector might have done the right thing with the enzyme.  This is hard to know from your story. Getting a hematoma is not the same thing as getting a vascular occlusion from filler.  A simple hematoma is not managed with enzyme.  Generally occlusion causes severe pain, an disturbance in the circulation to the skin well outside the area where the filler is being placed.  Certainly from the picture you have posted, you should rest comfortably, that these does not appear to be any dusky, dark discoloration.

I recommend following up with your injector today. It can take a series with hyaluronidase to dissolve filler. Best, Dr. Emer
