I had a non-surgical rhinoplasty on my nose (revolax sub q dermal filler) on Sunday. Immediately after I bruised very slightly from where a cannula was inserted. Today I went to have some of the filler dissolved because I didn't like the result. The bruise has darkened and turned a sort of purple (see photo - top bruise is the one I am referring to - the bottom marks are from the needles for hyaluronidase dissolver). I have scared myself ready reviews about necrosis. Could this be a vascular occlusion?
