3 months after nonsurgical nose job, nose is still red - should I be concerned about possible necrosis? (photos)

I had a nonsurgical nose job (filler) 2-3 mo ago. The tip of my nose has been red ever since the procedure and I am concerned because it is not improving at all. I can see some little darkened capillaries and am also nervous about a little dark spot I saw today. If this were a serious complication leading to necrosis would it have happened already and now it's just cosmetic? Or should I go get it dissolved? The injector said sometimes redness takes forever to resolve but I'm concerned.
