Redness on nose 3 months after filler (photo)

i have had my fillers in my nose since june. i have gotten fillers in my nose about 4 times before and never experienced this. My nose is STILL red at the tip from where it was injected in JUNE. i asked my plastic surgeon if it was some for of necrosis and he said no. then i looked it up online and it might be something like hyperemia or something. if it is, how do i get rid of it????
