Juvederm Ultra three injected in nose, how long for it to metabolise and will scar tissue form? Is Hyaluronidase an option?

I had juvederm ultra 3 injected over a month ago to improve a nostril scar. He injected 0.7ml and it went along the side of nose causing a lump. He injected twice, once from inside of my nostril and from above. I have heard about scar tissue forming, this is my first time can this happen. How long will it take for it to dissolve as I heard for the nose it can take years Hyaluronidase I heard it is less effective on juvederm and breaks down your natural HA more than the filler, is waiting better?
