Post Fibrous Popule Removal: Best Treatment for a Scar?

On November 29, 2010 I had a fibrous popule removed from the left side of my nose. There used to be a dent a few months after the removal, but now the area is flat for the most part. However, it is still dark\redish and noticable. What are some of the best things I can do at this point to reduce the dark\redish appearance and get the area to blend in with the rest of my skin? Some people have suggeted I used Maderma but I am not sure what to do? Thank you.
