What Are my Options for Removing a Nose Piercing Scar?

I pierced my nose on Aug 4th 2012 and after four months of dealing with bumps and inflammation I decided to remove it. The piercing left a scar on my nose that is much larger than any of the other piercing scars I've seen. Also, I think I might have hurt the area around it by cleaing it too much with tea tree oil. Basically, my right nostril is a mess. I was wondering what type of treatment would work in order to make the scar less visible.
