What can be done to help scarring of line across nose and depressed nasolabial lines?

After years of using my nail to scratch across my nose from one end of the nostril to the other, a visible, dark line formed running across it. I have tried chemical peels & they have done nothing to make the line go away. It has also caused depressed smile lines to develop close to my nose. I have seen pics of reconstructive surgery to remove nasal skin and replace it with a skin graft. I have also researched fat grafting to help w/ the nasolabial lines.Would these or any other techniques help?
