What would be the best treatment for a deep cat scratch on the nose? (Photos)

Two years ago I was scratched badly by a cat. The gash on my nose was deep and has not been stitched up. I applied silicon for few months and, although I can see some improvements, even after 2 years the cut is still very visible. I want to fix it. I have been suggested two options and I would like to know which one is the best for my specific case. option 1. laser to reduce the cut option 2. FELC Plasma Machine to reduce the cut which would you recommend? Thank you.
