How to remove depressed scar on my nose bridge? (Photo)

When I was 5 years old I cut my nose 2 times with an aluminium plate. I did not do any stiching that time. I underwent septorhinoplasty when I was 26 years old. Now I am 34 years old and I am really worried about my scar. Some dermatologists suggested me to go for skin grafting, PRP with CIT( collagen induced therapy), fat filler etc. Please help me suggest the best procedure to remove my scar completely to get more confidence to live in society.
