Indented, pitted scar on my nose? (Photos)

Hello, so I have a 4 year old indented scar on my nose from a massive pimple. My issue is I do not want to get a full face laser resurfacing or full face chemical peel for just this one spot. I am considering anything really, I am looking for the best improvement (fillers, subcision, tca cross, laser (profractional, Mixto co2 can I get a spot treatment?) Any advice would be greatly appreciated Thank you
