I have a 6 month old scar on the bridge of my nose, is it a keloid? (photos)

No stitches - just let a scab form. I noticed today with an updated picture that it looks as if it has grown in size but has flattened out. A plastic surgeon told me 1 month ago that it was an atrophic scar and that skin loss was apparent. What does this mean in terms of how this scar is healing? Will it continue growing and if so how can I stop that from happening? for scar management I keep petroleum jelly on it day and night and massage once or twice a day, I use sunscreen when I'm outside.
