Can you get scar removal for navel piercings

Nat

I had my belly button pierced around four months ago and long story short it didn’t work out it wouldn’t heal and it rejected. This is my belly after a couple of weeks after taking it out. I’m going on holiday soon and I’m not the most body confident person anyway and wanted to know if you could have micro needling or some sort of scar removal

Here’s how it’s looking now , it’s shiny coz I have treatment on it.
