I Got My Ears Pierced About 7 Weeks Ago With

I got my ears pierced about 7 weeks ago with a gun and since I have been researching and have found out that piercing guns are bad for your ears. I was just wondering if that damage and trauma that was caused by the gun can repair itself if I let the hole close up? And if I take my studs out now will a keloid form? Can keloids form even after your piercing is closed anytime? btw I'm 15% Iberian peninsular, 20% Native American, 55% European my mum is Latino
