Conch Piercing Scars ๐Ÿ‘Ž๐Ÿพ

Ol

Hey! So recently I discovered I have a hefty hypertonic scar on the back of my ear from my piercing. I figure it is due to the metal because I have problems with that in the past. I was wondering if it would be an issue to put in a smaller gauge sterling sliver stud (such as one for an earlobe) for the time being as the scar fade away? Would the piercing hole become closed or change? (Iโ€™ve had the piercing since the middle of October, 2018.)
