Genetics or Badluck

So i got my earlobes pierced for a second time 4 years ago. 2 years after i got them they developed into a keloid that i recently got removed. The thing is the whole 2 years i had them they did not heal and were constantly irritated. However, i still want pierce either my lip or my nose but i don’t want to repeat what happened. So should i risk it or not ?

PSA, I don’t have a history of keloids neither does my family

i got a regular silver barbell and kept that for a couple months before switching it to another barbell idk what material any of them were made of. For aftercare i mostly just used salt and warm water. They were sore most of the time even without them getting tugged on or touched.
