Thinking about getting tattoos. TW: self harm

I really want to get a tattoo on my forearm because I’ve never keloid there. I have keloids on my face, chest, and back.

I’m just scared this will cause me to keloid. However, A LONG TIME AGO, after my other keloid developed, I used to self harm on my arm. It was pretty superficial, and the scares eventually fade, but I never got a keloid. Do you think I’ll be safe to get a tattoo?
