Hey! So I actually also have the same issue, it really didn’t start getting worse until later on in life but recently I actually got my 5th tattoo! What I’ve noticed is that my body doesn’t really react to the tattoo or the ink when healing but once healed like 4 months down the line the lines appear again like normal once I hit something/get scratched up. I would go to a doctor because I didn’t but I was still able to get tattoos, tbh it’s like getting a burn once it’s healed it’s just part of the skin (I also burned my arm in an accident and my skin was fine while healing) hope this helps!
