Can you get your keloid covered with a tattoo?

A keloid meaning that litle bead of scar tissue you get when a piercing is taken out and heals slightly improperly? you may be able to hide it, but the bump will only go away with sugery, or a dermal punch (a type of piercing that basically uses the piercing equivalent of a hole punch, to literally 'punck out' your skin, and put a piercing in there.

it depends on the age of the scar and if it's flat like at the same level as the skin.

if it is you can tattoo over it, the tattooist will just have to go over it a couple of times so the colour comes out as bright as the rest. but if it's old and flat enough it will only need to be done once.
