How do you get rid of tattoo keloids?

There is nothing that you the client can or need to do to prevent this from happening. A "keloid" in relation to a tattoo simply means that the artist that did the tattoo simply went to deep and scarred you. Keloids are more common and unpredictable when it comes to body piercing, especially surface piercings. The only way to reduce the appearance of them in that respect is to use diluted Tea Tree Oil. This will not work with a tattoo, as I said, because it is irrevocably scarred.
