Although there has been some good advise here, I would 1) talk with your tattoo artist and 2) do your own web search on tattoo care. I know my artist warns against any antibiotic cremes or oil based lotions, as well as anything that closes off airflow to the art for about 2 weeks. He also warned against prolonged exposure to salt water as salt does have a slight bleaching affect. I was to get a new tat a couple weeks before a week long dive trip to Little Cayman and was strongly advised against it. All this said, the biggest culprit to a fading tattoo is sun. I use SPF 50 on all my tats while they are exposed.
