Reply to comment by YoungPatrickBateman in I'm John Swierk, assistant professor of Chemistry at Binghamton University, State University of New York. My team and I are working to understand the molecular composition of tattoo inks to provide a broader understanding to artists and consumers. AMA! by intengineering

I'm also fair skinned and grew up surfing with fairly diligent sunscreen use but have definitely had more than a few days of sunburn from lack of reapplying. I have a black piece on my upper arm and one on my upper thigh. My thigh almost never sees sunlight and both those 20 year old tattoos have the same level of color degradation.

Interesting. I wonder how much a persons personal biology plays into the degradation of ink in conjunction with external environmental factors.
