A question about white tattoo ink?

I have heard a lot of negative stuff, hearsay, about white ink tattoos. I don’t personally know anyone with a white ink tattoo to ask, so I’ll turn to Fluther.

If you have a tattoo with white ink would you tell me about it, please? How has it lasted over time? Have you had it for a year? Five years? Ten or more? Does it ever need refreshing?

If someone close to you has one, I’d appreciate hearing about that, as well.
I am looking for personal accounts, here.

Thanks
