Ross, I completely agree with you on that point… it does seem like the more removable the tattoo, the less seriously people take their decision to get it and the less thought gets put into what should be a very meaningful decision; it’s as if we’ve lost the whole notion of permanence when it comes to tattoos… Nonetheless, as a biochemist I can’t help but marvel at how tattoos work in general, and especially at how both lasers and new developments such as the ink work to get rid of them. :p
