@oboogie nailed it. That's a solid F***ing tattoo and you should be proud to wear it, microscopic "imperfections" and all.
edit: The older I get, the more I appreciate the Japanese (very appropriate here) concept of wabi sabi, or beauty in imperfections. These are the parts of the tattoo that really tell a story: of past, present, and the human(s) involved along the way. Hopefully you too can see the beauty in that some day, but for now just leave it alone! You're much more likely to do more harm than good.
