WTF HAPPENED?

Wtf happened to my tattoo? This isn't my 1st tattoo, this isn't my 1st color tattoo...it was colored with light blue that clearly didn't stick and now it looks like I got vitiligo...how'd the damn ink steal my melanin?. I've never had this kind of reaction before and no known allergies. Can anyone explain this? Once it heals, I'm supposed to go back and have it covered with black & Grey.

Thanks for any input.
