There are a few tattooists who specialize in cosmetic work, but I haven't personally kept a list of such - and don't know what the realistic prospects might be.

In a word no. When your skin color changes over time, it's highly unlikely that the ink will change at the same rate and still be the same tone. You'll just have two different colored spots.
