Changed Review from Fair to Good
I have brown skin and after 12 hours I did not see anything.  The tattoo appeared clear on my skin.  After three days, no joke, the tattoo turned from clear to black.  I did get a tattoo after three days, but I wanted something right away for a photoshoot.  So I had to purchase another product for the tattoos.  I am returning the product because I can't use them anymore.
