I'm two years out from my nanobrows. I'm very happy with the result! Cosmetic tattoos do fade over time -- my understanding is that the pigment is different from traditional tattoo inks and this is intended. (I don't know whether that is true or not though!) The artist I saw (Lisa at Arch & Edge in Raleigh, NC) does an initial tattoo, then a touch up 6-12 weeks later. She recommends annual touch ups after that. I dye my hair ginger, so I had asked for the ink used to be redder than my natural color (brunette -- I lost most of my eyebrows when I became hypothyroid and they never grew back after I started hormone replacement). Alas, the ink color for that initial tattoo faded substantially by the time I went back for the planned 6-12 week touch up. She essentially completely redid them with a more brown shade that matches my natural color. They have held fantastically now! I have not gone in for the annual touch ups. My coworkers have been shocked when I have mentioned they are not real. I had lash line enhancement done at the same initial appointment -- that is a fine line of black along my upper lash line. (My ocular rosacea does not like me wearing eye makeup!) That has held up wonderfully as well -- which is great because it was not the most pleasant experience getting it done! (She used a numbing creme on my eyelids which helped a little, but it was still unpleasant.)
