Hi, I used to do cosmetic tattooing years ago. What I have had done is eyeliner, eyebrows & lip liner. A friend of mine had her eyeliner done in Vegas. From what I've learned is that there are a couple of different procedures (my opinion). The procedure that I have learned & had done has lasted years so far (approx. 20 yrs.) & the one she had done faded within 2 yrs., so yours might end up fading. Otherwise it will just change with age (gravity).
Kat Von D makes 2 cosmetic products that are meant specifically for covering tattoos. There is a tattoo concealer for bigger tattoos & a tattoo eraser pencil for smaller tattoo coverage ( I think the pencil would help you for such a small area). I found them both at www.Sephora.com. I have no personal experience with either, but there are reviews on them at the site to help you decide if it's a good product for you. I hope this info will help you. Westyjames.
