Has anybody had the salabrasion done or done it?

Hi! I just had my eyebrows tattooed two days ago, the shape is ok, though she went over my eyebrow line in some places which I really don't like.  Although the shape is ok, I know that even if they fade 35%, they will still look too 'painted on' for my liking.  I really thought that I made it clear that I wanted something very natural looking.  I had one of the lightest colors available, and I am so glad, because she said that she would have done a dark brown on me (I am hispanic, and have medium olive skin).  I feel that I will be happier if I can get at least some of the color out, and I feel that now might be a good time to do that, and have some of the pigment washed out before it sets.  Has anybody had salabrasion? Does it fade tattoos considerably?.....help!
