Fading with Saline
Some tattoo artists can fade a tattoo by “tattooing” (not injecting) saline solution into the area where the old ink resides. This is most effective with older tattoos, and is not a reliable method for tattoo removal. However, sometimes this can be done to fade a tattoo and make it easier to cover it up with a new tattoo. There is some controversy among tattoo artists as to the effectiveness of this technique, but it poses no harm to the client and is worth a try for someone wanting to lighten an existing tattoo. Finding an artist that does this, however, may be difficult.

This is from http://patient-info.com/tattoo.htm There are many options mentioned on this site ... Salabrasion seems possible.

Salabrasion

Salabrasion, a procedure which is centuries old, is a method still sometimes used today to remove tattoos. As with the other methods, a local anesthetic is used on and around the tattooed area after which a solution of ordinary tap water dipped in table salt is applied. An abrading apparatus such as the one used with dermabrasion, or an even simpler device such as a wooden block wrapped in gauze, is used to vigorously abrade the area. When the area becomes deep red in color, a dressing is applied.


Sunlight can also fade a tattoo over time.

I hope this helps you.
