InfinitInk is a tattoo ink, which allows for easier tattoo removal, with removal up to three times faster than conventional inks. It is produced by Freedom2, Inc., and is available as of 2009 in limited release in the United States. It is currently only available in black and red, with other colors planned. The initial ink formulation consisted of inert plastic beads, containing bioremovable dyes. Laser application ruptures the beads, allowing the ink to leak out and be removed by the body.
The concept for this ink arose initially from potential medical uses, such as in reconstructive surgery and in radiation oncology. However, it was clear that a permanent and safe, yet more removable ink would also find use by some artists for decorative tattooing.
