Saline pigment lightening is one of the safest methods of removing ink from the skin. It happens in a very similar way to your original procedure. A hypertonic saline solution is implanted into your skin with tattoo needles. As your skin heals, the ink is released and pushes out through the healing process. Nothing but surgery can immediately remove all pigment in the skin, however, saline removal can effectively lighten, and in many cases remove all visible traces of ink in the skin, allowing for a new procedure to be done on top, or the skin can be left clean.
