How does the body remove the shattered ink?
As with any other time the body senses out of the ordinary influences or substances, an immune response will occur. With tattoo removal this takes the form of some swelling and redness in the treated area. In your blood are phagocytes that will carry away the shattered ink particles away and fade your tattoo. Over a number of sessions your body will remove more and more ink until your tattoo is completely gone.
