A tattoo is a design or marking made by the insertion of a pigment into punctures or cuts in the skin. In technical terms, tattooing is micro-pigment implantation. Tattoos are a type of body modification. The most common problem that develops with tattoos is the desire to remove them. Removing tattoos and permanent makeup can be very difficult.

Although tattoos may be satisfactory at first, they sometimes fade. Also, if the tattooist injects the pigments too deeply into the skin, the pigments may migrate beyond the original sites, resulting in a blurred appearance.

Tattoo Removal Techniques
Methods for removing tattoos include laser treatments, abrasion, scarification, and surgery. Some people attempt to camouflage an objectionable tattoo with a new one.

Laser treatments can lighten many tattoos, some more easily and effectively than others. Generally, several visits are necessary over a span or weeks or months, and the treatments can be expensive. Some individuals experience hypopigmentation -- a lightening of the natural skin coloring -- in the affected area. Laser treatments also can cause some tattoo pigments to change to a less desirable shade.
Unfortunately, knowing what pigments are in your tattoo or permanent makeup has always been difficult and has become more so as the variety of tattoo inks has multiplied. Inks are often sold by brand name only, not by chemical composition. Because the pigments are sold to tattoo parlors and salons, not on a retail basis to consumers, manufacturers are not required by law to list the ingredients on the labels. Furthermore, because manufacturers may consider the identity and grade of their pigments "proprietary," neither the tattooist nor the customer may be able to obtain this information.

There also have been reports of individuals suffering allergic reactions after laser treatments to remove tattoos, apparently because the laser caused allergenic substances in the tattoo ink to be released into the body.
