While tattoos were once considered permanent, it is now possible to remove them with treatments, fully or partially. Tattoo removal is most commonly performed using lasers that react with the ink in the tattoo and break it down. Laser removal of tattoos requires repeated visits. During the treatment process the Laser light passes harmlessly through the skin targeting only the ink resting in a liquid state within. It is very common on all tattoos to experience blistering on the first one or two treatments with any wave length, this is normal and expected. The time duration (pulse duration) of the laser energy must be very short, so that the tattoo pigment is heated to fragmentation temperature before its heat can dissipate to the surrounding skin. Otherwise, heating of the surrounding tissue can cause burns or scars. Different lasers are better for different tattoo colors. Consequently, multi-color tattoo removal almost always requires the use of two or more laser wavelengths. Complete laser tattoo removal method requires multiple treatment sessions, typically spaced at least eight weeks apart. The amount of time required for the removal of a tattoo and the success of the removal varies with each individual.
After the laser tattoo removal, about half of the patients will show some transient changes in the normal skin pigmentation. These changes usually resolve in 6 to 12 months.
