Cosmetic laser surgery.

The fact that multiple wavelengths of light (and, therefore, different lasers) are needed to treat multicolored tattoos and several laser sessions are required for tattoo eradication in most instances, elimination of tattoos remains an expensive endeavor in terms of money and time. The obvious benefit of lasers in the treatment of tattoos, however, lies in their ability to eliminate tattoos without scarring or dyspigmentation. While no single commercially available laser system currently exists that can treat all tattoos, combination laser systems may make treatment of a wide range of tattoo colors a reality in the near future.
