Decorative tattoos have a history dating back at least 5000 years. The desire to remove them has probably existed for just as long. Early attempts at tattoo removal have had less than desirable results. Dermabrasion, salabrasion and Argon or C02 lasers have left behind scars in place of the tattoo. The advent of Q switched pulsed lasers has made tattoo removal a far more effective procedure, permitting the removal of most tattoo inks with a very low risk of scarring. The Medlite Q switched Nd:YAG laser is the newest system in this class of lasers. The Q switched pulsed laser can significantly lighten or remove many tattoo inks. It is particularly advanced in the removal of blue, black and red inks. The Q switched pulsed laser removes tattoo ink with the energy of light. Just as natural sunlight is made up of light wavelengths of many colours, a laser is designed to produce one or more specific wavelengths of light. These wavelengths are either absorbed, reflected or simply passed through objects.
