Tattoo Removal 

The standard modern method is the non-invasive removal of tattoo pigment using Q-switched lasers. Different types of Q-switched lasers are used to target different colors of tattoo ink; depending on the specific light absorption spectra of the tattoo pigments. Typically, black and other darker-colored inks can be removed completely using Q-switched lasers, while lighter colors, such as yellows and greens, are very difficult to remove. Success depends on a wide variety of factors including skin color, ink color, and the depth at which the ink was applied
