Tattoo removal involves the utilisation of various laser technologies, each offering its unique advantages and limitations. The Q-switched laser stands as the most widely employed method for this purpose. This laser excels at precisely targeting tattoo ink particles without causing harm to the surrounding skin. Q-switched lasers are available in a range of wavelengths, chosen based on the specific colour of the tattoo ink. For example, the 1064nm wavelength is effective for erasing black and dark blue inks, while the 532nm wavelength eliminates red, orange, and yellow inks.
