Black tattoos can be removed by Q-switched laser or picosecond laser. Laser acts on melanin through selective photothermal principle, which can instantly crush it and metabolize it, thus achieving the effect of tattoo removal. However, it cannot be completely removed after one treatment, and usually needs 3-4 cleanings. Color tattoos are mixed with various pigments, which may be green, yellow, red, gray and so on. At present, there is no laser equipment that can aim at multiple colors.

Therefore, the removal effect of color tattoos is not good. It is suggested that you should think twice before tattooing, so as not to affect your future work and life.
