No, but black ink removes the best. Red, orange, pink, and warmer colors respond well. Purple and yellow are variable but usually removes well. Now (since May 2008) we are able to more successfully remove green and teal blue ink. White, flesh tones, and permanent make-up can turn darker with laser and must be tested before treatment. * As we always work hard to earn loyalty – if you had this service “before” 2009, and did not get full results; you are welcome to come in for a complimentary treatment to make a further educated decision. Some white ink may not be detected by the laser (but check back often for any updates).
