Hi all. I am removing tattoo that is black with details in red and yellow and have been through 3 sessions by now. The first two I used a q-switched spectra (I think that was the name) and saw a decent fading. On the last session however, I decided to try the picosure, as everybody says lots of wonderful things about it. The tecnician did warn me that picosure was not good for red and yellow ink, and in fact I didn't any results on these parts. Actually, they seem to have gotten even brighter (!). So, my question is: do you guys know which is the best laser and the best frequency to remove these colors? Looking forward to hearing your advice. Thanks!
