I've recived 4 laser sessions (qswitched) on my tattoo wrist ( the tattoo is pretty new, go it las t year). I can see sone fading but im worried sone lines dont seem to be reacting. I'll leave a pic where you can see the parts that have fade and the very black lines. Are this lines likely to react with more sessions? Is the fading I see an okey result for 4 sessions?
