Actual (reported)The investigators developed an ultra-speed picosecond laser (20ps) with a 20gHz repetition rate that provide very promising results in vitro and in ex vivo skin to remove skin tattoos. The aim of this study is to evaluate the efficacy and tolerance of a new ultra-speed picosecond laser and to compare it to a nanosecond laser for treating black tattoos. In a first phase of the study 10 patients with black tattoos will be treated with increasing fluencies of the picosecond laser to the optimal parameters in terms of efficacy and tolerance. In a second phase, 10 additional subjects with black tattoos will be treated after central randomization on half of the tattoo with the picosecond laser (with the parameters determined in the first phase) and the other half treated with a nanosecond laser.
