Abstract
A new picosecond laser (Impulse+, Irisiome, France) with bursts of ultrashort pulses was recently proposed for tattoo removal to enhance efficiency and patient tolerance. This study aims to analyse the optical properties of tissues and cells of the skin subject to laser irradiation with or without black ink pigments. Results show that black tattoo ink alone is not cytotoxic for dermis cells but it can induce particular cells’ reactions up to death with laser irradiation. These results are promising and help understanding picosecond laser process for tattoo removal.
