Various types of lasers are used for tattoo removal. The breakthrough to picosecond technology has been achieved through constant further development and research in the laser industry. Picosecond lasers, as the name suggests, work in picoseconds. This means that much shorter energy pulses are emitted than with other laser systems. Energy pulses in the 300 to 450 ps range produce faster and more effective results as the color pigments are broken down into much smaller parts.
