The Pico Laser (or picosecond laser), is a non-ablative laser that is mainly used for pigmentation removal, acne scars, skin rejuvenation and brightening, and tattoo removal.

The Pico Laser works in ultrashort picosecond laser pulses instead of nanosecond pulses in a Q-Switched Laser.

This means that the pulse duration (how much time 1 laser shot stays on the skin) of a Pico Laser is 100x shorter than a Q-Switched Laser, and more laser shots can be fired by a Pico Laser in the same amount of time compared to a Q-Switched Laser.

The shorter pulse duration also means that the skin heats up less and this reduces the risk of hyper-pigmentation which can sometimes form due to laser procedures.
