Stop doing Pico Laser on Melasma! | the Ogee clinic
Q-switched nano-second laser machines generate laser energy with pulse widths at the nano-seconds range, that is one billionth of a second (1..0 ns =10 −9 s).. To put things into perspective, 1 nano-second = 0..000000001 seconds.. Recently, a new wave of laser technology, pico-second lasers, have become commercially available..
