Laser Picosecond bụ ngwaọrụ laser nke na-eji oge mkpirisi mkpirisi dị mkpụmkpụ iji lekwasịrị anya pigmenti endogenous na ụmụ irighiri ink exogenous (egbu egbu). Ọkpụkpụ ahụ na-adịgasị iche dabere n'ogologo ebili mmiri a na-eji, ma neodymium-doped yttrium aluminum garnet (Nd: YAG) kristal (532 nm ma ọ bụ 1064 nm), ma ọ bụ kristal Alexandrite (755 nm).

The PicoSecond Nd: YAG laser na-enye anyị ohere ịgwọ ụdị anụ ahụ sara mbara yana ọtụtụ agba ink egbugbu. Site na oge ultra-short picosecond pulse, enweghi ahụ erughị ala n'oge ọgwụgwọ yana ọgwụgwọ ngwa ngwa. Laser na-abanye n'ime epidermis n'ime akpụkpọ ahụ ma na-emetụta oke pigmenti ma na-etinye uche ya na pigmenti. Ebe ọ bụ na pulses laser dị mkpụmkpụ na nanosecond wee bịa na ike dị elu, oke pigmenti ahụ ga-aza ngwa ngwa ma gbajie n'ime obere iberibe, nke a ga-ewepụ site na metabolism. N'okwu a, pigmenti na-eji nwayọọ nwayọọ na-adịwanye ọkụ ma mesịa pụọ.
