808nm diode laser permanent painless hair removal machine pico nd yag tattoo removal device triple wavelength 2 handles q-switched, Black

the principle :(semiconductor) diode laser hair removal is a non-invasive modern hair removal technology, which can destroy hair follicle structure and permanently remove hair without scalding the skin laser tattoo equipment adopts the q switch mode, there is an adjustable infrared button on the handle.you can adjust the infrared focal length flexibly,which makes treatment more accurate. which makes use of the instantaneous emitted laser to break the pigment in ill structure. that`s the laser instantaneous emit theory: centralized high energy emit suddenly, which makes laser of settled wave band in-stantaneously penetrate through cuticle to the ill structure in 6ns, and break the relevant pigments quickly. after absorb the heat, the pigments swell and break down,.syi
