[Picosecond technology speed times 9 times faster than the average nano laser, 90 times faster than Alexandria laser].
Use special optical lens focus 20 times the energy generation [picosecond speed light shock wave].
Stimulate collagen hyperplasia, to improve the skin pores and other uneven puzzle.
Picosecond mechanical light laser use of very short pulse output, the use of optical mechanical shock wave to replace the heat effect, the target crushed into the smallest particles, and the side effects of photothermal effect to a minimum, you can almost solve the purpose of all kinds of pigment spots.
