The Pico Laser uses ultra-short pulses(one trillionth of a second in length)through beehive lens to hit the melanin with a great pressure,which causes the melanin shatters into tiny dust-like particles.Because the particles are so small,they are more readily absorbed and eliminated by the body.meanwhile,the shockwave penetrates deeply into the Dermis layer,which stimulate skin collagen to regenerate, which means better clearance of the melanin and less treatments overall.Therefore,the result of removing pigment and improving skin can be achieved.
