1. Treatment principle
The PicoSecond Laser uses ultra-short pulses (one trillionth of a second in length) to hit the melanin with a great pressure, the melanin shatters into tiny dust-like particles. Because the particles are so small, they are more readily absorbed and eliminated by the body. This can mean better clearance of the melanin and less treatments overall. PicoSecond Laser is a quick and easy non-surgical, non-invasive laser skin treatment for the body including chest or decollete, face, hands, legs, and more.
2. Picosecond laser VS Q-switch
At Picosecond laser pulse width, the generated photomechanical stress target pigment particle, making its volume expansion instantaneously and resulting in breakup of target into micro-particles, which is much easier for phagocytes to clear. Q-switch laser has pulse width of 5ns or more, its photomechanical stress is not efficient compared to picosecond laser, it creates large particles, and with long pulse width, scattering energy goes toward surrounding tissue, resulting in risks of thermal damage.
Therefore, Picosecond laser provide a more effective and more safe treatment than Q-switch laser
