A picosecond laser emits optical pulses with extremely short duration of between 1 picosecond and some tens of picoseconds. The nature of picosecond lasers allows for absorption of wave pulses that generate a brief and precise photo-thermal effect within the targeted area – alongside ultra-structural and intrinsic chemical modifications in association with rapid changes involume. This is also called photo-acoustic effect, for the popping sound it creates. By passing these waves through the skin in the area of the tattoo or pigmentation, the laser breaks the ink particles – leading to chemical and structural changes in the skin, thus allowing the particles to fracture, and be disposed by our own body’s lymphatic system..
Pico + Nano
First, the Nanosecond pulses are used to deliver short bursts of energy that break down the larger and deeper pigment or ink particles. Then, the area is rescanned with Picosecond pulses that dismantle the smaller and shallower particles. This combination yields far better results than using either one of the technologies on its own.
High Energy
The high energy levels of PiQo4 allow pigment/tattoo removal with fewer treatments compared with other competing laser systems. They can be set as either Nano or Pico, for dual pulse treatments.
4 Wavelengths
Each pigment color absorbs a specific wavelength – PiQo4 offers 4 wavelengths in order to treat the broadest range of pigment/tattoo colors, on the widest range of skin types. Its four wavelengths – 1064nm, 532nm, 650nm and 585nm – target the most frequently used tattoo colors ranging from light orange to dark black.
