PiQo4, from Lumenis, is a non-thermal FDA-approved laser for treating multiple types of pigment issues. Its PicoFractional handpiece converts light into sound waves to deliver Pico pulses.
PicoFractional, uses the conversion of light into sound waves to create tiny holes deep within the dermis which is known as Laser Induced Optical Breakdown (LIOB).
The photoacoustic beam creates pressure waves, that initiate an enhanced inflammatory healing response resulting in increased production of collagen and elastin, so that skin regenerates and heals itself naturally and rapidly – a process called ‘neocollagenesis’. All of that without thermal injury.
