Picosure® is a laser based on picosecond technology that achieves tattoo removal in a safer, more efficient way in less time.
The demand for elimination of tattoos has increased in recent years, as it is a fashion and a high rate of the population has tattoos. Professional and personal reasons are the most frequent causes for which patients want to remove tattoos.
The incorporation of Picosure® laser to IML's technical equipment is an important step in the removal of our patients tattoos.

The main feature of Picosure® is that it is the first laser for medical applications which emits pulses in picoseconds. A picosecond is a million times shorter than a second.
This ultrashort pulse generates two effects:
To understand the advance of the picosecond laser it is interesting to know how pigments accumulate in the skin when the patient has a tattoo.
The pigments accumulated in the skin in the form of particles and granules.

The thermal relaxation time of the particles is different from that of the granules. The smaller the size of the pigment, the shorter the thermal relaxation time. So we need to deliver energy in pulses shorter than the thermal relaxation time to cause bursting of the pigment.
The pigment particles have a thermal relaxation time of 40 to 1,000 picoseconds. Unlike Q-Switched lasers, that generally deliver in 5 nanoseconds or 50 nanoseconds as pulse width, Picosure® emits at 750 picoseconds. That is to say, the use of picosecond lasers, with a duration 100 times shorter than Q-Switched lasers, improves efficiency when the target of the laser is composed of small particles.
The peak tensional stress is the maximum voltage that a material can withstand while under pressure before rupturing or exploding. This peak is reached by the pigment particles and granules when they are impacted by Picosure® energy, thereby creating a very intense photomechanic effect.
This picture explains the peak tensional stress: maximum pressure that a substance or material supports prior to rupturing or exploding
When the laser energy delivery to the tattoo pigments is done in a time of 705 picoseconds, pigments reach their fracture index more effectively, breaking up into tiny particles that the lymph capillaries can transport for elimination.
At IML, the different types of Q-Switched laser remain important in the various stages of tattoo removal and, in some cases, we apply treatment by combining different devices, depending on the residual pigment, depth, colour and the anatomical region of the tattoo.
At IML we have all types of lasers for tattoo removal
