Picosecond Tattoo Removal

This Picosecond laser uses advanced PressureWave technology to shatter tattoo ink into tiny particles that your immune system can remove from under your skin naturally over time. This is currently the most advanced laser treatment available for safe and effective tattoo removal.

How does picosecond laser work?

A picosecond is a million times shorter than a second.

This ultrashort pulse generates two effects:

  1. Sudden increase in temperature in the tattoo pigments. The Picosecond pulse set at 500-750 picoseconds produces a highly concentrated energy delivery in a billionth of a second. In this way, the temperature increases very sharply and the pigments explode into tiny particles, which are metabolised by the body more easily.
  2. Effectiveness in smaller ink particles. This type of particle has a shorter thermal relaxation time, so that its elimination was not satisfactory with conventional Q-Switched type lasers.

How do tattoo pigments accumulate on the skin?

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.


  • Have a diameter of between 40 and 100 nm.
  • They can be found in the interior of the cells or in the extracellular space.


  • Are concretions of particles.
  • Typically they have a size between 10 and 400 times larger than the particles with a diameter of between 400 and 4,000 nm.
  • They are found on the intracellular level.

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 Picosecond energy, thereby creating a very intense photomechanic effect.

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.

Advantages of Picosecond

The main advantages of Picosecond laser for tattoo removal are:

  • The treatments are effective with half the energy, which is much gentler on the skin.
  • Lightening of the tattoo is achieved more quickly.
  • Lightening of the tattoo is achieved in half the sessions or less than with the traditional lasers.
  • Can treat recalcitrant tattoos, i.e. tattoos that are very resistant to laser and that after a high number of sessions, there is still a high density of residual pigment.
  • Increases efficiency in removal of light blue or light green pigments.
  • The thermal mechanism of the tattoo removal is greatly improved.
  • The maximum level of mechanical stress is achieved.
treatment frequency

Usually, we recommend a course of 6-12 treatments, to take place every 6-8 weeks for the best in results.
