Tattoo Removal

Laser tattoo removal usually refers to those non-invasive removal of tattoo pigments using Q-switched Nd:YAG (neodymium-doped yttrium aluminium garnet). Typically, black and darker-colored inks can be removed more completely.

Why tattoo removal ?

In various surveys conducted world wide, people give different reasons to remove tattoo..i.e.

  • They were too young at that time.
  • Just don't want it as its marked for life.
  • A name is written in a friendship which is no more.
  • My parents got it on me.
  • Unwanted for some jobes.

Laser Tattoo Removal

Tattoo removal is done by lasers that can break down the ink particles in the tattoo. The broken-down ink is then absorbed by the body,

A tattoo laser must be capable of emitting adequate energy within the given absorption spectrum of the pigment to provide an effective breakage of tattoo pigment. There are other coloured tattoo such as yellows, greens and fluorescent inks are more challenging to treat than darker blacks and blues, because they have absorption spectra that fall outside the emission spectra available in the tattoo removal laser. Recent pastel coloured inks contain high concentrations of titanium dioxide which is highly reflective. Consequently, such inks are difficult to remove.

Mechanism of action

Generally tattoos consist of thousands of particles of tattoo pigment suspended in the skin.Tattoo pigment particles are permanent because they are too big to be removed. Laser treatment causes tattoo pigment particles to heat up and fragment into smaller pieces. These smaller pieces are then removed by normal body processes.

Laser tattoo removal is a successful application of the theory of selective photothermolysis (SPTL).

However, unlike treatments for blood vessels or hair the mechanism required to shatter tattoo particles uses the photomechanical effect. In this situation the energy is absorbed by the ink particles in a very short time, typically nanoseconds. The surface temperature of the ink particles can rise to thousands of degrees but this energy profile rapidly collapses into a shock wave. This shock wave then propagates throughout the local tissue (the dermis) causing brittle structures to fragment. Hence tissues are largely unaffected since they simply vibrate as the shock wave passes. For laser tattoo removal the selective destruction of tattoo pigments depends on four factors:

  • The color of the light must penetrate sufficiently deep into the skin to reach the tattoo pigment.
  • The color of the laser light must be more highly absorbed by the tattoo pigment than the surrounding skin,like red light is highly absorbed by green tattoo pigments.
  • The time duration (pulse duration) of the laser energy must be very short, so that the tattoo pigment is heated to fragmentation temperature before its heat can dissipate to the surrounding skin. this duration should be on the order of nanoseconds.
  • Sufficient energy must be delivered during each laser pulse to heat the pigment to fragmentation. If the energy is too low, pigment will not fragment and no removal will take place.

Although they occur infrequently, mucosal tattoos can be successfully treated with Q-switched lasers as well.

Complete laser tattoo removal requires numerous treatment sessions, typically spaced at least four weeks apart. At each session, some but not all of the tattoo pigment particles are effectively fragmented, and the body removes the smallest fragments over the course of several weeks. The result is that the tattoo is lightened over time. Remaining large particles of tattoo pigment are then targeted at subsequent treatment sessions, causing further lightening. The number of sessions and spacing between treatments depends on various parameters, including the area of the body treated and skin color.

A predictive scale, the "Kirby-Desai Scale", was developed by Dr. Will Kirby and Dr. Alpesh Desai, dermatologists with specialization in tattoo removal techniques is present to to assess the potential success and number of treatments necessary for laser tattoo removal, Certain colors have proved more difficult to remove than others. For example the molecular size of the green ink particles being significantly smaller than black colour.

R20 method

A new technique using two to four passes with the laser, twenty minutes apart, caused more breaking up of the ink than the conventional method.
