During
the past decade, laser technology has advanced to a level of
precision that allows the non-invasive treatment for cosmetically
enhancing procedures as well as serious medical conditions that
in the past either had no effective remedy, or acceptable results
could only be achieved through costly, painful or risky surgery.
To understand how this technology works, it is important to understand
the technology itself, the tools of the trade, and protocols for
their use in treating a wide variety of conditions.
A
laser beam is very specific frequency of light that is monochromatic.
It contains one precise wavelength of light. The wavelength of
light, or frequency, is determined by the amount of energy released.
The light released is also coherent and
directional. It is “organized,” which
means that all of the photons have wave fronts that launch in unison.
This creates a tight beam that is highly concentrated and therefore
able to precisely target a specific point.
When a particular frequency of light is directed at a specific
tissue, it is absorbed by the naturally occurring pigment within
that tissue.
This remarkable process is called ‘selective thermolysis.’ In
pigmented skin lesions, the targeted pigment is melanin, which after
absorbing the laser’s energy will break up and disintegrate
over the course of a few days, or turn into a scab and simply fall
off in 1-3 weeks. In vascular lesions the laser energy is absorbed
by the pigment in the hemoglobin, which instantly collapses and
destroys the unwanted vein. Over the course of a few weeks the
body simply
dissolves and removes any remaining fragments of the destroyed
vein.
