Light
is not always a nemesis of skin and beauty. Like everything else on the face of
the earth, light has positive and negative effects on humans and the
environment. Mind you, laser was first imagined to be an adjunct for health and
treatment purposes; however, it was later developed as a weapon. On the other
hand, the computer was originally intended to bolster military intelligence
during the war, but modern science harnessed it for medical applications. It
therefore came to pass that other than an interesting contraption of sci-fi
series like Star Trek, laser is now an indispensable aid in dermatology,
particularly in the increasing popularity of laser hair removal Calgary clinics
- move over Captain Kirk and Mr. Spock.
The
technology behind the amazing procedure is Intense Pulsed Light (IPL). This
safe and non-invasive procedure is grounded on the principle of selective
photothermolysis. Basically, the effect of light on the skin is a function of
the varying extent of absorption of electromagnetic radiation on the skin. The
treatment involves matching a particular wavelength and pulse duration in order
to obtain optimal effect on the target tissue while ensuring minimal effect on
the surrounding tissues. The interaction between the laser and the skin tissue
is a result of the absorption of electromagnetic radiation (the laser beam) and
the accompanying excitation of the photons.
Background
Info
Fundamentally,
laser used to be all in uppercase letters (LASER), which is the acronym for
Light Amplification by Stimulated Emission of Radiation. The credit for the
discovery of laser was given to the American physicist Theodore Maiman. IPL is
situated in the visible light of the electromagnetic spectrum. Once IPL reaches
the skin, part of it is absorbed by the skin, another part is reflected and
scattered, and another part is further transmitted. This is known as selective
photothermolysis.
The
structures on the skin tissue responsible for the absorption of the photons are
called chromosphores. There are various types of chromosphores and the most
commonly found on the skin are hemoglobin and its derivatives such as melanin,
water, and foreign matter in the form of pigmented tattoos. The primary targets
of IPL treatment are melanin and the blood vessels. The fluence or the flux of
radiation delivered within a specific amount of time to the chromoshpores need
to be high enough to destroy them.
Advantages
of Laser Hair Removal
Aside
from the inconvenience of shaving unwanted hair regularly, busy bodies can
benefit from the extra time they can save from not having to shave anymore -
laser hair removal is permanent. Additionally, as long as the treatment is
performed by a professional authorized under applicable legislation in your
locality, it is the safer alternative to shaving. Remember that majority of the
areas where you prefer not to grow hair have more sensitive skin, such as the
underarm and the pubic area. In other words, ridding your body of unwanted hair
is safer than shaving and the procedure is fast, precise, and predictable.
As
a caveat, however, never entrust the procedure to quacks. Laser hair removal
Calgary experts are professionals who offer safe and sanitary treatment options
for unwanted hair in different parts of your body for aesthetic purposes. The
next time you see any unwanted hair on your skin, think about safety first
before aiming that sharp razor - try laser hair removal.
