Laser Removal Technology For Unwanted
Hair
Laser removal is the latest technology in
removing unwanted hairs in the body. Laser removal works by
transmitting a ray of laser to a collection of hair follicles with
enough control to permanently obliterate the root but safe enough
to the surrounding skin. The process of destroying the root of the
hair is called selective photothermolysis.
This process is called selective because it does
not hit the skin, it only targets the hair. Photothermolysis comes
from the scientific name “Photo” meaning light and “thermolysis”
meaning destroying using heat. To be sure that the surrounding skin
is safe, the skin is cooled using gels, spray or other cooling
agents approved for safe use.
Laser removal works by targeting the “melanin”,
a substance that gives dark color to the hair and the skin. The
perfect person for hair removal should have dark hair and light
skin. Laser removal will not work on people with hair that is
colored red, gray, white or blonde. The hot beam of laser will
focus on the melanin of the skin, people with suntanned skins or
dark colored skins will be at more risks of pigment discoloration
and other side effects.
Laser removal is different from electrolysis.
The process of electrolysis is done by removing hairs one at a time
by sending electric currents to the hair follicle. This is the new
method of destroying groups of hair follicles in one sending of
electric current.
Laser destroys hair only when it is on the
“anagen” phase or growth phase. The anagen phase lasts for a number
of years and approximately 80 percent of body hair is in that
phase. The good thing is that during this phase the hair has plenty
of melanin, which absorbs the light emitted by the laser and is the
target of the whole process.
There are four types of laser beams that are used
for laser removal.
They are the following:
-
Alexandrite
-
Ruby
-
Diode
-
ND and LP ND
Yag
The types of laser light that are used today are guaranteed safe,
easy, effective and convenient.
However, there are some factors that a laser
technician carefully considers to ensure a safe and effective
treatment.
These are the following:
-
Pulse length – considered the
safest for its long-pulsed lasers
-
Fluence – the energy-levels
can be varied for different types of skin
-
Delay – laser light intervals
that lets the hair follicles to cool off during
treatment
-
Spot size – speed of the
laser light the penetrates the hair follicles it also detects the
depth of the root of the hair follicles that needs to be
destroyed
-
Cooling – the surrounding
skin should he cooled using a gel, spray of other cooling agents to
protect the skin from the heat of the laser light
The above information is helpful for people who
would like to permanently remove unwanted hair using laser removal.
It is also best to consult a specialist before undergoing hair
laser removal for safety.
