Alexandrite laser and other apparatus used in hair removal. Practical comparison. Part I / Photo epilation
Each of us in life faced many times
with the problem of choice.
In addition, as a rule, the greater
variety of choices, the heavier to make the right decision.
Such high demand in our time, as the
procedure of laser hair removal, is not exception.
In spring appeared a huge number of
advertisements and offers of beauty and health centers of different
levels to get rid of unwanted hair.
But few of us have the perception that
signing up for "a laser hair removal" we not always and not
everywhere could find the same procedure ...
The procedure of "laser hair
removal” in various beauty salons is held by different devices and
different procedures (level of training requires another discussion
Different methods of hair removal
determine differences in the ultimate efficacy, safety procedures,
and also differ significantly in preparing for the procedure.
To understand the various techniques of
hair removal, and to understand why, in author’s opinion, it is
specialized Alexandrite Laser hair removal the most effective and
safe. This article is about it.
Consider the currently used methods of
hair removal in comparison with the "Gold Standard Hair Removal
-Alexandrite laser device ":
1. Photo epilation
Despite the fact that photo epilation
as a technique appeared relatively recently - it is not effective for
the permanent long-term hair removal, in comparison to all currently
existing methods of laser epilating.
Why so, you ask?
It's simple. Apparatus for hair removal
cannot develop necessary for good damage hair follicle power.
The strength of light energy acting on
the follicle during hair removal in tens or hundreds times is smaller
than the effect of any laser device.
And once again the main reason for this
is that the action of photo epilator based on the use of broadband
(relative to laser beam), pulsed lamps as light sources.
A wide range of wavelengths of photo
epilator’s light is from 500 nm to 1200 nm partially narrowed by a
filter, which cuts off part of the "unnecessary" of the
spectrum, since the effective impact on the melanin requires only one
wavelength sufficient power (as in laser systems). But as a result of
narrowing the spectrum of light filters, there is huge decrease of
energy of the light beam in exit (on the skin surface).
What can make the operator conducting
procedure to "improve the efficiency of procedure" in the
fall of power output?
That's right – to increase the
capacity of incoming energy flash lamp at the entrance!
But with increasing lamp the power
capacity of a wide range of wavelengths also increase. And as a
result on the patient's skin at the output "works" too wide
range of light waves (a set of different wavelengths), which not only
heats melanin pigment in the hair follicle, but also other structural
components of the skin (hemoglobin blood cells, water connective
This, in turn, leads to uncontrolled
and unpredictable overheating skin, pronounced pain, hyper- and
hypopigmentation with the risk of burns.
Maybe you have a question - is it
possible to construct such a filter for hair removal, that the
spectrum photo epilator became narrow "like a laser”?
The answer is no.
The reason – the laws of physics. For
example, to narrow the range of 10 times, the filter must absorb
about 90% of energy outbreak.
To make the range "like a laser"
in only one wavelength, the spectrum of flash lamp should be narrowed
down thousands of times!
But in this case the main target
(unwanted hair) "will include" only a paltry fraction of a
percent of energy outbreak. And the meaning of the procedure will be
lost in principle ...
How do you think you will choose an
operator that makes hair removal procedure: low power and multiple
visits procedures (of course with their payment), or high power and
burns with the proceedings client?
In my opinion the answer is obvious. As
the result the need for a large number of sessions - up to 20-30
Abroad photo epilators called "lasers
for the poor." They invented by manufacturers as an alternative
expensive laser facilities, to increase the availability of
procedures and reducing the cost of the acquisition. Photo epilators
much simpler in design and are not comparable to achieved result with
The cost of such apparatus, and
accordingly, the procedure is a lot cheaper. Yes, and the customer
service of "photo epilation" understands that value defines
less efficient (read more distant) result.
However, in Ukraine, the cost of hair
removal procedure is almost equal to the cost of laser hair
The design of alexandrite laser device
allows you to emphasize only one! wavelength (maximum selectively and
safely absorbed by melanin) at 755 nm, also it convey a sufficient
amount of energy with this length wave (no more, no less) in germ
band hair follicle to heat and destruction (irreversible and 100%
Thus a wavelength, in contrast to the
pulse of broadband light sources IPL (photoepilators) selectively
(i.e., selectively) is absorbed by only one target - melanin - the
pigment-protein, which is in the hair shaft and its germ band. And it
is absolutely safe for vessels, connective tissue and skin cells.
