The term laser is an acronym for Light Amplification by Stimulated Emission of Radiation, i.e. light amplified by stimulated emission of radiation.The developed the first laser was in 1959

using a Ruby Crystal to produce a red light with a wavelength of 694 nanometers (nm).

Laser consists of a resonator containing an average asset able to emit stimulated radiation. The average asset is contained within the optical cavity laser. At the end of the resonator is parallel

mirrors; an energizing bomb is the source of thermal, electrical or optical, energy that is then absorbed by the average asset. The average asset (alejandrita, diode, ruby, neodymium yag..)

tends to give name to the laser.

Laser hair removal is a method of hair removal that has existed only recently, it was in 1958 when it was discovered the laser, and shortly after in 1994 developed the Ruby Laser of high

power that was used to remove the hair, although at the beginning it could only be used in very clear skins because of the danger of producing any burnwith the passage of time and thanks

to technological advances, its use has been very effective in the treatment of hair removal, providing long-lasting and safe results.

For wax laser radiation must deposit their energy in the area white (melanin). Of the radiation that reaches the skin, some is reflected and elsewhere penetrates through the skin absorbing it,

releasing heat and thereby destroying the hair matrix cells.

Melanin is distributed in follicular structure, especially in the follicle stem to a lesser extent in the dermal papilla and the bulge being the destruction of the same routes. For both, the largest

concentration of melanin, more likely to destroy the hair follicle.

Laser hair removal has generated considerable enthusiasm for its effectiveness. The shutter release potential of selective fototermólisis is the melanin in the hair follicle.

Initially the Ruby Laser use for hair removal. Currently, laser Alejandrita GentleLASE and GentleYAG ND: YAG for Candela and the Lightsheer diode laser have exceeded his predecessors in

efficacy and safety; These include a cooling system that reduces the adverse effects such as damage to the epidermis.

The laser energy on the hair an effect fototérmico to generate a temperature sufficiently high to produce irreversible damage to follicular structures.

Lasers are classified in high-power and low-power.

History of the laser: For permanent hair removal treatments.

Each medical, or cosmetic procedures has a history which helped to progress and improve the treatment or procedure to what is today. .The story of this hair removal procedure does not

have a direct impact in the treatment of hair removal, but in any case it is interesting to know it.

In the early 1960s lasers began to be popular in many fields product. Around that time, many medical professionals began to think of using lasers as a working tool in hair removal. When it

developed the first laser hair removal, it was used for a long time as experimental procedure, not he was exposed to the public during this time.

Some of the first lasers were not effective for hair removal. These lasers were modified and this is how laser hair removal was possible. With those early lasers occurred some painful

associated effects. These associated effects included blisters, redness of the skin and inflammation. Didn’t take much time to appear a new generation of lasers which reduced or eliminated

completely a large number of these associated effects.

In 1995 was the year in which developed the first laser hair removal approved by the FDA. This interesting new product was marketed under the name of SoftLIght. SoftLight was one of the

first lasers available for public use.

Unfortunately, the procedure did not reach the popularity which was believed or originally planned. The FDA tried to promote it but it was too late for many patients.

The manufacturer of the SoftLight and hair removal with laser treatment centres using such a system announced that the procedure was of permanent hair removal. A large number of

patients reported recurrence in the growth of the hair not long after the alleged treatment of permanent hair removal.

Due to the marketing of the Softlight as permanent hair removal laser, produced a large number of demands. In many cases, patients were financially rewarded for its not definitive treatment

of hair removal with laser.

Every day there are new technological advances. These advances are those who changed the development of lasers used to remove unwanted body hair.

At this time with laser hair removal is a popular procedure that offers some or no side effects. With the number of engineers and scientists working constantly in the way of improving

equipment laser, it seems that laser hair removal will continue to progress and increasing its popularity.

Although the history of laser hair removal is something many patients do not think, in fact he is as interesting as the procedure itself. It is easy to see that science and technology helped in

the development and improvement of the laser for hair removal.

It is possible that, without science, engineering and technology, epilation lasers could be as successful or popular as they are today. The next time you think of laser hair removal or you’re

sitting in the consultation of the doctor waiting your turn, remember that the history of the procedure is what makes it the laser hair removal is safe and effective for
