Pictures of laser hair removal
In recent years, against a background of extremely high popularity of laser hair removal, there was quite a number of systems for the so-called photo epilation. The basis of how laser hair removal, hair removal and put one and the same physical principle selective heating of the tissue due to absorption of light energy (in the case of all body hair laser hair removal containing melanin).
By the way, this is why advertising statements about the possibility of using hair removal to remove the light, and even more gray hair does not correspond to reality - blonde hair contain very little melanin.
As is known distinguishing feature is its laser monochrome ie each specific type of laser emits light of a strictly fixed wavelength laser energy and all fall on the same wavelength. Ie using laser medicine, knowing the physical properties of the lasers of a particular type, we can say with 100% certainty to predict in advance how laser radiation would affect the fabric (in the case for epilation of hair without damaging the skin). Based on this, for use in a particular field of medicine select appropriate types of lasers.

Hair removal systems, as a cheap replacement laser, using so-called krypton lamps, whose characteristics can be, very roughly, compared with lamps that are used in the flash. The range of light waves emitted by a lamp is in a very wide range from extremely dangerous to human ultraviolet to infrared.
Manufacturers of hair removal systems are forced to put-off filters are extremely dangerous to humans ultraviolet (such a filter, in the simplest case, can serve as ordinary glass). The remaining part of the spectrum (wavelengths from 600 to 1200 nm) are trying to get to "work" for the purpose of hair removal.
In order to somehow get closer to the impact of the efficiency of the laser, producers set, passing them off as the latest achievements of guaranteeing supposedly phenomenal efficiency, various additional light filters, which are designed to focus all the energy lamps in a fairly narrow range.
However, there are filters that can be at least as something to bring the properties of light normal, albeit a very powerful lamp to the physical properties of the laser - pulse energy lamp - the flash is "stretched" on a wide range of wavelengths. Part of this energy actually absorbed by melanin and leads to heating of body hair.
Since the so-called "Energy peaks" for virtually all hair removal systems are in the range in which the human skin is also quite good at absorbing light (600-750 nm) part of the energy spent on a potentially dangerous heating of the skin, instead of what would, in the case of laser hair removal, go for heating the body hair and increase thus the efficiency of hair removal.
It is known that laser hair removal hair removal systems for non-compliance with conditions of allotment of excess heat from the skin will inevitably lead to a rather severe skin burns, and in the most critical cases, scar tissue.
