Laser hair removal has quickly become a popular technique used by both celebrities and the average person. People have discovered just how effective the results from this procedure can be and despite the price they see results that are long lasting. Every clinic or spa that offers this treatment will use various techniques and laser hair removal equipment. It is important to understand each one, how they are different, and what makes them useful or useless.
Alexandrite Laser
This is a long pulse laser that is able to penetrate deep into the dermis of the skin. When it reached this level the heat will begin to build up into the shafts of the hair and disconnect the follicles that are in the active growth stage. The biggest disadvantage of this type of laser is that the results are not as long lasting and people with darker skin are more likely to have negative side effects.
Diode Laser
This is one of the most effective devices. It will trigger a number of small diodes which will in turn create a type of wavelength made up of light. This light will penetrate into the skin and separate the hair follicle to remove the hair. These wavelengths are often so long that they are easier to use on people with darker skin. The one downside is that in rare cases it can cause a severe allergic skin reaction that requires drug therapy to control.
YAG Laser
This type of laser works in the same way as the diode except that it creates two wavelengths instead of just one. One wavelength will work itself deeper into the hair follicles. The other is a green light that will treat the follicles that are near the surface of the skin. This laser makes it easier to use epidermal and surface cooling protection on the skin to prevent any damage.
