Laser hair removal is one of the most effective procedures of its kind. However, it should be noted that the effectiveness and results of laser hair removal largely depend on the correct choice of laser hair removal machine. Therefore, today Estet-portal will describe the types of lasers that are used in laser hair removal devices, as well as talk about their features and recommended applications in order to achieve maximum results after removing unwanted hair.
If you follow the latest in modern cosmetology, you probably asked yourself what laser hair removal is. This is one of the most profitable areas in hardware cosmetology: there is a constant demand for it, and the cost of procedures is such that it allows you to achieve a payback for the device in a matter of months. Further, the device works exclusively for the clinic.
Features of laser hair removal as a hair removal procedure
The essence of laser hair removal is the selective absorption of laser radiation energy by melanin contained in the hair follicle. This process is accompanied by heating of the follicle and the death of cells responsible for hair growth.
Epilation of one area requires several treatments to finally get rid of unwanted hair. The number of repetitions depends on the efficiency of the laser device, on the ability to adjust its power during the epilation process in order to select the mode that is most suitable in each case.
Laser hair removal is a rather painful procedure, so laser hair removal machines are equipped with special modules that provide cooling to the underlying skin. Most often these are contact cooling plates or air-cooled devices.
A very important parameter when choosing a laser for hair removal is for which Fitzpatrick skin phototypes it can be used. According to this classification, six skin phototypes are distinguished, differing in the saturation of the epidermis with melanin. The wider the possibilities of the laser in this direction, the more versatile it is and can be used both in fair-skinned people with blond / dark hair, and in dark-skinned people.
Types of lasers in epilation devices
The following types of laser hair removal are currently used at the heart of laser hair removal devices, depending on the type of laser: alexandrite, neodymium (Nd:YAG), diode.
Alexandrite laser hair removal is the most painful, which, combined with its limited use on different skin phototypes, causes it to be gradually replaced by other types of lasers. A number of studies show its effectiveness only for phototypes I-III.
The neodymium laser was developed specifically for IV-VI skin phototypes. Its use is also quite painful and requires reliable hardware anesthesia.
The diode laser is the most versatile and can be used on individuals with skin phototypes I-VI, even those with very fair hair, except hair that is completely devoid of pigment (gray and white). At the same time, this type of laser is the most effective, as it allows you to get rid of growth in a specific area in just four procedures.
How to find the perfect laser hair removal machine
Of the diode lasers on the market, the LightSheer DUET device attracts attention. Its fundamental difference from other devices for laser hair removal is an innovative anesthesia system for removing hair in large areas (back, hips, legs). To this end, in the LightSheer DUET, the large area epilation head has been equipped with a vacuum booster that draws the skin into the handle cavity and thereby brings it closer to the laser light source. Pulling up, the skin is smoothed, which makes the hair follicles more accessible for removal. Retraction into the cavity of the handle of the skin irritates the nerve receptors in it in such a way that a change in the modality of the pain impulse occurs. Due to this, a good analgesic effect of laser hair removal is achieved.
For epilation of areas with complex relief (face, armpit) or with difficult access (bikini area), LightSheer DUET uses a small tip with a contact cooling plate, which reduces skin temperature to +4 C.
Due to reliable anesthesia, the procedure of hair removal on the LightSheer DUET device becomes really comfortable. Additional advantages of the device are its versatility in use for all skin phototypes and the need for fewer procedures compared to alexandrite and neodymium lasers.
