The method does not require much time, relatively painless and inexpensive.
The main problem however is that not all places, which is offered laser hair removal can ensure quality service.
Devices are often poor or working with them are not well trained. Are not rare and cases of dangerous side effects such as burns or the formation of pigment spots.
A selective laser Hair Removal is fototermoliza.
Lasers cause localized damage by selectively designated hot spare tissues while the rest of the skin.
Individual in this light energy is absorbed by melanin in hair, accumulates and is converted into heat. Then it is transmitted in depth as a result of burns the hair follicle and root.
Pigments in the skin also bear part of the laser energy, but because of the different characteristics of the tissue can be achieved burning hair in depth, not hurting epidermis.
In general, you can summarize that the results of hair removal depends on the following conditions:
Power apparatus – to good effect to deliver enough energy into the hair. It is not enough only to burn themselves hair, but should be pridizvika and damage to the hair follicle, and nest.
More powerful device provides faster coverage of the treated area, which reduces the duration of the procedure and discomfort in the patient.
Pulse shape is a crucial factor. As mentioned above, laser light is absorbed by melanin, which contains not only the hair, and the skin.
Thus, in the introduction of energy necessary to kill the hair, inevitably receive superficial burns. This is avoided by the specific shape of the light pulse in order to achieve a sufficient temperature for killing the hair follicle, while the skin remains unaffected.
Qualifications of the doctor performing the procedure. No matter how expensive and quality is an apparatus, caught in inexperienced hands it can lead to poor or even catastrophic effects.
Of utmost importance is the procedure to be performed by an experienced doctor or at least under medical supervision. It is also important to know that for this reason all the quality equipment in the world are held as “medical” rather than “cosmetic devices.
Quality and maintenance of the laser. The market are many companies which said that devices which offer is the same parameters as the leaders in this field.
These devices are really great part of the capabilities of expensive lasers, but the difference is that with them nothing is guaranteed. From accurate safety is extremely important parameters of laser pulse are the same as the doctor has set the display.
Quality devices continuously monitor outgoing power and stop automatically when abnormalities. Each laser should be checked regularly by a qualified professional to make sure its safety and effectiveness.
Objective expectations of the patient. It should be stressed that it is not possible 100% Hair Removal.
The hair is reduced to 85-90%, but then others are very thin, light and grow much more slowly. Light and thin hairs are more difficult to treat, so that sometimes require more procedures than previously planned.
Observing the number of procedures. To achieve the desired effect, irradiated hair must be in active phase of growth (anagen), then the content of melanin is greatest and they are related to the dermal papilla (where the bulb of the hair), which is our core target.
