I went to the salon and asked all the questions. It turned out that the most modern way to remove hair - with the help of ... light. More precisely, light pulses that affect the hair. To increase self-esteem, we teach the professional term "selective photothermolysis". This means that pigmented substances can be selectively heated and destroyed without harm to surrounding tissues. In the case of epilation, this pigment is melanin. It becomes a kind of "target", to which the liquidating effect is aimed. Laser hair removal is of two types - laser and photoepilation.
Laser devices appeared earlier and immediately proved themselves well. Therefore, it is this name that everyone has heard. Photoepilation - a later development, and today it also has a lot of fans. Until now, discussions on what method is more effective have not ceased. But it is the prerogative of doctors to find out the truth. And the main thing is for us to work. And it works as follows: a powerful light beam is directed to the skin area and penetrates under the skin. Further, it moves along the hair shaft and reaches the hair follicle. There the light energy is converted into heat, heats up and destroys it, due to which growth stops. The most interesting thing is that after the course of procedures it does not resume.
Laser show
For laser hair removal, four types of apparatus are used: ruby, alexandrite, diode and neodymium laser. They differ in wavelength and a number of technical characteristics. For "one sitting" the laser is spotted by a spot 10-18 millimeters in diameter. This advantageously distinguishes it, for example, from electroepilation, in which it is necessary to "aim" at each individual hair. Due to the wide coverage, the speed of laser treatment increases many times. The depth of penetration of energy into the skin, and hence the effectiveness of hair removal, depends on the diameter of the pulse.
With photo flash
If the laser wavelength is fixed, then the photoepilation uses light of a wide range of lengths. That is, the length can be changed depending on the type of skin and hair color. Therefore, photoepilation can come to the aid of both natural blondes, and people with dark and dark skin from nature. The exception is gray hair and very blond hair, in which melanin is absent altogether. Another feature of photoepilation - processing is short flashes, and not continuously, as with a laser. This allows you to adjust the intensity of the exposure and the intervals between flashes. All this makes the technique more variable and allows you to customize the device individually for the patient. The range of application of laser hair removal is rather narrow - removal of black hair on white skin. The appearance of photoepilation with ease solved this problem. The physical principle of the action of photoepilation differs from the laser. The photoepilator emits intense light pulses that are generated in a wide spectrum, unlike lasers that operate at a fixed wavelength. This difference makes it possible to achieve striking results for people with swarthy skin and owners of blond hair. Sessions are selected individually, an average of 5-8 procedures with an interval of 21-35 days, depending on the skin area. The action of flashbulbs is painless, the latest generation devices are equipped with a cooling system, which allows to refuse additional cooling of the skin before the procedure. The area of the flash is up to 13 cm2, which is why photoepilation differs favorably from laser light. Thanks to this, the procedure for photoepilation takes only five minutes to half an hour.
Slowly but surely
By and large, both laser and photoepilation fulfill the task - they help women and men get rid of unwanted hair. But a miracle does not happen in one day. Laser hair removal is a coursework procedure, and it is worth immediately attuning to systematic work with your body. Hair growth will slow after the first session, but before they disappear, it will take several months. This is due to our physiology. Both the laser and light flashes affect the roots of only those hairs that are in the stage of active growth. Usually at the time of the procedure this is about 20-30% of the total. Therefore, after several weeks, the procedure should be repeated to work with the hair, which last time "slept." And so several times, to achieve a lasting effect. At a time, hair can be removed only by an X-ray, but I do not think anyone will want to expose themselves to this unprofitable procedure.
With light - in the bright future
So, you can think about the future summer 2011 right now. Thoughtfully choose a clinic, method, consult a doctor and make a test (if the skin is particularly sensitive). The trial effect will give an understanding of what physical sensations will be during the procedure. Laser hair removal will permanently remove hair including ingrown ones. Experts believe that this is generally the most effective way to solve this problem. Does all hair in the area of exposure remove such hair removal? No. It does not affect the fleece hair, which is not necessary - because the skin should be at least some kind of protection from the external environment. Contraindications to light epilation are standard - exacerbation of chronic diseases, inflammatory processes or infections. During pregnancy, too, it should not be done. With a fresh tanning, no hair removal is recommended, so it's better to forget about the solarium during the course of the procedures. But what about the solarium, if by spring I will have smooth legs! I'm already looking forward to throwing out my razor. Finally, the long-awaited freedom! ^
What is a laser?
The word "laser" is an abbreviation of five English words: Light Amplification by Stimulated Emission of Radiation (LASER), which translates as "amplification of light by stimulated emission of radiation". The laser sight is aimed at melanin, which is contained not only in the hair, but also in the skin. Hence the features of laser hair removal: first, it does not work with those hair in which melanin is at a minimum. And secondly, if a person has dark hair and swarthy skin, then the laser does not distinguish one from the other, which can lead to hyperpigmentation. Over time, devices were invented that solve this problem, too - they are aimed at substances in the blood supplying the hair follicle. A beam of light "identifies" the object and acts on it.
