The principle of exposure to laser hair removal

In pursuit of beauty, women are often ready to make any sacrifices. The removal of excess vegetation on the body has long become a necessary and familiar hygienic procedure. Traditional methods of hair removal by shaving, wax strips or a mechanical epilator require regular repetition, moreover, they can act as the causes of irritation and inflammation of the skin, as well as ingrown hairs. Laser hair removal will help maintain the health of the epidermis that fundamentally eliminates the problem of excessive vegetation. This procedure allows you to safely and effectively get rid of unnecessary hairs. Thanks to the targeted effect of the laser, the destruction of hair follicles is observed (while experts assure that in the effectiveness of the impact on them, other procedures will not be equal to laser hair removal).

This method is based on the principle of selective effects of the directed light flow on a variety of biological structures. The hairs of hairs, as well as in their follicles, contains the color pigment melanin, which absorbs light waves. Under the influence of light energy, the pigment is largely heated, which leads to damage to the sprout zone surrounding the roots of the hairs. After some time (after about two weeks), the processed rods along with the destroyed roots gradually fall out.

Advantages of laser hair removal

The advantages of laser hair removal include:

safety of this method for health;
the comfort of the procedure and a gentle effect on the skin without damage to the skin;
removal of ingrown hairs;
the possibility of use at any time of the year, as well as in the presence of sensitive skin;
efficiency - as a result of the course of laser hair removal, you can get rid of unwanted hair for a long time (ideally - forever). From a session to a session, the number of growing hairs will decrease.

As a result of the first procedure using a laser, it is quite possible to get rid of at least 15% of the hairs.

Laser hair removal: why is a course of procedures

It is worth noting that a single laser hair removal session to remove unwanted vegetation is not enough for a long time. It is known that the hair grows cyclical, and at the same time is in various phases of growth. Thus, hair follicles can remain:

in a period of rest, when the bulbs are in a sleeping state;
in an active growth period, when they become quite “mature” and contain the maximum amount of melanin;
in the intermediate phase.

According to statistics, up to 80% of actively growing hair can be observed on the body, the rest temporarily abide in the rest phase. Light radiation affects the color pigment - as a result, after laser hair removal, the destruction and elimination of “mature” hair is observed, which are at the time of processing are in the phase of activity. At the same time, the follicles are damaged, but total destruction does not occur, and over time the hairs can grow, but already thinner and weakened. In addition, after a while, “sleeping” hair sprouts, and then they can be removed. This phenomenon can be observed cyclical-a complete change of hair can be occupied from 8-10 months to several years, depending on the individual characteristics of the body. During this period, you can plan the use of a course of laser hair hair removal procedures with a frequency of three weeks to a month and a half.

Sometimes you can hear a promise for a couple of sessions of the influence of a laser to completely eliminate any undesirable vegetation. It is worth considering that such promises do not have real grounds. It is necessary to take into account the following data - according to statistics, after applying the minimum number of laser hair removal sessions (a series of four procedures), a growing of less than 40% of the hair can be observed after 4 years. Nevertheless, two or three sessions in most cases are enough to remove minor antennae on the sides of the upper lip. Several laser hair removal procedures will help eliminate the most stringent dark hairs in fair -haired people and make the rest less noticeable. Thus, the speed of elimination of unwanted vegetation is individual, while in most cases it is quite predicted. The required number of sessions is determined by the type and condition of the hair, as well as the power of the equipment used.

Laser hair removal: contraindications and restrictions on the application of the procedure

It should be noted that there are a number of restrictions on the use of laser hair removal.

Contraindications to this procedure are the presence:

immune disorders;
tumor processes;
decompensated diabetes;
systemic skin diseases (psoriasis, eczema, etc.);
acute or chronic herpetic infection;
exacerbations of allergies;
individual intolerance to this procedure.

Laser hair removal should not be used during pregnancy and breastfeeding, as well as after a recent stay in the sun (if there is a tan less than two -week ago). You should consult a doctor in the presence of varicose veins, multiple moles on the skin, a tendency to form keloid scars. Due to the specifics of the procedure, laser radiation will not be able to remove very blond and gray hair.

Laser hair removal: used equipment

To remove unwanted vegetation on the body, laser installations of various types can be used, with different waves of the wave and the used cooling methods. It is known that hair follicles are placed in an epidermis at a depth of 0.2-0.4 cm. Depending on the color of the skin and hair type, radiation with a wavelength of 690 to 1000 nm can be used. For exposure to hair follicles, which are placed at a significant depth (about 4 mm), sufficiently powerful devices with a wavelength of 1000 nm can be used.

Depending on what types of rods are used, the following types of lasers are distinguished:

rubin - this apparatus with a wavelength of 694 Nm represents the first generation of laser epilators and differs in low speed. The light energy during its use is noticeably dispersed, while the risk of skin damage increases;
alexander - characterized by a wavelength of 755 Nm and a speed of several pulses per second, which is very convenient for processing the hair growth zone;
neodymal - this laser is designed specifically for dark and very dark skin. Laser installations of this type are of significant power. The wavelength of such laser epilators is 1064 nm, while a slightly different principle of exposure is applied. A coal suspension is rubbed into the skin - thus, when heated damage to the cells surrounding follicles, they are thermal and mechanical;
diode, or sapphire - installation of this type is very convenient in use, radiates a luminous flux with a wavelength of 810 nm. It is worth noting that this indicator is currently considered optimal for hair removal.

In modern laser installations, radiation is used that can penetrate deep into the epidermis, followed by damage to the hair follicles located there in various phases of development. If you choose between laser hair removal or photoepilation, you should give preference to the first option. When conducting photoepilation, radiation with a non -fixed wave that changes in the range from 600 to 1050 nm is used (thus, it is possible to achieve a less pronounced effect, while part of the radiation is absorbed by the skin).

Laser face hair removal

Unwanted vegetation on the face is able to deliver a lot of grief. Hard and dark hairs often appear in women - they can mainly be observed over the upper lip, eyebrows, as well as in the nose, cheeks or chin. It is dangerous to shave them, because new hairs grow more rigid and noticeable. Hot wax can burn the skin, cream for depilation - cause irritation or allergies. In addition, hairs grow again and at the same time very noticeable. It is not difficult to cope with such a problem by applying laser facial hair removal - with its help you can remove individual hair, as well as abundant vegetation. In a similar way, you can carry out laser hair removal of the upper lip, get rid of individual hairs growing in the ears and on the neck.

Laser hair removal of the bikini zone

The most comfortable method of removing unwanted vegetation in the bikini zone is laser hair removal. Traditionally, regular procedures are used to remove hair in the intimate area - shaving, depilation using wax strips or sugar paste. After using a razor machine, black dots soon appear on the skin, after two to three days you have to shave again. The effect of wax depilation is longer, but even after it no one is safe from irritation. The laser hair removal of the bikini zone, which differs in the following advantages: can be a way out in this situation:

this method of hair removal does not leave black dots;
the skin remains smooth;
in this way, you can plunge the processing, including hard -to -reach places in the bikini zone, which are difficult to process with a razor;
after applying a series of procedures, it is quite possible to get rid of vegetation forever.

Deep laser hair removal allows you to carefully treat the skin as carefully as possible in a given delicate area.

Features of the laser hair removal procedure

It is worth considering that within a month before the epilation session, you should not sunbathe. Within 4-6 weeks before it, as well as in the intervals between procedures, you should not remove hair with methods that injure hair follicles (for example, using wax depilation). 1-2 days before the session, you will need to shave the hair in the planned processing area.

The price of the procedure depends on the level of the clinic, as well as on the area of \u200b\u200bthe hair site. Sometimes the type of processed zone is taken into account, as well as the number of laser outbreaks. At the preliminary consultation, the specialist examines and defines the client’s phototype, and then, based on data on the susceptibility of the skin and hair to the light, selects optimal exposure parameters and set up a laser installation.

In fact, the procedure itself is simple. Before starting it, the master and client will need to wear goggles. The device is sequentially treated with the device, while the laser produces short light pulses. Thanks to the dynamic cooling system built into the laser installation, the skin calms down with the spraying of cryogen, while the possibility of irritation and burns is excluded. If necessary, before the session, the doctor will process the skin with a special cream with an analgesic effect. In the presence of a high pain threshold, an hour before the start of the procedure, you can take an analgesic drug.

Within 10-12 hours after laser hair removal, slight redness and irritation can be observed, as well as numbness or tingling of the skin. During this period, it is not recommended to take a shower or a bath, rub the skin, treat it with alcohol -containing drugs, as well as a scrub. Within three days after epilation, you should not visit the sauna and pool, in addition, it is not recommended to sunbathe for two weeks.
