Peculiarities
Let's find out what a diode laser is? Today this is the most modern and safe device in the line of lasers for hair removal.
The wavelength of the diode laser beam (800-940 nm) is selected so that it is absorbed by the pigments of the hairs located under the skin, while other skin tissues are not affected. Therefore, the laser hair removal procedure with this laser is the most gentle and effective at the moment.
The “target” of the laser beam becomes the hair root, namely the cells responsible for hair growth. Under the influence of the laser, they heat up and stop working, which is why, as a result of the procedures, hair growth stops almost forever.
This type of laser generates about two pulses per second in duration.
This is interesting ! Cosmetologists of Ancient Egypt knew different methods of hair removal; recipes for hair removal creams based on honey, beeswax and medicinal plants were found. Hair was also plucked and shaved.
Harm of diode laser hair removal
Despite the excellent positive results, DLE can also have unpleasant consequences. Serious side effects are rare. They usually appear due to insufficient qualifications of the person who performed the procedure. A clinic for laser treatment must be chosen carefully, otherwise there is a risk of encountering problems such as:
- fear of light, conjunctivitis;
- loss of vision in the absence of protective glasses and the laser beam hitting the retina;
- exacerbation of skin rashes of an infectious nature.
Most of the consequences of diode laser hair removal are expressed in visible “perturbations” of the body to interference in its work. They are noticeable within 2-4 hours after treatment. It can be:
- redness or hyperpigmentation;
- burns;
- allergic rashes;
- excessive sensitivity of the area.
The reactions are temporary and go away on their own after a couple of days. If you want to get rid of them faster, you should consult a specialist and get recommendations on the use of healing, soothing medications.
Who is recommended for diode laser hair removal?
The desire to look good and feel confident in any situation is a good reason to undergo hair removal with a diode laser. Indications for the use of this type of hair removal may be:
- naturally dark skin, for which photoepilation and hair removal with an alexandrite laser are not suitable;
- skin prone to hyperpigmentation and freckling;
- ingrown hairs and other side effects when removing hair with wax or other methods;
- hair that is naturally coarse and difficult to respond to other hair removal methods;
- hair removal on the face and other delicate areas of the body.
This is interesting !
Laser hair removal appeared in the 70s of the twentieth century as a result of an accidental discovery. An American physicist was the first to test the ability of a laser to stop the growth of body hair. The result of “elimination” of unwanted hairs with a diode laser in the photo (before and after).
The operating principle of both types of hair removal lasers
Before we talk about the differences between the two types of lasers, let's find out what the operating principle of each of them is.
The operation of diode lasers is similar to the action of light-emitting diodes or LED lamps. Their design is made of semiconductor elements that convert an electrical impulse into light rays of the desired length and color. The diode device generates powerful rays that heat the hair follicle. Waves with a length of 808 nm affect the bulb, blocking the access of nutrition to the hair, thereby lightening and thinning it.
The Alexandrite laser began to be used in aesthetic medicine earlier than the diode laser, but unlike the latter, it is used not only for hair removal. This type of apparatus is based on the mineral alexandrite, which is grown artificially. This type of laser emits waves with a length of 755 nm, which is considered optimal for the skin when entering its deep layers or on the surface.
Diode laser - wavelength 808 nm
Alexandrite laser - wavelength 755 nm
To have a more complete understanding of the operation of these 2 types of lasers, I have compiled a comparative table of their characteristics:
Alexandrite laser | Diode laser |
Suitable for fair skin | Suitable for light and dark skin |
Works on dark and light hair | Works on dark hair, but does not work on gray hair |
Tanning should be canceled 10 days before hair removal | You can sunbathe before and after hair removal |
The standard course is 5-8 procedures | The standard course is 8-10 procedures |
Anesthetic gel may be used, but is not necessary. | A gel is used during the procedure |
During the procedure, hairs on the surface of the skin are eliminated | The hairs are not eliminated, but fall out after some time, since the device affects the vessels that feed the hairs |
The number of procedures is less than with diode, so the final cost of the full course may be more expensive | There are more procedures, but the price per session is cheaper |
Advantages
The use of a diode laser for hair removal, according to experts, is becoming the most popular method of hair removal, because it has the following advantages:
- Durability and aesthetics of the result. After the session, the hairs simply fall out painlessly and without a trace, slight redness goes away within 24-48 hours. There is no effect of coarser and darker hair growing back after the procedure. Hairs do not grow in and do not become inflamed.
- Speed of the procedure. The cosmetologist performs manipulations literally “at the speed of light”; the device quickly moves across the skin, which makes it possible to treat fairly large areas in a short time.
- Precision and versatility. A diode laser for hair removal targets a local area of skin with a beam of light, which allows you to model the contours of hair growth. The diode laser is suitable for hair removal of almost all skin types; it can be used by patients with dark and freckled skin.
- The radiation power of the diode laser must be selected in accordance with the patient’s skin type.
- Painlessness and rapid skin regeneration after the procedure in comparison with other methods of hair removal. During the procedure, a gel is used for light anesthesia. The design of the device provides cooling of the instrument and skin during the procedure. The patient usually feels a tingling sensation in the area affected by the laser
- Safety – mechanical damage to the skin and hair follicle is excluded, so it is impossible to introduce an infection into the body during the procedure. If all skin care rules are followed after a diode laser hair removal procedure, side effects are minimal and the results are as long as possible.

Important ! Observe restrictions on sun exposure before and after the procedure, this will make it more effective.
Types of lasers
In total, there are four main types of lasers for hair removal, which are actively used by masters in their beauty salons:
- Diode. The most popular laser for hair removal of any type.
- Ruby. Low efficiency of follicle removal, impossibility of performing the procedure on light hair. The advantage is the low price of the service;
- Alexandrite. In terms of functionality it is closer to a diode laser, but there is a possibility of getting burned.
- Neodymium. The procedure is quite painful; complete hair removal in a certain area requires multiple visits to the salon;
But diode laser hair removal also has its own varieties. In addition to the so-called “classic” - dark hair removal, there are other varieties.
- Elos hair removal. Removing blonde hair. The procedure is painful and expensive.
- Laser cool hair removal. The most effective and safe procedure. Rarely used in beauty salons because it requires highly qualified workers.
Reviews from patients who have undergone the procedure indicate that the best results are obtained by combining classic hair removal and elos hair removal.
Popular diode laser models:
- MeDioStar;
- D-Las;
- DiodIV;
- LightSheerET;
- AnchorFree;
- DUFLEX;
- SopranoXL;
- ADSS.
Advantages and disadvantages of diode laser
Each hair removal option with these lasers has its own advantages and disadvantages. The newest, actively gaining popularity, is the diode laser. And although the procedure is not as painless as its advertisement says, reviews about it are very positive.
Advantages of a diode laser:
- The same effect works with hair of any type and color.
- Possibility of hair removal on tanned skin.
- Painless procedure.
- Safe removal of unwanted hair.
- Complete baldness of the desired area occurs after 4-6 laser therapy sessions.
- No redness, skin irritation, thermal burns.
- The maximum procedure time is 60 minutes.
- Most follicles are permanently affected from the first session.
- Removes blackheads on the chin that appear after shaving.
Minuses:
- Epilation of tanned skin is less effective than light skin.
- Light hair requires much more treatment sessions than dark hair.
- High cost of the procedure.
- Unpleasant sensations during the procedure (mild pain).
The pain of the procedure also depends on the area where the procedure is performed. The skin on the face is thinner, and the nerve endings are located close to each other, making the procedure somewhat unpleasant. But only small pricks are felt on the legs or in the bikini area.
Contraindications and disadvantages of diode laser
Before performing hair removal with a diode laser, the cosmetologist is obliged to tell the patient about contraindications, clarify his state of health and the absence of allergic reactions.
Temporary contraindications:
- Inflammatory processes, injuries and burns at the procedure sites.
- Exacerbation of chronic diseases.
- A tan.
Breastfeeding and expectant mothers do not undergo laser hair removal procedure; this is due to hormonal processes in the woman’s body.
Permanent contraindications:
- Diabetes,
- Diseases of the thyroid gland, cardiovascular system, and pelvic organs.
- Oncological diseases
- Varicose veins and other vascular pathologies in the hair removal area.
If increased hair growth is caused by hormonal imbalances in the body, laser hair removal may not be effective.
This method is also ineffective for removing colorless and gray hair. A neodymium laser is used for this.

Preparation before the procedure
For successful hair removal with a diode laser, the following preparation is needed:
- 1.5-2 months before the procedure, you should not use depilatory creams or remove hair with wax, sticky strips or tweezers.
- The procedure is carried out on untanned skin; at least 10 days must pass from the moment of exposure to the open sun.
- A day or two before the session, you need to shave the hair in the epilation area, the permissible hair length is 1-1.5 mm and do not apply any creams or deodorants to the skin for 24 hours.
Information ! For complete disappearance of hair, it may take from 2 to 5-7 sessions. This depends on the individual characteristics of the patient and the care of the hair removal area after the procedure.
How is the procedure done?
Before hair removal, you should consult with a specialist - he will identify possible contraindications and select the duration of the course.
DLE begins with preliminary preparation at home. The patient must refuse other types of hair removal one month before the procedure. Vegetation in selected areas can only be removed with a razor. You should avoid tanning for 2 weeks before the procedure. Before going to see a specialist, you also need to:
- shave the area 1-2 days in advance so that the hairs have time to grow a couple of millimeters;
- scrub the skin, removing dead cells;
- Avoid oily body care products - they can cause burns.
The procedure itself begins with the application of local anesthesia. Afterwards, the patient can be provided with glasses that will protect the eyes from flashes of light (not required for the latest generation lasers), and placed comfortably on the couch. Depending on the size of the area, treatment lasts from 10 minutes to 2 hours. Up to 5-6 hours, if you need to get rid of vegetation in several zones at once. The device is passed over the surface of the skin, and despite anesthesia, the sensations may not be pleasant. To reduce pain and speed up recovery, after manipulation, healing compounds like Panthenol are applied to the area.
Skin care after the session
Immediately after the session, the cosmetologist treats the skin at the epilation site with a professional product that contains cooling components, panthenol, and vitamins.
To care for the hair removal area after 2-3 hours, you can use panthenol and light moisturizers. Read more about skin care after laser hair removal to achieve the best results.
After the procedure it is not recommended:
- take a hot shower or bath for a day, actively engage in sports;
- 10-12 days of sunbathing and visiting a solarium, infrared sauna, and steam bath.
Information ! The body's individual reaction to the procedure, the rate of hair loss and regrowth may vary from patient to patient.
Principle of operation
To understand where photons come from, consider the process of recombination (the disappearance of a pair of free carriers - an electron and a hole).
When direct voltage is applied to the pn junction of the diode, injection occurs, i.e. a sharp increase in the concentration of nonequilibrium carriers. During the injection process, electrons and holes moving towards each other recombine, releasing energy in the form of a particle - a photon and a quasiparticle - a phonon. This is how the spontaneous emission observed in LEDs occurs. In the case of a laser diode, instead of a spontaneous one, it is necessary to launch the mechanism of stimulated emission of photons with the same parameters. To do this, an optical resonator is formed from the crystal, passing through which a photon with a given frequency forces the electronic carriers to recombine, which contributes to the appearance of new photons of the same polarization and phase. They are called coherent.
In this case, laser lasing is possible only in the presence of an excessively large number of electron carriers at the upper energy level, released as a result of injection. To do this, use a pump current of such strength as to cause an inversion of the electron populations. This phenomenon refers to a state in which the upper level is much more populated by electrons than the lower one. As a result, the emission of coherent photons is stimulated.
Further, such photons are repeatedly reflected from the edges of the optical resonator, triggering the launch of positive feedback. This phenomenon is of an avalanche-like nature, as a result of which a laser beam is born. Thus, the creation of any optical generator, including a laser diode, requires the fulfillment of two conditions:
- presence of coherent photons;
- organization of positive optical feedback (POF).
To prevent the formed beam from scattering due to diffraction, the device is equipped with a collecting lens. The type of lens installed depends on the type of laser.
Areas and cost of the procedure
In cosmetic clinics, prices for diode laser hair removal depend on the part of the body on which the procedure is performed. The range of prices for treatment of one zone in one salon depends on the density of hair growth in the patient.
- full face – 3000-4000 rub.
- upper lip – 1200-1300 rub.

Reviews
My annual course of laser diode hair removal has ended, so I want to share my impression of this procedure, which is gaining more and more popularity. I did everything in a complex: deep bikini, armpits and legs. And after the first session I saw the result. The hairs began to grow more slowly and were soft. During the procedure itself, I did not experience any pain. It felt like I was being warmed by a sunbeam, as it was warm due to the movement of the laser. After several more sessions, the hairs began to grow less frequently. That is, if, for example, three hairs grew, then only one or two began to grow. There was no redness, inflammation or ingrown hairs. I went to sessions for a year once a month. After twelve sessions, the hair grows very slowly, its quantity has decreased significantly and it has become as soft as fluff. There are about ten hairs left to grow under my arms. Now, to maintain the results, you need to visit the center once every three months.

I decided to go with a diode laser, MeDioStar brand. I learned about him that he is supposedly one of the most modern. I found a salon in my city that works with this laser. They just had a promotion, armpits + deep bikini 5,000 rubles. The first procedure was hell for me! I was in a lot of pain and scared, because I encountered a laser for the first time. During the consultation, a cosmetologist-dermatologist examined me, explained the principle of action, the required number of procedures, at least 10 with a frequency of 30–40 days, and the wave power that would suit me. I have coarse black hair and dark skin, I really love tanning. Immediately she brought me down to earth and said miracles don’t happen! Everything is very individual, the result largely depends on the hormonal background. And even after 10 procedures, it is necessary to do maintenance procedures once every six months or a year. I am very pleased with the results, they even exceeded my expectations! There is about 15% hair left in the armpits, in the bikini area the result is a little worse, but I think this is due to the fact that the hair there is very thick. About 30 percent of the pubic hair remains. Still, I highly recommend this procedure. Everything is going exactly according to plan, as the cosmetologist promised. But, again, you need to find a good clinic and specialist. Be sure to strictly follow all recommendations and observe the frequency of procedures.

I chose the Alexandrite laser for myself, because according to the reviews I found, it is the most effective. At the moment, I have done laser hair removal with the Alexandrite laser only 2 times. The first time was somewhere at the beginning of winter. The second is at the beginning of spring. And these two procedures were enough for me to get rid of 95% of the hair in this area. I plan to go for the third time most likely in early autumn, since I read in the summer that it is not advisable to do laser hair removal. In terms of painful sensations, of course, there is little pleasant. The laser hair removal procedure reminds me of small burns. It’s as if a hot object is brought to the skin and it burns a little. But the pain goes away quickly. Am I satisfied with the effect? Yes, 100% sure. The fact is that the master told me that most likely I would need about 4 procedures to completely get rid of hair in this particular area. And in others up to 10 times. As it turned out, the effect even after 2 procedures was very pleasant for me.

I did laser hair removal, but not with a diode, but with an alexandrite laser... lower legs 12 times, still a third or a quarter of the hair remained, 6 sessions above the lip, it felt like all the hair remained (((But in general, they say that it all depends on hair color and structure.

Description of the procedure
Before carrying out the manipulation, the dermatologist is obliged to collect complete information about the patient’s health. The doctor pays special attention to the client’s skin type and hair color. A modern computer program makes it possible during laser hair removal to achieve not only the removal of unwanted hair, but also pigmentation and spider veins.
Next, the patient is asked to lie down on a chair and put on dark glasses. A clear cooling gel is applied to the treated area. It absorbs the thermal energy that is released during flares. This allows you to completely eliminate the negative impact on the skin. The area is then treated with a laser. The tip of the device is made of sapphire glass.
The hair follicle is destroyed by periodic flashes of light. At the end of the session, a moisturizer with a softening effect is applied to the skin. As we were able to verify, you can safely choose a diode laser for hair removal for hair removal. Reviews about it are mostly positive.
Rehabilitation period
If redness or irritation appears on the skin after the procedure, such well-known medical products as Bepanten and Panthenol can effectively deal with them. In the first time after the session, in order not to injure the skin, you can use only those products that do not contain abrasive particles.
After a diode laser hair removal session, you should not sunbathe for two weeks, since the skin during this period is very sensitive to ultraviolet radiation. If the procedure is carried out during periods of active sun, then experts recommend using sunscreen with a protection factor of at least 30 SPF.
What it is?
Laser hair removal is a modern method of removing unwanted hair on the face and body. With the help of a diode laser, not only hard dark hairs are eliminated, but also light, thin hairs, which, as we know, can be more difficult to get rid of. The bulbs exposed to this tool are gradually destroyed.
The laser, emitting a light wave of a certain length, destroys melanin, a pigment contained in the follicles and hair shafts. This flash of light leaves skin smooth and silky forever.
