The device removes hair well, but the result of the procedure cannot be assessed immediately. It goes on increasing from procedure to procedure. It becomes clearly visible only after several procedures, and the final result after 10-12 sessions.
The disadvantages include the high (compared to waxing and sugaring) price, but this is fully compensated by the duration of the effect.
After hair removal, the skin often remains highly sensitive for some time, redness and swelling appear. Do not worry if the symptoms last from 3 hours to 3 days (this depends on the individual characteristics of the body). Then they should disappear.
Rating of the best lasers
Many of the devices are combined models that use beams of different wavelengths.
5th place belongs to Synchro Excellium HP from the Italian company DEKA. This is a multifunctional device that can be used to remove tattoos, spider veins, pigment spots, and epilate hair of different thicknesses and colors on any part of the body.
4th place goes to VS-150. The device combines 2 lasers: alexandrite and neodymium. It is used for hair removal, removal of pigmentation and spider veins, and rejuvenation procedures. The most important thing is the relatively low cost of the device.
3rd place goes to GentleYag Pro-U from Candela. The device features a dynamic cooling system and more durable sapphire crystals. It has a clear and easy to navigate menu. The device is fast and powerful in operation.
2nd place belongs to Lasertech Combine. The device combines a neodymium laser and an Elos epilator. It is easy to use and versatile: it removes permanent makeup, acne, age spots, rosacea, polishes scars, performs hair removal and peeling.
1st place is occupied by “Foton” lasers produced in Slovenia. These are devices based on Er:YAG and Nd:YAG. According to reviews from cosmetologists and patients, they are called the best. Laser systems allow you to perform a wide range of procedures on the face and body.
All models in this review are comfortable and easy to use. They are multifunctional and are suitable not only for hair removal.
Main mistakes when choosing a neodymium laser
First mistake.
Associated with a misunderstanding that the two modes are essentially two different handles. It is impossible to switch to long-pulse mode with a Q-switch in the handle
Second mistake.
Leading clients on marketing moves: our neodymium removes pigment in 1-3 procedures; or works with unwanted colors: green, yellow or white.
Third mistake.
Regardless of the manufacturer, the nature of the working fluid or the interaction of infrared light cannot be changed. Therefore, do not limit yourself to the opinion of one specialist and collect information carefully.
Fourth mistake.
It is also a mistake to purchase a low-power or, on the contrary, a super powerful device. You need to choose a device of medium power, with a high-quality single crystal, a double cooling system: water + air, with a simmer board, which will ensure comfortable work for you on stream.
What should you pay attention to when choosing?
- Crystal quality
- Device power
- Device cooling system
- Availability of components
- Ease of use
What laser characteristics are important for a successful result?
- How pure is the crystal?
- Device power
- Availability of laser target pointer
- The volume of the water tank, since water is the cooling element for the crystal
How do you know if you can trust a seller?
Pay attention to the company's experience.
For a biography. This is a very important point that will help you understand where the company started and where it is now.
Let's take our company as an example.
The Lasertech company began its work with the opening of a tattoo parlor, which became very popular. Against this background, the question of tattoo removal arose. And for 11 years now, the company has been not just a seller of neodymium lasers, but also a developer of the best of them.
- Pay attention to the reviews from those. specialists who work in this industry.
- Look at the documents: certificates of conformity; certificate that you receive at the training.
- Customer focus and company loyalty.
- Management team.
- Marketing support team.
- Engineering service team.
- A doctor who shares his experience and knowledge.
All this is very important. Each point provides an overall picture of trust in the company.
Colleagues, now we can answer the question:
Prices
Neodymium laser for hair removal gives good long-term results, but this procedure is not cheap. At the initial appointment, the specialist will conduct an examination, give recommendations, and, depending on the area of hair removal, name the cost of the course.
Hair removal in the chin area will cost an average of about 2,500 rubles, in the upper lip area - from 1,500 to 3,000 rubles, along the bikini line - on average 7,000 rubles, buttocks - 8,000 rubles, hips - 12,000 rubles.
You can buy the device itself in the online store. The price for it will depend on the manufacturer and its main characteristics. For example, Magic ONE can be purchased for 1,500,000 rubles.
Recovery
Recovery after laser does not require long-term rehabilitation in special conditions. There is no skin irritation - only moderate redness, which disappears quickly. Therefore, maintenance procedures are not particularly required - skin and hair regeneration is very high, but to maintain ideal skin condition, it is enough to undergo a session once a year.
Our clinic is ready to provide all kinds of discounts to regular customers, services of qualified specialists and professional equipment. We care about our patients and their health. Our prices are quite reasonable and acceptable, and we are always happy to see you in the branches of our clinic.
What color hair is it used for?
Neodymium lasers appeared on the market as devices that can work with any skin phototype. They even suit African Americans. Unlike alexandrite, their work does not depend on the amount of melanin and is aimed at the vessels that are located next to the hair follicles. This is why they are popular, despite the pain of the procedure itself.
Devices of this type are suitable for salons and clinics that offer patients a full range of cosmetology services. They work on dark, red, blond, even gray hair and are always safe.
What are the differences between neodymium lasers?
Short pulse mode
This mode means that light flashes are ultra-short in time, measured literally in nanoseconds. The peak power in each flash is quite high, at which an acoustic wave is also formed. It also takes part in the removal of pigments and can be heard during operation.
The pigment, under the influence of these factors, literally fragments into particles, which within a sufficient amount of time will leave the affected area in some quantity.
Using a wavelength of 1064 nm is appropriate for dark-range artificial pigment and deep-lying natural pigment.
Using additional wavelength 532 nm, which was created artificially using a separation lens, is suitable for all shades: artificial red or superficially located natural pigment and post-acne.
The Q-switch, which is located not in the device, but in the handle, is responsible for the formation of short pulses.
Long pulse mode
It is characterized by the expansion of the pulse in time in milliseconds, taking into account the thermal relaxation time of the skin and chromophore. In order to coagulate a vessel, you need a pulse of such duration that the hemoglobin absorbs light as much as possible and heats up, and the skin has time to cool down between pulses. This is only possible in the LONG PALSE mode.
It is a big mistake to undertake the removal of blood vessels, for example, with a short-pulse laser, since during the light pulse the hemoglobin does not have time to heat up, coagulation does not occur, and the skin between flashes overheats enormously. This leads to disruption of the integrity of the skin, 1-2 degree burns.
Indications for deep dermal rejuvenation
- decreased skin tone
- sagging skin, loss of elasticity and firmness
- gray dull complexion
- owners of enlarged pores
- signs of aging and fading of the skin (network of small wrinkles, folds, slight sagging of tissue, etc.)
- stagnant spots after acne
- vascular changes
- for preparation for a surgical rejuvenation procedure or after its implementation as a restoration
- prevention of skin aging.
Which one is more convenient for a cosmetologist to work with?
A specialist, choosing the direction in which he wants to develop, determines the services that he will provide to his clients. If it is tattoo removal or carbon peeling, then it is worth considering the neodymium Q-switch laser, as it meets these needs.
And if you are engaged in epilation, then the absolute right choice will be a diode laser, since this is, perhaps, the only laser among epilators that works on the principle of selective photothermolysis, where there is a simple truth: light absorption should pass through only one chromophore in order to eliminate the occurrence of side effects and improve results.
Contraindications for laser hair removal
After completing a course of laser therapy using a neodymium laser, you will be able to see for yourself that this is a very modern and effective method of solving the problem of unwanted vegetation.
However, not everything is so simple, and in any case we must not forget about possible contraindications. For example, it is worth delaying laser hair removal for women during pregnancy and lactation, people with infectious and skin diseases in the area where the procedure is to be performed, blood clotting disorders, signs of a fresh tan (the solarium and the beach should not be visited at least two weeks before the next session), as well as psychological diseases (especially epilepsy).
It is also undesirable to perform laser hair removal if the skin is damaged or the presence of malignant neoplasms is suspected. In all these cases, instead of a positive effect, you will simply aggravate the existing problem, which, of course, is very undesirable.
Fluency and spot size
Fluence (energy flux density) is the most important parameter on which the effectiveness of laser hair removal depends. This parameter means how much laser energy is transmitted per unit of skin surface during the procedure. The larger it is, the more energy will be delivered to the hair follicle. The fluence is directly related to the energy and power of the laser device, but is not an analogue of these parameters, but depends on the area of the spot size. With a radiation energy of 100 joules (J), the distribution of this energy over a spot measuring 1x1 cm will give a fluence of 100 J/cm2. The same energy of 100 J distributed over a spot measuring 2x2 cm will give a fluence of 25 J/cm2.
When choosing a laser device, you should be interested not in its energy, but in its fluence, as well as the range in which this fluence can be changed. An hair removal laser with a low maximum fluence may be ineffective in some cases, for example for removing coarse (large diameter) hair.
The size of the spot is also an important parameter. Firstly, as the spot size increases, the proportion of scattered light decreases and, as a result, the penetration depth increases, and hence the efficiency in epilating deep-lying hair. Secondly, the large spot size allows large areas to be treated at high speed. For example, with a spot size of 2.2x3.5 cm, epilation of a man's back will take about 10 minutes, and with a spot size of 1x1 cm - more than an hour. However, despite the fact that the small size of the spot requires the use of a larger fluence, it cannot be completely abandoned, since it is needed for hair removal in hard-to-reach areas, for example, above the upper lip.
Influence of spot size on the penetration depth of laser radiation. As radiation penetrates the skin, it is scattered, so as the size of the spot increases, the depth at which the effective fluence value will be achieved will increase.
Do I need special care after hair removal?
A slight reddening of the skin in the treated area is considered normal after laser hair removal. It should disappear within a few hours without causing any discomfort.
In addition, for a certain time after the procedure, the skin remains quite sensitive, and it can be damaged by sunlight, which is why you should not visit the solarium or the beach for at least several weeks after the session.
If the hair removal procedure using a neodymium laser occurs during a time of high solar activity, be sure to apply sunscreen with a high protective factor before leaving the house. No additional care is required.
Find out how to properly care for your skin after laser hair removal. What to do to get better results.
Some time after epilation, you may notice the so-called “false hair growth ,” which is caused by the gradual pushing of “dead” hairs to the surface of the skin. It is quite simple to distinguish them from those that are actually growing: by pulling them with tweezers, you will not feel any discomfort or pain. Don't worry about them, they will fall out on their own.
Working principle of a diode laser
Diode laser or semiconductor lasers are the most common type of lasers in cosmetology, which are used to provide anti-inflammatory effects, for example, for hair removal or rejuvenation.
Semiconductor lasers are pumped by a strong forward current, and the Peltier element cools the laser tip to prevent overheating of the skin from such powerful light energy. By the way, the wavelength of light emitted by the diode handpiece is 808 nm.
Now let's remember
Main advantages
Compared to alternative methods, neodymium laser is considered safer. In addition, it shows the best results when working with tattoos and permanent makeup. Short pulses “split” the paint lying under the skin into smallest fractions, and subsequently it is removed from the body by the lymphatic drainage system. On average, the result is assessed after a month.
In our clinic, to carry out this procedure, we use a device from the famous German manufacturer “Asklepion”. This type of laser is distinguished by its well-thought-out design, convenience and ease of use, has passed all the necessary clinical tests and is actively used by cosmetologists around the world.

Pulse duration and series of sub-pulses
It takes some time for the heat to spread from the heated hair shaft to the stem cells of the follicle. This means that short-pulse lasers are not suitable for laser hair removal; or rather, the use of such lasers will burn out the hair shaft, but may leave the follicle stem cells undestroyed. Typically, laser hair removal uses pulses lasting from 10 to 100 milliseconds or more. Moreover, short pulses are suitable for thin hair, and long pulses are suitable for thick, coarse hair.
A good property of a laser for hair removal is the ability to emit a series of sub-pulses with short intervals between them. This method allows you to gradually warm up the hair shaft without the risk of damaging the epidermis: in the intervals between pulses, the epidermis has time to cool down, but the hair does not.
Effect of neodymium rejuvenation
Rejuvenation with a neodymium laser activates the cell regeneration mechanism, while new collagen and elastin fibers are created. After completing a course of procedures, you can notice a good rejuvenating effect. In addition, neodymium laser has a bactericidal effect, thereby healing the skin and relieving inflammation, and also removes blood vessels. As a result, the patient will be able to observe positive changes:
- skin firmness and elasticity are restored
- the face takes on a more youthful and toned appearance
- pores become narrower
- complexion looks healthy and natural
- the network of small wrinkles is smoothed out, and pronounced ones become less noticeable
- superficial vessels are eliminated
- the severity of stagnant acne spots decreases.
Use of lasers for hair removal in Russia
All lasers for hair removal belong to medical devices, this is clearly interpreted by Part 1 of Article 38 of the Federal Law of November 21, 2011 No. 323-FZ. Therefore, before purchasing a device, you must make sure that it has a valid registration certificate from Roszdravnadzor. You can check this on the website www.roszdravnadzor.ru. Laser hair removal is included in the list of cosmetology works and services related to medical activities (established by the Federal Service for Surveillance in Healthcare and Social Development of the Russian Federation). Finally, the laser hair removal procedure itself is carried out in a specially equipped room - a hardware cosmetology room.
The law clearly defines hair removal lasers as medical devices and laser hair removal as a medical service. This means that laser hair removal can only be performed in a beauty industry enterprise that has a medical license, and the laser hair removal device must have a registration certificate from Roszdravnadzor.
Some unscrupulous sellers mislead buyers by offering laser devices registered as household devices and promising the ability to operate them without a medical license. Buyers of laser hair removal devices without a registration certificate and specialists working with laser devices in institutions without a medical license are breaking the law. The penalties for this violation can be very serious, including criminal liability.
