Preparation for laser hair removal: recommendations and rules
Laser hair removal. A method of radical hair removal, which involves the destruction of hair follicles using laser radiation. The procedure has high efficiency and practically does not cause any uncomfortable sensations, and the effect will last many months. To consolidate positive results and reduce risks after procedural complications to a minimum, it is required to properly prepare, which involves compliance with all the recommendations of a specialist.
Proper preparation for laser hair removal is the key to obtaining the desired result and the lack of negative consequences. Therefore, preparatory procedures must be treated responsibly, not ignoring the doctor’s recommendations, ask questions about incomprehensible moments.
Laser hair removal today is one of the most effective methods of radical disposal of unwanted hairline, which has many advantages:
Lack of irritation and damage to the skin;
The procedure is recommended for patients from 18 years old. The technique is suitable for people who have a natural color of the stripes from light red to dark. At the same time, the darker the hairs, the better they remove. The essence of the methodology is to use the destructive properties of the laser on the hair follicle. The laser hair removal apparatus generates radiation, which interacts with the pigment in the hair. Due to this, the hair rod and root are heated, as a result of which the follicle is destroyed, and hair growth stops for a long time.
What to do before laser hair removal and how to prepare for neurbs. Tell a dermatologist-cosmetologist clinic “Medial”. Following the serious recommendation. You will protect the skin from increased thermal load, exclude the risks of pigmentation, burns, peeling and irritation.
Neodymal laser is suitable for removing blond hair on all types of skin, even on the most dark and dark hair on the skin of IV and V photos. In addition, a neodymium laser is the only apparatus that allows laser hair removal on tanned skin. However, when working with dark hair on fair skin, it is inferior to the Alexander Laser in terms of effectiveness.
The diode laser can be called an intermediate link between Alexander and Neodimov. It can be used on light and not very dark skin and to remove only dark hair, t.E. He does not “see” blond and thin hair too well. In addition, there is one nuance and it lies in the fact that after removing the hairs for another 7-12 days remain on the skin and only at the end of this period they disappear.
Elos-epillation is an effective technique that is a combination of laser and electric energy. The procedure promotes the destruction of follicles, which for a long time excludes the appearance of new vegetation. The technology is universal, suitable for any color type, whether it be dark skin or thin, blond hair. Elos epilation is transferred almost painless thanks to the cooling system and the use of local anesthetics in the form of a cream or gel.
Universality that allows you to get rid of hair of any type;
Laser kul epilation
A cold method in which the effect is made by short flashes of a laser directly on the hair, while affecting the tissue follicle surrounding the hair follicle. The procedure is painless, suitable for owners of dark skin.
Does not cause burns, irritations, pigmentation.
Long sessions that can reach 1.5 or more hours.
Cool epilation is a painless and very effective technique using light radiation. The “cold” exposure to the laser excludes the heating of the skin, and the maximum that the patient can feel is a slight tingling.
Using this procedure, you can remove very blond and gray hair. Interval between courses. Up to 5 years.
Disadvantages of QOOL epilation: high cost, the required number of sessions-about 10, the duration of one session is 1.5 hours.
Types of lasers for epilation
Traditionally, they use ruby, diode, Alexander and neodymium lasers for hair removal. Lasers differ in the wavelength and characteristics of the active environment.
Laser Hair Removal by Skin Type [Dr. Ellern Explains How to Make Yours Safe & Effective]
Rubin laser. The first medical laser developed in 1960. Despite such a long story, this species did not lose its relevance. The action is based on a ruby rod from aluminum oxide with chromium impurities. The wavelength is 694.3 nm. The ruby laser is effective not only for hair removal, but for removing pigmentation and even tattoos. This type of laser is effective for removing only dark hair on fair skin. Due to the short wavelength, the energy is actively absorbed by the pigment, because use on dark skin can lead to white spots due to the destruction of melatonin in skin tissues.
The alternative to the ruby laser is Alexander. The basis of his work is the crystal of Alexandrite with the alloying of chrome. Wave length in the range from 700 to 820 nm. This type showed high efficiency in removing dark hair on non.Tight skin. Works well on the owners of Celtic, Nordic or Middle European photos. When working with other types of skin, burns are possible due to the increased content of melatonin in skin tissues.
Diode laser is the third type of lasers actively used to remove hair. This type of laser has a wavelength of about 800 nm, which allows you to remove hair even to owners of dark skin. The diode laser is suitable for working with Celtic, Nordic, Mid.European and Mediterranean photos, and shows high efficiency when removing hair with dark or tanned skin.
The disadvantages of the diode laser are the duration of the procedure, the possibility of discomfort during the procedure or the need for a long course to achieve a persistent effect.
Neodymal laser is the most modern laser among analogues used to remove hair. The wavelength is 1080 nm. Laser power is maximum among other types, which allows the light beam to penetrate deep into the fabric and actively affect the follicles. The neodymium laser, unlike analogues, does not affect melatonin, but on blood hemoglobin that feeds the follicle, as a result of which it does not receive the necessary nutrition and is destroyed. Such characteristics allow you to remove bright, red and gray hair on any skin type. This type of laser is suitable for working with the Mediterranean, Indonesian and African American type, which is its important advantage. In addition, a neodymium laser is actively used to rejuvenate the skin. In general, this type can be used for all photos, but its disadvantage consists in the duration of the procedure and sensitivity for the client.
Regardless of the type of laser used in order to exclude negative consequences, it is forbidden to carry out procedures in the case:
- Pregnancy and lactation;
- The presence of abrasions or damage to the skin;
- Oncological diseases;
- Infectious diseases;
- Diabetes sugar:
- The presence of a large number of moles or age spots.
In modern cosmetology, various types of lasers with different wavelengths are used. There is no laser that would be effective and applicable to all types of hair and skin. Using many expensive laser monolf apparates for each wavelength and skin phototype is not economically profitable. Therefore, there are universal hybrid models of diode lasers on the market (see our rating). Manufacturers offer devices operating immediately in the range of three lengths of waves (Alexandritova, diode and neodymium). To achieve the high efficiency of the epilation procedure, it is important to correctly determine the phototype of the skin and hair, choose the right laser type and settings of the device, this will not only efficiently remove unwanted hairs, but also avoid negative consequences.
Aleksandrite or diode laser to choose with light skin
Candela Gentlelase (Alexander 755nm). A very effective laser for hair removal with light skin types. The laser beam of this wavelength is well absorbed by melanin (skin and hair pigment), which makes it the best option for removing hair with a low phototype, but not the most suitable for tanned and pigmented skin with a high phototype.
The laser beam from the Lightsheer apparatus (810nm diode laser) is absorbed by melanin to a lesser extent than from Alexander. This makes it less effective for thinner or brighter hair in comparison with Candalo, but allows you to use it wider with tanned and pigmented skin. However, Laser Lightshire is not a laser of choice for 6 phototype. In this case, for dark brown or black leather, long-income bully ND: Yag, for example Gentleyag, is preferred.
For thin, light and less pigmented hair with 2-3 photos of Cahdela Gentlelaase. The best way. In Russia, the most common Nordic and medium European versions of the phototype, for them. Aleksandrite laser is a choice of choice.
However, with darker skin, for example, with the Mediterranean and Central Asian phototype.- Lightsheer (or Gentleyag) will be the best choice. For dark brown and black skin of the African phototype, you need to choose Gentleyag.
Energy density shows how much energy comes per unit area (J/cm2). This is the main parameter that you need to look at when choosing a device for hair removal. The energy density should be distributed evenly over the entire surface of the working window and correspond to the issued. If the program has a value of 20 J/cm2, then the output should be the same meaning.
A high density indicator correlates with a more pronounced hair removal effect. But at the same time, the probability of the appearance of unwanted side effects is also higher.
The recommended exposure energy density is indicated on laser devices, but it is more intended for inexperienced operators. A more correct method for determining the optimal flow density for a particular patient is to evaluate the achievement of the required clinical result along the peripholicular erytema and edema.

Thus, the highest effect of the energy flow, which will be transferred to the patient, will show the best effect of exposure to the best effect. The clinical result should be without unpleasant effects.
The optimal working energy density will be a 20-40 J/cm2 indicator.
Another method of removing unwanted hairs by means of laser is the IPL technique. This type of laser hair removal provides exposure to follicles through high.Intensity light beam. Its wavelength is adjustable (it changes from 500 to 1200 nm). The IPL apparatus is able to interact with melanin in the skin when settings for a low wavelength. It rarely provokes burns, the intensity of the beam is tuned on the basis of data on the skin of the client and the condition of the hairs, but can cause undesirable pigmentation if the skin is located to this.
- High efficiency in removing hair of all types.
- A tired beam allows you to use a device for all skin and hair types.
- The high price of one procedure, the number of processing and duration determines the setting of the laser.
Lasers for hair removal of the IPL type have proven themselves in medicine. They treat individual skin diseases, in t.H. Age.Related, hyperpigmentation and solar pigmentation. The pulsating length of the light beam affects hemoglobin in the body, which makes the device with medical. These devices are attributed to expensive equipment. They can be allowed to be specialized medical centers and rare cosmetic salons.
Candela Gentlelase Pro-U
“Before the Candela Gentlelase Pro-U laser hair removal procedure, it is not necessary to wrap your hair: it will burn out during the session,” says Julia Chebotareva, head doctor of the Estelab aesthetic medicine clinic. “The subcutaneous part of the hair, which is located in the dermis, does not burn and is pushed out with the onion with the onion for several days”. Repeat epilation is recommended after one to two months, depending on the field of exposure. On average, six to seven sessions are required. The darker the hair, the better it is removed. In addition to high efficiency, Candela Gentlelase Pro-U is loved that it is equipped with a dynamic cooling system (DCD), which practically eliminates pain during the procedure. Before a laser pulse and after it, a small dose of cryogen is sprayed onto the skin, cooling it to the optimum temperature. “The most commonly used diameter of the working spot on this device is 18 millimeters, which allows you to quickly carry out the procedure. The Alexander’s laser is not suitable for patients above the fourth phototype of the skin and is not used after tanning, because the melanin of the skin can, like hair, become a target for a laser beam, which increases the likelihood of burn reactions, ”warns Julia Chebotareva.
