Types of lasers and their safety
The principle of laser hair removal is to remove hair due to the destruction of hair follicles. The pigment melanin contained in the hair shaft and bulb is capable of absorbing light radiation in the range 700-800 nm. This leads to its strong heating and destruction of the cells around it, responsible for hair growth, and feeding the hair follicle of the vessels. The laser radiation penetrates under the skin to a depth of 5 mm and affects only the hair in the active growth phase, so a complete course of several sessions is required to completely remove them at a certain site.
To combat unnecessary hair, different types of lasers are used, differing in wavelength (the bigger it is, the deeper the ray penetrates):
- Ruby. It is characterized by a wavelength of 694 nm, a pulse duration of 3 ms, a frequency of 1 Hz, a power of 40-60 J / cm2. Suitable for dark hair on light skin. When used on dark skin, swelling and the appearance of pigmentation are possible.
- Alexandrite. Generates radiation with a wavelength of 755 nm, pulse duration 2.5-20 ms, repetition rate 1.5 Hz, power 20-40 J / cm2. The darker the color of hair removed, the more effective. Not suitable for gray and very light hair. Can be used on lightly tanned skin.
- Diode (semiconductor). It emits radiation with a wavelength of about 800 nm, a pulse duration of 5-30 ms, a frequency of 2 Hz, a power of 10-100 J / cm2. Can remove blond hair on dark and tanned skin. Affects not only the melanin, but also the vessels surrounding the hair follicle.
- Neodymium. Generates radiation with a wavelength of 1064 nm, a pulse duration of 100 ms, a power of 2-3 J / cm2. It is almost not absorbed by melanin, but it affects the vessels that feed the hair follicle, which subsequently leads to the death and hair loss. Suitable for any shade of hair and skin type.
Ruby laser hair removal for today is practically not used, which is connected with its low efficiency, high risk of getting burns and the appearance of modern instruments that give better results and are more safe. "Golden standard" to date, according to many cosmeticians, is a diode laser.
Important: Before performing laser hair removal, you need to consult a dermatologist and a cosmetologist. They will find out whether it is possible to do it, and will select the optimal radiation for the exposure, depending on the skin type, thickness and color of the hair, which you need to get rid of.
To get rid of unwanted hair on the body by laser hair removal, there are general and local contraindications. The first include diseases that occur in a chronic or acute form, in which the effect of laser radiation in any zone is undesirable, since it can provoke a deterioration in health and cause harm. Among them:
- pathology of the skin (eczema, psoriasis, lupus erythematosus, dermatosis and others);
- diabetes mellitus in the stage of decompensation with high blood glucose levels;
- oncological diseases;
- herpesvirus infection;
- angina, influenza, respiratory infections (epilation is not done until full recovery);
- skin allergic reactions;
- mental disorders;
- serious hormonal disorders;
- pathology of the cardiovascular and circulatory system, taking place in severe form;
- the tendency of the skin to form keloid scars;
- taking antibiotics (the procedure is contraindicated during and for two weeks after taking the course of treatment), as they increase the photosensitivity of the skin and can trigger burns.
In addition, the laser hair removal can not be done after sunbathing, regardless of whether it was obtained in the sun or in a solarium, and also within a month after chemical peeling or laser skin resurfacing. If these items are ignored, the risk of severe burns to the skin and other negative consequences (dryness, irritation, peeling) is significantly increased.
The use of laser hair removal is not recommended for people whose age is less than 18 years, which is due to instability and restructuring of the hormonal background, the active formation of secondary sexual characteristics. Although in some cases after receiving the written permission of the parents of this category of clients, hair removal is still carried out.
For blondes or people with gray hair, the procedure (with the exception of neodymium laser) will be ineffective and useless in view of the lack or too low content of melanin in them. As a result, the client is wasting money and will expose his skin to in vain irradiation.
Important: To prevent a part of the complications, at first the expert must check the reaction of the client's skin to radiation in a small area. Some may have an individual intolerance or hypersensitivity to this kind of effect on the skin.
Local are contraindications that do not allow laser hair removal only in certain areas of the body if they have any problems, for example:
- inflammatory processes;
- presence of moles and papillomas;
- violation of the integrity of the skin (cuts, burns, abrasions, wounds, scratches);
- acne, acne;
- pigmented spots or tattoos.
Perform laser hair removal on the legs or in the bikini area is contraindicated if there is varicose veins of the lower extremities or small pelvis. In the bikini zone, it can also not be performed with any inflammatory diseases of the pelvic organs (sex infections, candidiasis, thrush, etc.), the skin here is very tender and sensitive, so it requires special care, it easily forms micro-trauma.
Hair removal by this method in the area of the armpits can not be performed in any mammary gland diseases. When removing facial hair ("antennae"), it should be borne in mind that darker areas may leave areas with a lighter shade, pigment spots, burns and bruises appear.
Application in pregnancy and lactation
Doing laser hair removal in women during childbearing and breastfeeding is strongly discouraged. In pregnancy, it can cause more intense pain than usual, and provoke an increase in the tone of the uterus, which affects both the fetus and the expectant mother. During this period, as well as breastfeeding, a hormonal adjustment takes place in the female body, aimed at creating all the conditions for the bearing and birth of a healthy baby. In addition, it is possible to reduce immunity and exacerbation of chronic diseases.
All these factors affect the increase in the susceptibility of a woman's skin to the action of laser radiation and cause a number of complications. The skin of a woman during pregnancy is more prone to hyperpigmentation, and the use of a laser in this case is capable of provoking it.
A pregnant woman should first of all think about the health of the future baby, and beauty can be done after his birth. Given that the long-term effects of the procedure are not yet fully known due to a not very long use in cosmetology practice, putting such experiments on themselves and the unborn child is an unjustifiable risk.

Effects of epilation
When performing epilation with the help of laser radiation in spite of the existing contraindications, its consequences can be unpredictable. Complications most often occur if the procedure is made by an unskilled specialist who does not have sufficient practical experience in this area, which incorrectly establishes the mode of operation of the device and does not observe safety procedures. Also, the risk of their occurrence increases significantly if the client does not adhere to certain limitations before and after the session.
Possible negative consequences include:
- inflammation of hair bulbs;
- Hyperpigmentation of the skin in the treated area;
- redness of the skin or burns;
- allergic reactions;
- swelling and bruising;
- burning and itching of the skin;
- eye damage;
- the formation of scars at the site of laser action;
- peeling and dryness of the skin;
- degeneration of birthmarks into malignant formations;
- hormonal failure .
Minor reddening and puffiness of the skin after the procedure is a completely normal reaction, not requiring special treatment. To reduce them, use a local ointment or cream, which should be prescribed by a dermatologist or a cosmetologist.
Despite the fact that many cosmetic salons and clinics laser hair removal is advertised as an absolutely harmless method, it should be understood that the long-term consequences (after 10 and 20 years) of its application are not yet fully understood and known.
Tip: Laser epilation is recommended in specialized cosmetology clinics, whose employees have all the necessary certificates and licenses to perform this procedure.
Laser hair removal at home
Recently, a number of portable devices have appeared on the market of cosmetology products, which make it possible to perform laser hair removal at home. From an economic point of view, the acquisition of such a tool seems to be quite profitable compared to the repeated visits to the salons necessary to get rid of all unwanted hair on the body. However, not all so simple.
As a rule, these devices are less effective, characterized by low power and only affect dark hair on light skin. In order to learn them and carry out the procedure on their own, it will take quite a lot of time, effort and patience. In the absence of experience, knowledge and skills, there is a high risk of self-harm and the complications described above.
