Methods of combating unwanted hair on the face and body are improved from year to year. Epilation with an alexandrite laser was a real breakthrough in cosmetology and was subsequently taken as the “gold standard”. The main difference of this type of exposure from all others is the possibility of generating light pulses with a speed of up to 30 m / s and an increased depth of penetration of the laser beam.
General Laser Information
Alexandrite laser got its name from the durable gemstone alexandrite (a type of chrysoberyl). In nature, it is rare and differs from other minerals in the ability to change color depending on the current lighting (from dark blue and green to purple or red). For the production of laser use artificially grown stones that are not inferior to natural in strength.
The development of a new laser has been carried out in the USA since the 1990 years, at first it was used for the needs of the military industry, then representatives of medicine and cosmetologists became interested in it. In 1997, the technology received approval from US national quality control and began to be used to remove unwanted hair. At the moment, the alexandrite laser has the following technical characteristics:
- light pulse length – 755 nm;
- possible spectrum of action – 700 – 820 nm;
- Speed of one flash – up to 3 m / s.
Indications for use
Alexandrite laser is used for hair removal, tattoo removal, pigment and vascular formations. Its use is also appropriate for the fight against benign neoplasms.
The effectiveness of the technique in removing unwanted hair is determined by observing the indications for it. So, alexandrite laser is suitable for eliminating thin dark hair growing on tanned or fair skin. If you focus on the table of skin phonotypes from Fitzpatrick, then it will be appropriate to carry out the procedure from 1 to 3 category, when working with the 4, 5 or 6 category, the efficiency decreases and the risk of complications increases.
Alexandrite laser hair removal is performed on the face (eyebrows, antennae, cheekbones) and on the body (armpits, chest, back, arms, bikini zone, legs and others).
The operation scheme of the alexandrite laser is indicated by the term selective photothermolysis. The laser acts only on the hair, without affecting the adjacent soft tissue. The light pulse is absorbed by melanin (the pigment responsible for color), is converted into thermal energy, heats and destroys the hair bulb. It dies at a temperature of 80 degrees, lower indicators only damage it, without interfering with the further growth of weakened hair.
Tanned skin, like dark hairs, contains a certain amount of melanin, therefore it also absorbs light impulses. When carrying out the procedure with such initial data, the risks of burns and damage to the surface layers of the dermis increase.
Alexandrite laser acts on the hairs in the stage of active growth, which is why it is realistic to remove no more than 30% of their total number in one procedure. To achieve the effect of absolutely smooth skin, a course of 4 – 10 sessions with a break from 5 to 8 weeks is required. Specific figures are determined by the cosmetologist for each patient individually. They depend on the hormonal background, the localization of the problem area and a number of other factors.
Preparation and conduct
Preparation for epilation with an alexandrite laser is carried out according to the classical scheme. For 2 weeks before the procedure, it is forbidden to sunbathe, and for 48 hours it is necessary to shave long hairs in the problem area (at the time of processing, they should not be more than 3 mm). For a day you should not use scrubs, makeup, drink alcohol.
The duration of the session depends on the size of the area with hairline. On average, it equals 1 – 1.5 hours. During this time, the cosmetologist performs the following actions:
- skin cleansing and disinfection;
- applying a cooling gel (if necessary, additional anesthesia);
- processing (hairs do not fall out immediately, but after 6 – 10 days);
- applying a calming composition.
The results obtained after completing the course are stored for 2 – 7 years.
Side effects and care recommendations
Subject to indications and contraindications to the procedure, complications after it are excluded. Within two days, side effects of a temporary nature can be observed, this is a slight reddening of the skin, soreness and swelling.
If the treatment of vegetation with an alexandrite laser was performed on a patient with dark skin, there is a risk of burns, blisters, severe swelling, and a change in pigmentation processes. In such cases, the cosmetologist or dermatologist prescribe a special additional treatment.
Skin restoration after the procedure lasts 10 – 14 days. The following recommendations should be followed throughout the rehabilitation period:
- Do not wet the treated area (24 – 36 hours).
- Reduce physical activity to prevent active perspiration.
- Refusal to visit the baths, saunas, swimming pools, beaches.
- Use of sunscreens before going outside.
In between sessions, the growing hairs do not epilate, but shave, the frequency of laser treatments is not violated (minimum break 1 month).
Restrictions on the use of alexandrite laser should not be violated. Neglect of contraindications leads to complications. So, the procedure is not recommended for:
- diabetes mellitus;
- the presence of malignant tumors;
- individual laser intolerance;
- fungal skin lesions, dermatological diseases, open wounds or inflammatory processes;
- exacerbation of chronic pathologies;
- elevated body temperature and general significant malaise.
If necessary, the list of contraindications can be expanded.

Popular types of laser systems
The method of using alexandrite laser is recreated in many devices. Most often, cosmetologists practice using the following systems:
- Candela GentleLASE. It has an integrated cooling system and a large diameter nozzle (up to 18 mm).
- DEKA, Synchro PLAY. A universal system that includes several types of laser radiation. It is used for the integrated provision of cosmetic services.
- ARION, Quantel Derma. Suitable for problem areas of considerable size, it works quickly and efficiently, there is air cooling for the skin.
Alexandrite Laser Hair Removal allows you to get rid of unwanted hair for up to 5 years. During the procedure, light pulses are absorbed by the colored pigment inside the hair, converted into thermal energy and destroy the core and hair follicle. The exposure is carried out on a course basis, since the laser beam is active exclusively in relation to the hair in the growth phase.
