How does laser hair removal work?
The epilator targets hair follicles with a laser beam. It burns the hair root, causing it to fall out after a few days. The device recognizes hair due to the difference between its color and skin color. It is not possible to completely get rid of hair using a laser, since the epilator recognizes and burns hairs at a certain stage of development due to different wavelengths of the light pulse.
If the hair is in the early stages of development, it will not be possible to remove it. Therefore, to get absolutely smooth skin, you need to prepare for several sessions. Some types of hair cannot be removed at all using this method. The device is effective only when the hair color contrasts with the skin color. Maximum results can be achieved only when the hair is dark and the skin is light. If the hair is light or too thin, in the form of a fluff, it will not be possible to get rid of it using a laser.

Types of lasers
There are several types of lasers used for hair removal, but the preparation for each is almost the same.
- The very first laser to appear was a ruby laser , wavelength 694 nm, now used a little less frequently. Despite the advantages, it also has limitations - it requires light skin and dark hair. If you have even a light tan or light hair, it is not very effective. Often requires a large number of sessions for the same area.
- Alexandrite laser is already more advanced compared to the previous one, wavelength 700-820 nm. Due to the more powerful radiation, it penetrates better even through dark skin and requires fewer treatments. However, the hairs should still be dark.
And newer, modern varieties that are gaining popularity:
- Diode laser - the wavelength of this laser is from 800 to 980 nm, so the beam is able to penetrate even dark-colored skin and effectively destroy hair follicles. Its peculiarity is the relatively low speed of hair removal.
- Neodymium laser - wavelength - 1064 nm, has the highest penetrating ability and power, effective for any skin and hair color.

Types of laser hair removal
You won’t be able to spontaneously go to the salon and get laser hair removal; it is important to go through a long preparation stage, which usually takes more than one week.
Important! You should start preparing only after visiting a salon, where a cosmetologist will determine your skin and hair type, point out contraindications and draw up a list of recommendations.
How to prepare for laser hair removal most competently depends on the period before the procedure.
6 weeks before laser hair removal
The healthier the hair, the easier it is to remove it with a laser. Therefore, you need to stop using any products that affect the root, as well as bleaching agents, for a month and a half.
In 4 weeks
Before visiting the salon, you should avoid tanning the treated areas for a month. Even the slightest tan negatively affects the effectiveness of the procedure. The sun's rays make the skin darker and the hair lighter, which causes the necessary contrast to be lost. Because of this, summer is considered the worst period for laser hair removal. It is better to visit the salon in the autumn-winter period. Naturally, you should also avoid using a solarium. Exposing tanned skin to a laser can cause burns.
One month before the procedure, you should stop tanning.
In 2-3 weeks
At this time, you should not carry out any cosmetic procedures related to hair removal. If the hair is removed but the bulb remains, the laser device will not be able to recognize it. Only a razor can be used.
In 2 weeks
For 2 weeks you need to give up various creams, lotions and self-tanners that change the tone of the epithelium. They, like natural tanning, negatively affect the results of hair removal.
In 1 week
Seven days before the procedure, you should avoid most cosmetic products. Most of the ingredients included in creams, lotions and scrubs have a destructive effect on the integrity of the skin and can cause irritation.
Be sure to exclude products that include vitamin A, salicylic acid and benzene peroxide. Moreover, they cannot be used not only before the procedure, but also for at least 7 days after hair removal. You should grow your hair to a length of several millimeters.
A week before the procedure, you should grow your hair up to three millimeters.
In 1 day
Before the laser hair removal procedure, you must shave your hair. This will have to be done in any case, so it is better to take care of this in advance. One day is enough for the skin to calm down after irritation.
Note! You should use high-quality shaving products that do not irritate the skin, as well as new razors, since previously used blades can introduce bacteria into the irritated area.
If you plan to perform hair removal at home using a portable epilator, you need to ensure that you have the necessary accessories (safety glasses, numbing cream and sedative for post-treatment). The use of safety glasses is mandatory, since the light pulse from the device can damage the retina of the eye. If the manufacturer has not included glasses in the kit, you should buy new ones. The glasses should fit tightly to the face so that there are no loose areas. In salons, safety glasses are mandatory.
A few hours before the procedure
On the day of the procedure, you need to wear clothes made from natural fabrics; preference should be given to loose-fitting ones. This is necessary so that the tissue does not irritate the skin after the procedure. You should also treat the desired area with a soothing cream.
After sleep, you should take a shower to thoroughly cleanse your skin; you should not use any moisturizers. Depending on the area being treated, be it the face, armpits or other areas, it is worth giving up cosmetics, deodorants and other cosmetics. You should avoid caffeine-containing drinks, as they increase sensitivity to pain.
You should avoid caffeinated drinks
1 hour before the procedure
It is recommended to take a painkiller tablet. This will help make the procedure easier. If you plan to epilate sensitive areas, it is better to take two tablets. Instead of tablets, you can use pain-relieving creams based on lidocaine, which should be applied 20 minutes before the procedure.
Disadvantages of the procedure
The laser hair removal technique, with all its many advantages, is not suitable for everyone.
- For example, there is no point in performing it on dark or very tanned skin, as well as on people with blond and gray hair.
- This method also involves a long period of procedures, the number varies individually, but usually you need to visit a cosmetologist at least 5 times, and more often 7-9 times. The time interval between procedures is 1.5-2 months. During this time, dormant hair follicles that were not affected by previous exposure “wake up.”
- Also, each procedure is quite time-consuming. The flashes hit a small area of skin. Therefore, to treat an area, for example, shins or bikini, you will need a lot of flashes. In total, each procedure, depending on the type of laser and equipment, will take at least 1-1.5 hours.
- Laser treatment of some sensitive areas may cause discomfort. This applies to the bikini area, armpits or face.
- This procedure is also expensive. And to completely remove hair even from one area, you will have to spend not only a lot of time, but also money.

Possible complications
- Burns to the epilation area occur when the skin is not cooled sufficiently during the procedure. This can happen when using outdated equipment or when a cosmetologist violates the hair removal technique. For prevention, it is necessary to additionally apply ice after the procedure.
- Scars or the growth of keloid tissue - occurs when a person has an individual tendency to increased growth of connective tissue.
- Folliculitis - inflammation of the hair follicles themselves - can occur in response to attempts to pull out burnt hairs or when visiting a bathhouse/sauna/swimming pool in the first days after the procedure. And also when playing active sports.
- A rash of herpetic blisters is how the body reacts to skin damage in some people. To prevent this, you need to take an antiviral drug the day before the procedure.
- Pigmentation disorders: (hypopigmentation of skin and hair - hairs may not fall out, but turn gray, light spots appear on the skin; skin hyperpigmentation - long-term darkening of the affected area, as with a strong tan)
- An allergic reaction at the site of exposure most often occurs due to the use of local anesthetics (Lidocaine).
- Conjunctivitis, eye damage with retinal detachment - can occur when removing facial hair without following safety precautions. The eyes should be covered with tight-fitting special glasses. The beam is not directed towards the eyes.
- Bruises, bruises, spider veins - occur when blood vessels are fragile or have a blood clotting disorder. If there is such a tendency, start taking Ascorutin a week before hair removal and finish a week after it.
