What is laser hair removal?
Laser hair removal is one of the so-called “permanent hair removal” techniques, as are pulsed light hair removal and electrical hair removal (electrolysis). The laser, which stands for “ Light Amplification by Stimulated Emission of Radiation” , is a light source with a single wavelength.
This light (energy) is specially adapted so that the melanin present in the hair bulb (black pigment, responsible for the coloring of the skin and hair) absorbs it. This has the effect of heating the hair and destroying the bulb, which will therefore no longer be able to produce new hair afterwards. This is called selective photothermolysis.
How effective is laser hair removal?
This hair removal method is mainly effective on people who have brown or dark blond hair (which therefore contains a lot of melanin) and white skin, due to the high contrast in color between the hair and the skin. However, there are certain lasers which, thanks to an adapted wavelength, allow hair removal on darker skin where the contrast is less pronounced.
It is necessary to carry out several sessions so that all the hairs in the same area are destroyed (5 to 12 sessions). Then, to judge the long-term effectiveness of laser hair removal, it is generally advisable to wait for the duration of a hair cycle (around 18 months).
Is laser hair removal painful?
If the various hair removal sessions are carried out normally and are supervised by a specialist doctor, they are generally not very painful. They can cause some tingling and slight burning sensations at the time and the appearance of scabs and edema afterwards, but which should disappear within a few days.
What are the dangers of laser hair removal?
The main danger of laser hair removal is the risk of burns , which can happen instantly after application or in the hours following. Some burns can reach the 3rd degree and are therefore very dangerous for health. These burns can be caused by too long a laser application time on the same area, by too high a power or linked to the characteristics of the patient’s skin. In addition, if the laser aim is not aimed sufficiently at the hair, it can destroy the melanin in the surrounding skin.
There are also risks which can be collateral. This is because if the laser is not handled properly, its light can reach very sensitive areas of the body such as the eyes, which would cause irreversible damage.
How to act in prevention?
Before the session
First of all, you should know that only doctors are authorized to use this permanent hair removal cream for men in india, so find out about the practitioner who will perform these hair removal sessions (dermatologist or general practitioner most often). Sessions performed by untrained personnel may cause side effects such as permanent scarring.
It is advisable to meet the doctor responsible for the intervention during a first consultation in order to be able to detect any contraindication (pregnant women, diabetics, patients undergoing acne treatment, by radio, chemotherapy, etc.)
It is also best not to expose yourself to the sun (UV) for about two weeks before the first session. Finally, the area to be depilated must be shaved 2 or 3 days before the session in order to allow an optimal pointing of the laser on the hairs to be destroyed.
During the session
In order to avoid or reduce feelings of discomfort during the operation, the doctor may, during the first consultation, prescribe an anesthetic cream to soothe the targeted areas. It should also provide you with glasses or a protective system to protect your eyes from the laser.

Laser hair removal: Its evolution, guarantee of its effectiveness
The first laser hair removal solution took its first steps in 1995. It is indeed following numerous experiments carried out by Dr. Goldstein that the first laser hair removal method was marketed.
Since then, research and innovations have continued to develop this hair removal solution. As a result, lasers with proven performance have been commercialized on the market. In addition to their effectiveness, the technologies used to date respect all skin types.
Indeed, laser hair removal sessions performed by specialists are a guarantee of quality, efficiency and flexibility.
Laser hair removal is now available to both men and women and can eradicate between 80% and 95% of the hair in the treated area.
Areas suitable for laser hair removal:
Laser hair removal allows hair removal on almost all parts of the body and face.
Indeed, the laser hair removal method is based on a simple principle, the sending of a laser wave which aims to create a thermo-coagulation which will destroy the lower 2/3 of the hair follicle.
This type of solution is effective on the majority of body hair, and on all skin types. However, some hairs are not receptive to the laser wave such as white hairs and red hairs.
Areas of hair removal in women:
