Is laser hair removal harmful to health?
No, laser hair removal is not harmful to your health. The premise is:
it is performed under proper instruction
after medical examination
Perfect control of the laser unit
Medical lasers are class IV and should only be used in medical offices. They are intense light sources, emitted at the same wavelength and in one direction, with the purpose of delivering enough energy to damage the hair. It is similar to the red or infrared light emitted by a kitchen grill. The wavelengths used are not mutagenic or carcinogenic. There is no radiation that could cause skin risks.
The laser targets melanin, the hair pigment, which absorbs the light and transforms it into heat. One of the dangers of laser hair removal is collateral damage such as burns or skin pigmentation problems if the recommendations and contraindications are not respected.
Indeed, melanin, present in hair, is also the pigment responsible for tanning. Therefore, if the laser treatment is performed on tanned or dark skin, part of the light energy will be diverted and may cause burns or skin pigmentation disorders (hypopigmentation or hyperpigmentation). It is therefore important to respect the time of non-exposure before the laser session and to adjust the type of laser according to the dark skin.
In addition, it is important that the laser be connected to the skin cooling system to reduce the risk of burns. Indeed, some of the energy delivered to the hair is diffused on the skin. Therefore, it helps maintain a low temperature by actively cooling the skin. The technology also provides pain relief and improves patient comfort.
