Laser hair removal

Laser hair removal is not for everyone

body laser hair removal tunisia price cheap priceHaving darker hair than the skin it is on. Highly pigmented skin (dark, black) will absorb too much laser energy into their skin (instead of seeing it absorbed by the hair) and are therefore not good candidates for laser hair removal.

Laser hair removal is an aesthetic medical procedure


On average, tattoos done by professional taxidermists require 6 to 10 sessions. Tattoos made by amateurs require only 3 to 5 sessions. It's a matter of type and amount of ink and depth of inclusion. The sessions are spaced out every four weeks. During your laser hair removal session, the device must be handled by a laser doctor. Setting up the laser is a fundamental step in the medical act. This must be carried out by a competent doctor, trained in the use of lasers, holder of a university degree in laser medicine. This diploma should be displayed in the laser center. If a laser technician performs the session, make sure that the setting of the device is done by a doctor: it is a guarantee of seriousness, respect and safety.

The color of the skin and hair has an influence on laser hair removal

Light skin makes laser hair removal easier. The number of sessions required is often lower, the results are often better and faster to obtain. Dark-skinned individuals can also consider a laser hair removal program, but the number of sessions will undoubtedly be greater, the results more difficult to obtain and will have to go to an experienced laser specialist. Each patient requires special attention. Dark hair absorbs more laser energy than light hair. Thick hairs are easier to destroy than fine hairs. Blonde (very yellow) and red (true) hairs are difficult to treat. Many sessions are required. Blond and red hairs contain pheomelanin which absorbs little laser energy, while dark hairs contain eumelanin, the ideal target for laser hair removal.

Laser hair removal requires several sessions

Although the first session already produces lasting results, a simple rule that follows the hair cycle is that, to be effective, the hair must "take" the hair during the growth phase, called anagen. All our hairs are not at the same time in the same phase. It is therefore necessary to repeat the sessions until all the hair in the area to be depilated is destroyed.

Laser hair removal can be performed on any part of the body, except the eye

Eyes and laser beam don't mix. It is therefore ALWAYS necessary to protect your eyes during a laser session. Your doctor will lend you a pair of special glasses or "goggles" (shells) to protect you against intrusion of laser light into the eyeball. The areas most frequently depilated with laser are: the face, the temples , upper lip, armpits, bikini area, neck, areolas of breasts, back, legs and umbilical line.

Laser hair removal is very long-lasting, even permanent

Wax, shave, cream, and tweezers are all just short-lived hair removal methods. The FDA and European health authorities have issued marketing authorizations for new lasers for the “permanent hair removal” indication. New clinical studies are published frequently on this subject. However, depending on the parameters used by your operator, the result will be either long-lasting hair removal or permanent hair removal. It appears in the most recent studies that only parameters considered to be advanced can achieve permanent hair removal. In this last approach, the cooling of the skin and the pain tolerance threshold are two often insurmountable obstacles in most laser centers. The cooling of the skin must be particularly studied. Therefore a special cooling unit must accompany the laser and be available for each pulse. The ideal is a “frozen” cold air system, in sub-zero, pulsed, on the area to be depilated. Thus, before each impulse the skin has time to cool and then be kept cold during each impulse and throughout the session. The pain tolerance threshold depends on each patient. Insofar as an act with an aesthetic aim is badly accepted if it hurts, the laser operator tends not to push his laser so as not to hurt. The problem is that the more efficient the beam is on the hair, the more painful it is. Finally, the results of each session tend to be cumulative: the more sessions you follow, the better the result and the more permanent the hair removal. However, each patient is different so the results are neither predictable nor predictable. They are variable, even with the best lasers.

Intense Pulsed Light (IPL) and Laser are not equivalent in hair removal

The physical or technological principle of each device is different. The laser sends a single wavelength light, therefore specific and coherent, the IPL emits in several wavelengths, therefore non-specific. Hair removal can be done with an IPL, yes, because it achieves the goal of photo-thermolysis of the hair, but the published results are not similar to laser. In addition, intense pulsed light is a little more complicated to use. , it requires great expertise on the part of the operator because the hair is not the only target reached by the pulsed light, the risk of error is therefore greater.

Tanning and laser hair removal don't mix

Tanned skin will burn with the laser. You have to know it and say it loud and clear. As we all end up detanning, you have to be patient and wait until the skin has become clear again to go see your laser doctor. Those who claim to treat tanned skin take serious risks, but do not say that they lower the parameters of the laser. For you, the result will be mediocre, it will take many sessions to do a good depilation, and in this case, it is more the wallet than the skin that will have been depilated.

Can we talk about permanent hair removal or not?

In the current state of knowledge and with the hindsight that medical teams now have on this type of treatment, we can now confirm the non-regrowth of treated hair. The difficulty lies in the complete nature of the treatment, due to the persistence in some patients with few hairs including white hairs, fine and light hairs.

Can we talk about definitive treatment of vascular and pigmentary lesions with laser?

Even if the results of laser treatment are generally excellent on this type of lesion, it is obvious that certain factors - such as exposure to the sun - increase the risk of new spots or lesions developing. Practitioners at the Center will therefore advise you to remain attentive to the evolution of the tissue and to reconnect with your laser practitioner if necessary. .

Are there any precautions to take?

 The diet does not interfere with the laser treatment, except beta-carotene: suspend it 2 months before a hair removal program.
 Children and teenagers can successfully complete a laser hair removal program. However, be aware that regrowth will occur when growth is not complete. The effects of laser on skin tissue in children have not been described in the literature. Finally, as the teenager generally cooperates well with the operator, so much the child under 12 can fear the process. It is best to reserve this procedure for individuals who really want it. Parental authorization is required, an estimate and consent must be signed by the patient and his legal guardian. It is important to accompany the minor during the session.
 Black skin individuals can follow a laser hair removal program with an Nd YAG type laser. The treatment will be longer (smaller spot size on this type of laser) but only this type of laser can obtain good results. These lasers are widely used in the African-American population in the United States.
 Who should avoid the laser: those who have just sunburned or tanned. Blondes, redheads with a recent tan. Those who cannot afford the cost of multiple sessions (5 to 8 on average).
