Centre Laser Sorbonne : The Paris Laser Center ! - Only by Certified Doctors - Monday/Saturday



Laser Permanent Hair Removal

Practically everything has been written on the subject of laser hair removal, which remains one of the prime uses of esthetic laser treatment. It offers a quick, effective, allergy-free and relatively painless procedure that leaves no scar and does not damage the pores of the skin.

Although many institutes offer laser hair removal, it is important to remember that only doctors - in France - are authorized to use Class-4 lasers, which, because of their high power, are the only ones to combine safety and long-lasting results.

Other techniques can offer results for certain hair types, for example, flashlamp (IPL), but in this case as well, not all lamps are equal. A patient can easily lose his bearings, forgetting too often that the object is not only to eliminate the hair, but also to protect the skin!

Despite the wide range of hair-removal techniques by laser or flashlamp depending on hair and phototype, there is unfortunately no all-in-one laser for this task. This is why it is best to have access to a laser platform that is optimally versatile and well equipped.

Laser and flashlamp allow for modulated hair removal by diminishing hair density, acting on hairs on any part of the body.

Aside from the time and money it can save over the course of a patient’s life, laser is particularly well-adapted to ingrown hairs at the bikini line for women and in the shaving area for men.

Achieving Permanent Laser Hair Removal

The Centre Laser Sorbonne medical team will suggest an appointment with one of our doctors. During this free initial visit he or she will speak with you and perhaps give you a test to make sure that nothing stands in the way of your treatment. You will receive answers to any questions you may have on lasers.

Centre Laser Sorbonne Hair removalIn accordance with French law concerning medical-class lasers, the doctor will give you an estimate with an informed consent form.

This estimate will specify the number of sessions, a schedule, the price of each session and the equipment to be used.

At the Centre Laser Sorbonne we have several hair-removal lasers, as well as a flashlamp, allowing us to find the best solution for each patient’s specific needs.

Three Alexandrite lasers, APOGEE 9300 (Cynosure), together with a powerful cooling system, CRIOJET 600.

The Cynosure Nd:Yag LP - ACCLAIM, used specifically on darker phototypes.

Finally, as a medium-term solution for some areas that may not respond optimally to conventional lasers or younger patients (for example, down on the upper lip), the Centre owns the new Q-Switched Nd:YAG REVLITE laser (HOYA ConBio).

Laser Hair Removal Procedure

The length of the session varies, as it depends on the size of the area to be treated. It may last anywhere from ten minutes to an hour and a half for a single area.

The spacing between sessions becomes progressively longer during treatment. The number of sessions also varies, depending on the area treated and also on the patient. Your doctor will provide more-specific information when he or she gives you your personalized estimate at your first visit.

The area to be treated must be carefully shaved before the session so that the hair tip is just above skin level (1 mm maximum). Waxing may be performed not less than eight days before the laser session. However, it is recommended that temporary hair removal be avoided before your initial consultation so that the doctor may be able to determine the appropriate treatment and parameters.

The doctor sweeps the area carefully, using an appropriate handpiece or a scanner. The epidermis is cooled by a gel applied beforehand or by cold air during the treatment. The session is not particularly painful, aside from heat and a momentary pricking sensation.

During the session the follicles in the anagen (active growth) phase will be destroyed. Those in the dormant phase need to be targeted later, when they resume active growth. A series of sessions is therefore necessary to eliminate all the hairs. The number of sessions and their length depend on the size of the area treated and the hair-growth cycle of that area. As an indication, however, for the great majority of cases, satisfactory results are achieved in five to six sessions scheduled over the course of a little more than a year. The doctor of the Centre may eventually recommend a thermolysis session for any stubborn hairs that might remain.

Potential Laser Hair Removal Counter-Indications

The principle of laser hair removal is simple. The beam sweeps the area to be treated. The wavelength is selected to target melanin, the color pigment of the hair. The dark hairs absorb the rays, which destroy the bulb and the bulge.

This brief explanation allows us to specify the limits of laser action and potential counter-indications.

When a hair is poor in melanin (white or bleached hairs, for example), the laser has no effect.

On the other hand, when the skin is tanned by the sun or UV treatment, laser is counter-indicated, as the melanin in the skin, rather than the bulb, would become the laser’s target.

With darker complexions, certain precautions need to be taken.

The use of medications that affect the photosensitivity of the skin may also counter-indicate treatment.

Finally, pregnancy constitutes a counter-indication as a matter of principle, as is the case for all laser treatments.

After your Laser Depilation Session …

An erythema (redness) and a light edema (swelling) appear in a few minutes and disappear within hours. Tiny scabs may form at the base of the hairs; they will disappear a few days later.

A hydrating cream is applied at the end of the session. The skin must not be exposed to the sun for a month after any session.

The Cost of Laser Hair Removal

The price is determined by the size of the area to be treated and therefore the length of each session. The treatment of several areas in the same session allows for a price reduction.
