Frequently Asked Questions

The medical team of the Centre Laser Sorbonne will give you an appointment with one of our doctors. During this initial free visit, the doctor will speak with you and give you a physical examination to make sure there is no medical obstacle to treatment. He or she will answer any questions you may have on lasers.
The doctor will give you an estimate with an informed consent form in accordance to French legislation concerning medical lasers. The estimate will specify the number and scheduling of the planned sessions, the price of each session and the equipment to be used.

No, such a test is not mandatory. However, the doctor may suggest one during your initial visit depending on your skin and the treatment planned. It will be performed free of charge.

The Centre Laser Sorbonne is a versatile treatment centre offering dermatological, vascular and esthetic care. The number of sessions necessary to obtain the desired results depends on the type of treatment and the reaction of each patient, as well as the parameters determined by the doctor based on your skin and the power of the equipment. This is why it is indispensable to turn to highly experienced practitioners using rigorously maintained equipment.
For hair removal, an average of five or six sessions is generally needed to obtain long-lasting satisfactory results. Most usually, the second session is scheduled one month after the first, and the third session two months later; further treatment is scheduled only in the case of new hair growth.
In the case of vascular lesions, couperose shows a clear improvement generally in two or three sessions scheduled one month apart. Pigmented and cutaneous spots on the back of the hands are generally treated in one or two sessions.
As for laser treatments intended for the improvement of the complexion ("photorejuvenation") and skin tone ("remodelling"), four sessions spaced one month apart are usually necessary.

Given the present state of knowledge and the experience of medical teams in this type of treatment, it is now possible to confirm that hairs treated by laser do not grow back. The difficulty resides in the completeness of the treatment. Certain patients may have persistent hairs which can be eliminated by thermolysis.

Even if the results of laser treatment are generally excellent for this type of lesion, it is clear that certain factors, such as sun exposure, increase the risk of developing new spots or lesions. The practitioners of the Centre will therefore advise you to pay attention to changes in your skin tissue and to recontact them if necessary.

Our doctors' experience shows that laser treatment yields favorable results for the tone and elasticity of the skin (what some call "remodelling") and on the glow of the skin ("photorejuvenation") as long as the patient makes an appointment for an annual maintenance session.
The Centre Laser Sorbonne offers a unique combination of these two techniques - flashlamp (IPL) for photorejuvenation and remodelling laser - in order to achieve results in the short term (glow of the skin) and in the medium term (tone and elasticity).

It is the only place where you will find all the best conditions to obtain quality results: a medical team skilled in laser technology, accustomed to performing these procedures and able to offer you follow-up care when necessary.
A diversified technical platform, perfectly maintained by the builders, ensures your safety and the effectiveness of the care offered.

Unfortunately there is no "all-in-one" laser allowing for the whole range of treatments offered by the Centre Laser Sorbonne with effective results and optimal safety. The Centre offers only new equipment under maintenance contract to ensure your safety and give you the best results with a minimal number of sessions.

Several categories of equipment are available on the market. But only Class-4 lasers, reserved for doctors, ensure long-lasting results. There is an analogous classification for flashlamps (IPL).
By choosing to be treated at the Centre Laser Sorbonne you are assured of having doctors specialized in vascular and dermatological laser technology, who have at their disposal a whole range of equipment that is new, well maintained and thoroughly tested by them.

The effective lasers available on the market are powerful and may be dangerous if non-specialists operate them or set the parameters.

The more complete your doctor's mastery of the equipment, the less the chance of side effects. In any case they are limited and usually reversible. This is why you should follow the advice that your future doctor gives you during your initial free session at the Centre.
It is always possible to receive slight burns on the surface of the skin in the form of light scabs. These may appear 48 hours after the session and will disappear without a trace within two weeks. More rarely, reactions involving hyper- or hypo-pigmentation may be observed on the area treated. These are also reversible. However, it is important to distinguish normal effects of treatment from side effects. It is normal to experience skin redness and a hot sensation on the area treated, both of which disappear in a few hours. In addition, cooling techniques make it possible to considerably reduce these temporary effects. Laser treatment is generally performed in conjunction with a cooling of the epidermis.

In general, patients are strictly advised not to expose areas to be treated to the sun and, a fortiori, not to undergo UV treatment. Depending on how tanned your skin is, the doctor will determine with you the date when your treatment may begin upon your first appointment. Likewise, the recent use of self-tanning products or suntan activators is incompatible with undertaking treatment.

Yes, this is possible. But you must bring a letter of permission from your parents to your first appointment.

Although no studies are available, as an obvious legal precaution your doctor will advise you not to undergo laser treatment during pregnancy.

Make a point of mentioning to the doctor any medical problems that you may be subject to. Precautions should be taken if you are epileptic or diabetic, or if you have immunosuppressive or hormonal problems or a condition affecting blood coagulation, skin healing (keloids) or porphyria cutanea. These conditions do not necessarily present an obstacle to your being treated, but your doctor will need to discuss them with you.
Finally, certain local conditions may prove to be a temporary or permanent impediment to treating an area of your body, for example, herpes, beauty spots or wounds.
At your first appointment it is important to tell the doctor about any medications you may be taking, as some may be photosensitive.

Beyond the various cosmetic products with which you are familiar, such as fruit acids, the technology now available enables the Centre Laser Sorbonne to offer a remarkable and rapid improvement in the tone and glow of the skin. This includes the flashlamp (IPL) and remodelling laser. By allying these two techniques it is possible to act upon the uppermost layer of the epidermis and also on the dermis, to stimulate the natural production of collagen.

In France, laser treatment is still seldom used for spider veins. At your first appointment at the Centre the doctor may recommend a more in-depth vascular examination before beginning treatment to avoid any risk presented by underlying venous insufficiency.

The darker the hair and the lighter the skin, the better the results of laser treatment. However, the Centre is also equipped with a flashlamp (IPL) and a special laser for dark skins. At your first appointment the doctor will explain to you the results that you can expect, depending on the nature of your skin and hair.

The price of a session depends on the size of the surface treated, which explains why the price is slightly higher for men in the case of certain treatments, for example, hair removal.
