Couperose : qu'est-ce que c'est? et pourquoi est-il mieux traité au laser?

Rosacea: what is it? and why is it best treated with laser?

Mar 01, 2024

In the field of aesthetic dermatology, the use of laser technology represents a major advance for the management of multiple skin conditions. Rosacea, a skin disorder that is both common and a source of complexes for those affected, finds in laser treatment an effective and gentle method to reduce its symptoms. This process, laser rosacea , which is based on the targeted use of laser light, offers a non-invasive alternative, making it possible to visibly reduce rosacea without requiring surgical intervention. This procedure can be performed by a cosmetic dermatologist and does not present any particular danger for the patient.

What is rosacea?

Rosacea is a dermatological condition that usually affects the face, more precisely the central part of the face. It is characterized by the appearance of fine red veins on the cheeks, nose, forehead and sometimes the chin. Although it is primarily a cosmetic problem, rosacea can also cause discomfort, such as itching or tightness.

This condition is caused by a dilation of small blood vessels beneath the surface of the skin. It can be triggered or exacerbated by several factors, including the sun, age, alcohol consumption, stress, extreme temperatures and certain foods. Over time, these blood vessels may become more and more visible; these changes give the skin a constant reddish appearance, sometimes accompanied by small bumps and pimples.

How laser treatment for rosacea works

Laser treatment for rosacea is a procedure that uses pulses of light to treat spider veins and facial redness. The laser penetrates the skin to the blood vessels, where the energy is absorbed by the color of the latter, causing their elimination without affecting the surrounding tissues. This process is also called selective photothermolysis.

Additionally, there are a variety of lasers available to treat rosacea, including the Nd:YAG laser and intense pulsed light (IPL) . The choice of laser will be determined by your dermatologist, taking into account your skin type and the condition of your rosacea.

Laser treatment sessions typically last between 15 and 30 minutes, depending on the size of the area being treated. It may be necessary to repeat the treatment every 4 to 6 weeks for best results. Post-treatment follow-up is also recommended to evaluate and maintain treatment effectiveness.

A slight burning sensation may be felt during treatment, but is generally well tolerated. A numbing cream may also be applied before treatment to reduce discomfort.

How does the laser act on blood vessels?

The light energy from the laser, when absorbed by the rosacea , resonates with the blood molecules in the burst vessels, causing their bursting and gradual disappearance. The laser device generates a beam of light that specifically targets hemoglobin, the substance that gives blood its red color.

Hemoglobin absorbs the laser light, causing a thermal reaction. This heat causes the affected blood vessels to clot, which are then removed through the body's natural healing process.

Laser treatment for rosacea is technologically advanced, but the underlying principle is simple: emit light energy precise enough to target only affected blood vessels, without damaging surrounding tissue. This precision ensures an advantageous safety profile and makes the treatment effective in visibly reducing rosacea.

Benefits of laser treatment for rosacea

Laser treatment for rosacea is selective. After precisely targeting diseased blood vessels, it destroys them to restore the skin's smooth and uniform appearance.

The precision of the laser is such that we often speak of “targeted treatment”. It is this precision that allows the rest of the skin to be spared, causing virtually no collateral damage.

The effectiveness of laser treatment for rosacea is supported by scientific studies. Most patients report a significant improvement in their symptoms after the first session and an almost complete disappearance of rosacea after several sessions.

The treatment is quick and causes little discomfort . A session lasts on average between 15 to 30 minutes, under local anesthesia. Side effects are usually mild and temporary, including mild redness and slight swelling of the skin.

Another major advantage is the sustainability of the results . This is because once problem blood vessels have been treated, they generally do not form again. Obviously, this largely depends on the course of the underlying disease.

Safety profile of laser treatment for rosacea

The safety profile of laser treatment for rosacea is a crucial point to consider. The good news is that this procedure is considered safe and very rarely associated with serious side effects. However, some people may experience slight redness or warmth in the treated area, which usually disappears shortly after treatment. In rare cases, temporary changes in pigmentation may occur.

Remember, the key to a successful intervention is choosing a qualified healthcare professional to administer the treatment. The training and experience of the practitioner are indeed decisive factors in minimizing risks and ensuring optimal results . It is always recommended to have a thorough discussion with your treating physician before deciding to pursue such treatment, in order to weigh together the potential benefits and possible risks based on your own medical situation. Keep in mind that each case is unique, and your doctor is there to guide you every step of the way .

Next steps and post-treatment care

After undergoing laser treatment for rosacea , the skin may experience a reaction similar to a sunburn. Often, redness or swelling will subside the day after treatment. However, in some cases these effects may last for up to two weeks.

It is recommended to avoid intense contact with the sun after laser treatment. In particular, it is best to wear sunscreen with a sun protection factor (SPF) of 30 or higher. This can prevent cuperosis from getting worse and help protect the skin as it heals.

Consumption of alcohol and spicy food should be avoided for a short period after treatment, as these factors can cause dilation of blood vessels and increase redness of the skin.

To clean your face after treatment, it is recommended to use gentle care products . You should also avoid rubbing or scratching the treated area. After a while, when flaking begins, a moisturizer can be used to help the skin heal.

Now that you have an overview of the care to be taken after laser treatment for cuperosis, it is necessary to follow these instructions carefully. This will not only maximize treatment results but also ensure safe and rapid healing and recovery.

Why choose laser treatment for rosacea?

It should be noted that laser treatment is recognized as one of the most effective methods for treating rosacea . It offers high precision to specifically target dilated blood vessels without affecting surrounding tissues. By eliminating these vessels, the laser reduces redness and the appearance of visible veins, significantly improving the appearance of your skin.

Unlike other treatments, this technique generally requires fewer sessions to obtain noticeable results. You will therefore save time and resources by opting for this type of treatment.

It is worth mentioning that laser treatment for rosacea is relatively painless. While some people may experience mild discomfort, most patients describe the sensation as a mild sting or heatstroke. In this regard, patient comfort is always a priority for healthcare professionals who perform these treatments, and many measures are taken to minimize discomfort.

For its precision, its effectiveness, the reduced number of sessions necessary and its low pain, the choice of laser treatment for rosacea seems to be an option to seriously consider. As with any medical treatment, it is advisable to speak with a healthcare professional who can help you make an informed decision by considering your specific needs and expectations.

Scientific studies supporting the effectiveness of laser for rosacea

Robust scientific studies support the effectiveness of laser treatment for rosacea . According to a report published in the Journal of Dermatological Treatment, 85% of patients showed significant improvement after a series of laser treatments. This success is due to the ability of lasers to specifically target the dilated blood vessels that cause rosacea, thereby minimizing damage to surrounding tissues.

Another study published in Dermatologic Surgery found that laser treatment is of great benefit to patients suffering from severe rosacea. Researchers found that the majority of patients reported a significant improvement in their appearance, with a marked reduction in redness and rashes. They also noted a better quality of life through increased confidence and self-esteem.

Each study has demonstrated that the laser has a superior ability to reduce redness and inflammation. It is important to note that all research suggests that the best results are achieved with multiple treatment sessions, not just one. The exact number of sessions needed will depend on the severity of the rosacea and the individual characteristics of each patient.

Future developments in laser treatment of rosacea

Looking to the future, we see that the potential of laser technology in the treatment of rosacea is only beginning to be realized. Continued scientific advances are leading to a growing interest in more effective and less invasive approaches to treating skin conditions similar to rosacea.

Recent studies suggest that new methods of laser application could further reduce redness and inflammation. These methods include the use of shorter pulse lasers, which more precisely target the blood vessels involved in rosacea. Additionally, next-generation lasers could potentially reduce the number of treatments needed, for increased efficiency and convenience.


Laser treatment for rosacea is an effective method, without scarring or prolonged recovery time. It is an advanced technology that delivers impressive results. It is essential to begin with an initial consultation with a qualified dermatologist to discuss your specific symptoms and treatment goals. Also remember to follow post-treatment instructions carefully to ensure the best possible results. So, rosacea can be treated safely and effectively using laser technology, allowing you to regain healthy-looking skin.
