What is an aesthetic laser ?

The word laser is an acronym for Light Amplification by Stimulated Emission of Radiation. In medical practice, a laser is a very specific light source, capable of emitting monochromatic, coherent and directional light. These characteristics make it possible to deliver precise, controlled and reproducible energy to a given target.

How does a laser work ?

The fundamental principle is based on selective photothermolysis. This means that the laser’s light energy is preferentially absorbed by a target structure called a chromophore, without damaging the surrounding tissues. The three chromophores are melanin (the skin pigment), hemoglobin (therefore blood) and water. Depending on the chosen wavelength, the laser will interact with one or another of these elements, producing a localized thermal effect.
This selectivity is the key to the effectiveness and safety of laser treatments. It makes it possible to act on a precise skin abnormality while preserving adjacent structures, provided that the diagnosis, parameters and indication are perfectly mastered.

Dermatological and aesthetic lasers

Laser beams pass through the skin without damaging it to reach a precise target where a therapeutic effect will occur. Lasers have extraordinary therapeutic qualities, even though it is always necessary to remain cautious in terms of expected results.
Lasers are used in different medical specialties : ophthalmology, ENT, gynecology, gastroenterology.

Lasers in aesthetic medicine

There are many lasers, and each aesthetic or dermatological laser has a different treatment target and therefore its own indication.
Lasers are an unbeatable tool to combat the signs of aging. They have several fields of application : wrinkle treatment, skin densification, complexion uniformity, intimate indications.
The treatment must be performed by a physician. A prior medical consultation is carried out to allow proper patient selection, provide the necessary information and establish a personalized protocol.
Lasers and medical devices play an essential role in aesthetic-oriented medicine : they deliver remarkable results with short recovery times.

EMSculpt

EMSculpt is a revolutionary technology that uses focused electromagnetic waves to stimulate muscles and reduce fat simultaneously. By inducing intense muscle contractions, EMSculpt helps sculpt and tone the body, particularly areas such as the abdomen, the buttocks, the arms and the thighs. Patients can notice a significant improvement in muscle definition and fat reduction after just a few sessions.

Ablative laser

Ablative laser is a powerful method for skin resurfacing of the skin. It removes the superficial layers of the skin in order to stimulate skin regeneration and achieve smoother, younger-looking skin. This type of laser is ideal for treating acne scars, deep wrinkles, fine lines, signs of skin aging, skin laxity, pigmented spots and skin lesions. Results are often spectacular, although recovery time may be longer compared to other treatments.

Cryolipolysis

Cryolipolysis, CoolSculpting being the most well-known device, is a non-invasive technique that uses cold to destroy fat cells. Fat cells are more sensitive to cold than the surrounding tissues, which makes it possible to target them specifically without damaging the skin or muscles. Cryolipolysis is particularly effective for reducing bulges and fat deposits, notably at the level of the abdomen, flanks and thighs.

Hydrafacial

Hydrafacial is a multi-step skin care treatment that combines cleansing, exfoliation, extraction and hydration. Using patented vortex technology to cleanse pores and infuse hydrating serums, Hydrafacial delivers brighter and healthier-looking skin without causing social downtime. This treatment is suitable for all skin types and can help improve the appearance of wrinkles, fine lines, enlarged pores and dark spots.

Hollywood Spectra Laser

The Hollywood Spectra laser is a multifunctional device used for a variety of skin treatments. It is particularly well known for its use in gentle laser peels, which improve skin tone and radiance without exfoliation, therefore without downtime. This laser can also treat pigmented spots, acne scars and tattoos.

Vaginal Laser

Vaginal laser is a non-invasive solution for women suffering from various gynecological issues, such as vaginal dryness, stress urinary incontinence and vaginal laxity. This treatment stimulates collagen production and improves the quality of vaginal tissues, which can result in a significant improvement in comfort and quality of life.

Radiofrequency

Radiofrequency is a non-invasive technology that uses electromagnetic waves to heat the deeper layers of the skin. This heat stimulates the production of collagen and elastin, allowing skin tightening. It is particularly effective for treating skin laxity, wrinkles and stretch marks.

What is the difference between an ablative and a non-ablative laser ?

Understanding laser technologies is primarily based on the distinction between two main categories : ablative lasers and non-ablative lasers. These devices differ in their mode of action, their intensity and the post-treatment effects.
Ablative lasers act by controlled removal of the superficial and/or deep layers of the skin. This action triggers skin regeneration with complete renewal of the epidermis and intense stimulation of dermal synthesis. Carbon dioxide (CO₂) and erbium lasers belong to this category. By promoting significant collagen production, these technologies allow a lasting improvement in skin firmness and elasticity. In return, this type of treatment requires rigorous post-procedure care. The after-effects are significant but temporary : redness, swelling and oozing, as well as a longer period of social downtime.
Non-ablative lasers are based on a different approach. Their energy penetrates the skin without altering the skin surface. They produce a gradual and controlled heating of the tissues, at the level of the epidermis and especially the dermis, which stimulates collagen and elastin synthesis without destroying the skin. These treatments are considered less invasive and are generally associated with a shorter recovery time, often limited to a few days.
In order to further reduce social downtime, some technologies use fractional ablation. This technique consists in treating the skin in par-zones microscopiques while leaving healthy tissue between the treated areas, which accelerates skin repair while maintaining high effectiveness.

For what reasons can laser treatment be requested ?

Laser technologies now occupy a central place in the management of skin imperfections. They make it possible to treat numerous indications thanks to a targeted and controlled action on the different components of the skin. Each laser technology is based on a specific wavelength, selected according to the biological target to be treated : melanin, hemoglobin, or the water contained in the tissues. This precision makes it possible to adapt the treatment to each indication.
Pigmentary anomalies are among the most frequent reasons for consultation. Sun spots can be eliminated thanks to lasers specifically designed to target pigments. Certain post-inflammatory hyperpigmentations can also be improved. Melasma and freckles can likewise be reduced.
Vascular issues represent another major indication. Chronic facial redness, whether diffuse or linked to the presence of visible small vessels, can benefit from vascular laser treatment. In erythematotelangiectatic forms of rosacea, a notable reduction in erythema and visible vessels is frequently observed.
Lasers are also used as part of a skin rejuvenation approach. Their action is based on controlled stimulation of skin cells, which promotes dermal renewal and collagen production. This progressive approach helps improve skin quality, firmness and radiance.
Certain scars, particularly those related to acne or surgical procedures, can also be treated with appropriate lasers. Effectiveness depends on several factors, including the type of scar, its age and the individual patient’s response.

How does a laser session work ?

A laser treatment is carried out exclusively within a medical practice, in a medical environment and by a physician. Before any management, a prior medical consultation is systematically organized. During this appointment, the physician carries out an in-depth analysis of the skin, identifies the issue to be treated and establishes a precise diagnosis. On this basis, a personalized protocol is defined, adapted to the patient’s needs and skin characteristics.

What are the possible side effects of laser treatment ?

Aesthetic treatments based on the use of energy sources, such as lasers, cryolipolysis or radiofrequency, may be accompanied by side effects that should be anticipated before any management. Prior patient information is an integral part of the medical approach.
Laser treatments may cause temporary skin reactions, including redness, localized swelling or a sensation of heat or tingling. These manifestations most often resolve spontaneously within a few hours or a few days. However, depending on the technology used, the settings applied and the characteristics of the skin, more significant reactions may occur, such as superficial burns, crust formation or changes in pigmentation. Darker skin types require particular attention, as increased melanin content may enhance energy absorption and expose to a higher risk of burns or secondary hyperpigmentation.
Cryolipolysis may lead to local effects related to the action of cold, such as redness, bruising, a sensation of numbness or prolonged sensitivity of the treated area. In rare cases, transient pain or a temporary alteration of skin sensitivity may be observed.
Radiofrequency treatments are generally well tolerated. They most often cause a sensation of heat associated with mild and transient erythema. Nevertheless, inappropriate settings or improper use of the technology may lead to superficial burns.
The limitation of these effects relies on a thorough medical assessment, the appropriate choice of technique and parameters adapted to the patient, as well as strict compliance with recommendations before and after each session. Management carried out in a secure medical setting and by an experienced physician is essential to ensure the effectiveness and safety of treatments.

What is non-invasive aesthetic medicine ?

Non-invasive aesthetic-oriented medicine brings together treatments that improve the face, skin and body without surgery. These treatments are performed using devices such as lasers, radiofrequency and other medical devices.

The number of sessions required depends on the type of treatment, the severity of the aesthetic concern and the area to be treated. Some patients see results after a single session, while others may require several sessions to achieve the desired results.

Lasers use beams of light to target chromophores : water, blood or pigment. They can heat the target, cause it to rupture or vaporize it.

Laser skin treatments can significantly improve wrinkles, scars, pigmented spots and skin quality. The skin becomes smoother, more even and more youthful.

Most non-invasive aesthetic-oriented medicine treatments are well tolerated and are virtually painless. Some treatments may cause slight discomfort, but the application of an anesthetic cream improves patient comfort.

Side effects depend on the treatment performed and the device used. They are temporary : redness, swelling and skin sensitivity. It is important to follow the post-treatment advice given by the physician in order to minimize risks and speed up healing.

Non-invasive aesthetic medicine treatments are suitable for almost all patients, whatever their skin type or age. A prior consultation with an experienced doctor helps to determine the most appropriate options according to the patient's needs and expectations.

No, laser treatment does not accelerate skin aging. It has the opposite effect : it stimulates collagen production and improves skin elasticity and quality. This gives a younger and fresher appearance.

Only physicians are authorized to perform medical laser treatments.

Laser is a medical technology used to improve certain skin characteristics and treat various aesthetic conditions. A laser emits beams of light that make it possible to treat different aesthetic concerns such as pigmented spots, wrinkles, acne scars and vascular lesions. There are different types of lasers, each adapted to specific issues.

Yes, laser treatment can be very beneficial for the skin when it is used correctly by an experienced physician. Laser treatments can stimulate collagen production, reduce wrinkles, improve skin quality and treat conditions such as hyperpigmentation and scars. 

Yes, laser treatment is very effective for treating wrinkles. Lasers, particularly fractional ablative lasers and continuous ablative lasers, stimulate the production of collagen and elastin, essential proteins for skin firmness and elasticity. This allows a significant reduction of wrinkles and fine lines. The skin becomes smoother and more supple.

The type of laser used for the face depends on the patient’s needs and the issues to be treated. Fractional lasers, such as Fraxel, are used for mild skin rejuvenation, while ablative lasers, such as CO2 or Erbium, are employed for deep resurfacing. The NdYag laser is used to treat vascular lesions. Each laser has its own indication.

When it is used correctly by an experienced physician, laser treatment does not damage the skin. However, temporary side effects such as redness, swelling or mild sensitivity may occur. It is essential to follow post-treatment instructions to avoid complications and accelerate healing.

After a laser session, the skin may be red, swollen and sensitive, similar to after a sunburn. These effects are temporary and fade within a few days. For ablative lasers, the skin may peel and scabs may appear during the healing phase. 

Laser treatments are designed to treat aesthetic concerns, not to cause them. Temporary redness or slight pigmentation may appear after the treatment. These effects disappear quickly. Strict adherence to post-treatment instructions and recommendations is essential to avoid permanent side effects.

It is recommended to avoid sun exposure for at least two weeks after a laser session to allow the skin to heal properly and to avoid the risk of pigmentation. This timeframe varies depending on the treatment performed, the type of laser and the skin type. 

A laser session begins with a consultation during which the physician analyzes the skin and discusses the patient’s objectives. During the session, the area to be treated is disinfected, and the eyes are protected with safety goggles. The laser handpiece is placed on the skin and the treatment begins. The patient feels a tingling or warming sensation. The duration of the session varies depending on the treated area and the type of laser used.
