What is treatment?
Fractional laser for scars represents a major advance in aesthetic medicine. It is a dermatology device that emits highly targeted light, split into thousands of microbeams. Each impact creates a multitude of micro-zones of thermal coagulation through the superficial and intermediate layers of the skin, while preserving healthy skin tissue between these areas. This principle, called “fractional photothermolysis”, stimulates cell regeneration and the synthesis of new collagen, resulting in a profound reorganization of the structure of the dermis.
Unlike traditional ablative laser, fractional skin resurfacing accelerates spontaneous healing and significantly reduces the risk of complications. Untouched skin serves as a cellular reservoir, accelerating repair and limiting social eviction. The Biolaser Center offers different laser platforms to adapt to each indication and phototype, thus guaranteeing personalized management of scars and texture irregularities.
The action of the fractional laser scars results in a microscopic ablation of the damaged tissue, followed by an intense renewal of the skin layers. This approach makes it possible to treat targeted areas without altering the entire skin, thus strengthening the repair process and promoting a natural result without a “mask” effect.
For what indications?
Fractional laser is indicated for all types of scars, whether they are atrophic acne scars, surgical scars, post-traumatic marks or post-chickenpox marks. Particularly effective on the face (cheeks, temples, chin, forehead), it can also improve the texture and appearance of the skin on the body (back, décolleté, arms, etc.).
Apart from the treatment of scars, this protocol is used for:
- Improvement of skin relief, dilated pores and superficial irregularities
- Correction of fine lines and early signs of aging
- Skin tightening and reviving dermal tone
- Treatment of stretch marks
- Correction of granular or impoverished skin texture
Thanks to its ability to revive collagen production and reshape the skin matrix, fractional laser scars offer a long-lasting solution where topical treatments or superficial peels would quickly show their limits. It is therefore aimed at all those who wish to reduce the visible marks of the past and regain even, soft and smooth skin.
How does a session work?
All care begins at the Biolaser Center with an in-depth medical consultation with Dr. Michaël Thanacody. This key step makes it possible to precisely identify the type of scar, its age, its depth, and to evaluate the skin phototype in order to exclude contraindications (recent bronze, pregnancy, active skin diseases, etc.).
The laser resurfacing session takes place in several stages:
- The area to be treated is thoroughly cleaned and made up.
- Application of a local anesthetic cream for 30 to 60 minutes for the patient’s comfort.
- Adjustment of the laser according to the parameters determined during consultation (depth, intensity, density of impacts).
- Fractional laser passes over the area: each microbeam targets the skin in a specific pattern. The patient feels tingling or a sensation of heat, which is well tolerated thanks to anesthesia.
- The duration of application varies (15 to 45 minutes) depending on the extent of the area to be treated.
- Immediate application of a post-treatment soothing cream and delivery of specific care instructions at home.
It is common to observe redness, a “sizzling” skin appearance, or even superficial mini-crumbles in the days following the session, testifying to a skin renovation in progress. The resumption of daily activities is possible quickly, except for sports activities or immediate sun exposure.
The fractional laser scars can be combined with other medical procedures, such as the Hollywood Peel (soft pigment laser), thus optimizing the quality of the skin texture and the uniformity of the complexion for complete rejuvenation.
How many sessions are necessary?
The protocol is adjusted according to the age and severity of the scars, the regenerative capacity of each patient and their objectives. In the majority of indications, 2 to 5 fractional laser sessions spaced 4 to 6 weeks apart will be proposed.
From the first session, a more even effect of “lifted” skin may appear after the initial redness has disappeared. However, collagen regeneration and reorganization continue to improve up to 3 to 6 months after the series of sessions, hence the progressive benefits. For very old, deep or thick scars (post-traumatic scars of the face or back, in particular), a longer protocol may be necessary, possibly combined with other techniques such as microneedling, deep peels or PRP.
The doctor carries out a regular reassessment to adjust or complete the management and guarantee the best results.
Fractional laser scars: expected results
The results of fractional laser on scars and skin texture are gradual. From the first session, we generally observe:
- Visible refinement of scars, which become smoother and better integrated into healthy skin
- A reduction in the contrast between the scar and the surrounding skin, erasing the “spot” or “relief” appearance
- A significant improvement in skin texture and radiance, making the complexion more even
- Noticeable reduction of enlarged pores and relief irregularities
- More toned, supple and plump skin
On the face, the benefits are particularly marked for acne scars, residual marks from surgery or injuries, and improvement of overall texture. On the body, for example with stretch marks, there is also skin softening and a visible reduction of streaks.
For very damaged or time-scarred skin, fractional laser can be combined with other medical procedures such as the Hollywood Peel (soft pigment laser), to even out the complexion and boost the quality of the skin.
The quality of the result depends on the regularity of the protocol, the respect of post-procedure instructions and the patient’s lifestyle. The benefits obtained are long-lasting, but it is imperative to avoid excessive exposure to the sun and to favor appropriate dermatological care to preserve the result over time.
Before/After: Clinical Studies and Patient Satisfaction
The clinical results of fractional laser scars are now the subject of numerous medical publications. Studies show a 50 to 80% improvement in the appearance of atrophic scars, as well as a measurable decrease in relief, induration (fibrous appearance) and irregular coloration. At the Biolaser Center, the opinions collected show a high level of satisfaction after three sessions, especially among patients with acne scars or persistent texture defects.
The satisfaction rate obviously depends on the respect of the personalized protocol, but also on the possible synergy with complementary treatments such as medical peels, microneedling or Hollywood Peel. The rate of scar reappearance remains extremely low when the maintenance instructions are followed.
“Before/after” medical photography allows objective monitoring of progress and reassures the patient about the expected result, without overestimation.
Possible side effects and safety of treatment
The latest generation fractional laser has an excellent safety profile when used in an expert medical center, on well-prepared skin and a suitable protocol. Common suites include:
- Localized erythema (redness), lasting for a few days depending on the depth of treatment
- Edema (swelling), especially around the eyes or on sensitive areas, regressing within 48 to 72 hours
- Fine peeling (peeling skin) for a few days, a sign of regeneration
- Formation of superficial crumbles that disappear spontaneously without leaving a trace
More rarely, certain complications may appear:
- Post-inflammatory hyperpigmentation, mainly in dark or dark skin, hence the importance of strict adaptation of parameters and photoprotection
- Bacterial or herpes superinfection (very rare), prevented by medical screening and post-procedure hygiene
- Wound healing disorders occurring mainly in the event of non-compliance with the instructions
The risk of permanent residual marks remains exceptional when post-operative care is respected and contraindications are ruled out during the initial consultation. The Biolaser Center’s follow-up reassures the patient at each stage and allows us to intervene early in the event of an adverse reaction.
Post-treatment advice
The post-procedure phase is essential to the success of fractional laser scar treatment. At the Biolaser Center, we provide each patient with a detailed protocol to optimize healing and limit any risk.
Typical guidelines include:
- Meticulous use of a total SPF 50+ sunscreen until the erythema has completely disappeared, and photoprotection maintained for up to one month after the last session
- Daily hydration of the treated area with suitable, non-comedogenic and hypoallergenic repair balms
- Strict avoidance of heat sources, such as saunas, steam rooms or swimming in pools for 8 to 10 days
- No scrubs, peels or irritants on the affected area before complete healing
- No occlusive make-up for the time of desquamation; Favor mineral formulas or doctors with the agreement of the center
- Be careful not to scratch or rub the crisps to avoid the risk of secondary pigmentation or infection
Dermatological follow-up is personalized. A follow-up visit may be offered between two sessions to adjust the care or reassure the patient about the progress of the skin repair. If you have any doubts about a symptom or possible infection (fever, localized pus, unusual pain), it is recommended to contact the center quickly to obtain medical advice and benefit from appropriate care.
Psychological support is sometimes useful in patients with visible scars for several years, in order to optimize adherence to the protocol and strengthen self-esteem in this phase of transformation.
Fractional Laser and Scar Prevention: Expert Tips
Fractional laser scars are also effective in prevention when applied following surgery or recent skin trauma. By intervening early, it prevents excessive fibrosis, homogenizes the transition between the scar area and healthy skin, and prevents the occurrence of hypertrophic or keloid scars.
The doctor evaluates the opportunity for early vs. late treatment on a case-by-case basis depending on the type of lesion, the age of the patient and the associated comorbidities. This strategy optimizes repair and limits visible long-term sequelae.

FAQ — The 5 common questions about fractional laser scars
Is fractional laser suitable for all skin types?
The majority of recent fractional lasers are compatible with all phototypes, but adapting the protocol is essential for dark or Asian skin to avoid any risk of post-inflammatory pigmentation. Only the prior consultation at the Biolaser Center makes it possible to establish a personalized roadmap for each patient and to adjust the parameters to guarantee safety and effectiveness.
Is there social eviction after treatment?
Marked redness for 48 to 72 hours followed by fine flaking is usual. The resumption of light professional activities is possible the next day, subject to strict application of the post-procedure instructions. Social eviction is therefore very limited, especially in the face of first-generation ablative lasers.
Can I treat several types of scars at once?
Yes, it is common to combine fractional laser on different types of scars during the same session (acne, trauma, post-surgery), adjusting the depth and density according to each area. Your doctor is in the best position to advise you on a comprehensive resurfacing plan and refer you to other related techniques if necessary, such as microneedling or skin resurfacing.
When are the final results visible?
The first changes appear in the first week (smoother skin, brightened complexion). The deep restructuring of collagen continues in the months following the last session, with the “peak” of improvement being reached between 3 and 6 months. It is therefore essential to plan your sessions taking into account the biological time frame for skin renewal.
Is fractional laser treatment painful?
Thanks to the prior application of an anesthetic cream, the treatment is well tolerated. The patient experiences warm and tingling sensations, which are rarely painful. A slight sensitivity sometimes persists for a few hours after the session, calmed by a soothing cream or a cold pack if necessary.
