Hyperpigmentation treatment: melasma and pigment spots

With the return of sunny days, many patients notice the appearance or accentuation of pigment spots on the face, neck or hands. Whether it is melasma, solar lentigines or post-inflammatory hyperpigmentation, these alterations can alter skin radiance and generate aesthetic discomfort. In recent years, hyperpigmentation treatment has benefited from many technological advances, offering effective and safe solutions to regain a harmonious and luminous complexion.

At the Biolaser Center, in Saint-Louis, near Basel (Switzerland), Lörrach and Freiburg (Germany), our experienced medical team, led by Dr. Michaël Thanacody, offers dedicated protocols, combining medical lasers, depigmenting peels and personalized advice. This article details everything you need to know about hyperpigmentation treatment, its indications, how it works and the precautions to adopt to ensure that the results last.

What is hyperpigmentation treatment?

Hyperpigmentation treatment includes all medical procedures aimed at correcting skin pigmentation disorders, whether they are dark spots, melasma (“pregnancy mask”) or sun marks. These procedures, carried out at the Biolaser Centre by specialists, are based on scientifically validated techniques to attenuate, or even eliminate, the excess melanin responsible for dark spots.

The reference in this field is the pigment laser, which is able to precisely target accumulated melanin without altering healthy skin. Solar lentigines (age spots or “brown spots of the sun”) respond particularly well to this approach. In addition, depigmenting peels, prescription topical treatments, and some combination therapies offer a solution tailored to each skin profile and the precise nature of hyperpigmentation.

A dermatological diagnosis is essential before any treatment initiation, to individualize the protocol and prevent any side effects, especially in patients with a history of acne, rosacea or hormonal disorders.

For what indications?

Hyperpigmentation treatment at the Biolaser Center in Saint-Louis concerns many common indications, especially after winter periods when the skin, less exposed to the sun, is ideal for aesthetic care:

1. Melasma

Melasma manifests as dark, diffuse, symmetrical patches on the cheeks, forehead, or upper lip. This pigmentary pathology mainly affects women and is caused by sun exposure, hormonal variations and certain genetic factors. Its management requires patience, gentleness and consistency, under penalty of recurrence.

2. Solar lentigines and post-sun spots

Solar lentigines or age spots are the direct consequence of chronic exposure to UV rays. They appear on frequently exposed parts of the body — face, hands, décolleté — and reflect the “sun capital” of the skin. Treatment is based on pigment laser sessions or, in some cases, intense pulsed light, with rapid and long-lasting results.

3. Post-inflammatory hyperpigmentation

Following skin inflammations (acne, eczema, procedures, injuries), brown spots sometimes persist for several weeks or months. This type of hyperpigmentation requires a gradual and non-aggressive approach, especially on dark or dark skin, so as not to aggravate the pigmentation imbalance.

4. Pigmented erythrosis and poikiloderma

Some skin conditions, characterized by a combination of redness, atrophy and irregular pigment spots, such as civatte poikiloderma, require a treatment combining vascular and pigmentary lasers for an overall aesthetic improvement.

An accurate diagnosis is essential to differentiate between these types of spots and adapt the therapeutic strategy. This is based on a thorough medical examination and, if necessary, a dermatoscopic examination carried out during the initial consultation at the Biolaser Centre.

How does a session work?

The hyperpigmentation treatment protocol at the Biolaser Center is based on a rigorous methodology, in accordance with the best practices of aesthetic dermatology.

Preliminary medical consultation

Each treatment begins with a detailed evaluation of the skin, analysis of the medical history and search for contraindications. A personalized care plan is then proposed, then validated by informed consent, guaranteeing the patient’s complete information on the techniques, the expected follow-up and the expected results.

Skin preparation

Depending on the approach chosen (laser, peeling, etc.), the skin may require a few days of preparation: depigmenting cream, skin stabilization or photosensitizing products. These precautions optimize the effectiveness of the treatment and limit adverse reactions.

Pigment laser session

The practitioner targets the spots using a specific laser (Q-Switched, picosecond). Short pulses of light break up the accumulated melanin, causing a local reaction (tingling, moderate heat) that is very well tolerated thanks to a skin cooling system. The procedure takes about 15 to 30 minutes depending on the areas to be treated.

After the session, the skin may show a grayish coloration, a slight edema or a transient whitening. These effects are normal: a return to a normal social life is possible the next day, subject to scrupulous compliance with post-treatment recommendations.

Peels and Combined Protocols

Melasma treatment is sometimes based on superficial acid-based peels (glycolic, trichloroacetic, kojic) or custom-made depigmenting creams. The success of combined treatments (laser combined with peels) is validated in certain complex cases in order to increase the effectiveness without multiplying the risks.

How many sessions are necessary?

The number of hyperpigmentation treatment sessions depends on the initial diagnosis, the severity of the lesions, their density and your phototype:

• Solar lentigines : 1 to 2 laser sessions are often enough to reduce or make the spots disappear. For large or deep areas, 1 to 2 additional interventions are sometimes necessary.
• Melasma: a step-by-step course is recommended. It generally starts with 3 to 5 sessions, spaced 2 to 4 weeks apart, associated with strict topical management and assiduous photoprotection.
• Post-inflammatory hyperpigmentation : the treatment most often requires 2 to 4 sessions, with regular reassessment according to the sensitivity and cell renewal of the skin.

Each treatment plan is modified and adjusted over the course of the consultations according to the skin’s reaction and the patient’s expectations, always with the objective of natural and harmonious results.

Expected results and benefits

The treatment of hyperpigmentation offers, when properly conducted, significant benefits:

• A visibly more even, even and radiant complexion
• The reduction, lightening or even disappearance of the targeted spots
• Rejuvenated, luminous skin free of its “tarnished” appearance
• An improvement in psychological comfort and self-esteem linked to the quality of the complexion

Solar lentigines very quickly give way to clear skin (from the^2nd week), while melasma requires extreme vigilance to prevent reappearance. Close medical follow-up and continued photoprotection are essential to the long-term results.

It is important to note that some hyperpigmentation, especially on dark skin or in cases of severe melasma, can recur after a new sunburn or the early cessation of treatments. The Biolaser Center team provides personalized follow-up to prevent and correct any pigmentary rebound.

Possible side effects

New technologies (modern lasers, gentle peels) have an excellent tolerance profile, provided they are used by trained professionals:

• Localized redness or edema remaining 24 to 48 hours after the session
• Slight tingling or heating sensation in the treated area
• Possible formation of thin crusts or peeling (dandruff) on the targeted spots
• In rare cases: paradoxical hypo- or hyperpigmentation, especially on dark skin, requiring an adaptation of the protocol

Inappropriate use of a laser, peel or topical agent leads to the risk of irregular depigmentation or a “rebound” effect (spots that become more pronounced). Hence the need to entrust the hyperpigmentation treatment to a recognized and experienced team, such as that of the Biolaser Center in Saint-Louis.

Post-treatment advice: preserving and optimising your results

Scrupulous compliance with post-treatment instructions is a prerequisite for the success and safety of hyperpigmentation treatment. Here are the habits to adopt immediately after your session:

• Strictly avoid any exposure to the sun or UV rays for at least 4 to 6 weeks (hat, glasses, SPF 50+ renewed every 2 hours in case of going out)
• Do not rub, scratch or remove scabs or dandruff, as this may increase secondary hyperpigmentation
• Apply a non-comedogenic healing or repairing cream morning and evening
• Continue to apply depigmenting or soothing treatments as prescribed by the doctor
• In the presence of persistent redness, encourage the application of thermal water as a mist and avoid occlusive make-up for the first few days
• Scrupulously respect the check-up appointments to allow a personalized follow-up and anticipate any possible complication

Close support in the immediate aftermath and at a distance (15 days then 1 month) optimizes recovery and prolongs the benefits of the protocol initiated. This also makes it possible to adjust, if necessary, certain complementary treatments to prevent the reappearance of pigment spots.
