Medical peeling: types, benefits and contraindications

Le teint terne, les taches pigmentaires, les cicatrices d’acné ou le vieillissement cutané sont des problématiques qui concernent aussi bien les femmes que les hommes, à tout âge. Pourtant, il existe aujourd’hui des solutions médicales efficaces pour retrouver une peau plus nette, plus uniforme et visiblement plus lumineuse. Parmi ces traitements, le peeling médical occupe une place centrale en dermatologie esthétique moderne.

At the Biolaser Center, located in Saint-Louis near Basel, Lörrach and Freiburg, Dr. Michaël Thanacody offers personalized support where safety and medical expertise are paramount, in order to precisely meet the expectations of each patient. Find in this article everything you need to know about medical peeling: types, indications, results, precautions, procedure, and find out the answers to all your frequently asked questions.

What is a medical peel?

A medical peel is a controlled dermatological procedure that consists of applying a chemical solution to the skin in order to cause a more or less deep exfoliation depending on the type of peel chosen. This action helps to regenerate the skin, erase imperfections, reduce certain pigment spots and superficial wrinkles, tighten pores or smooth the skin texture. The cell renewal induced in this way is accompanied by a stimulation of collagen, a true pillar of the skin’s youthfulness.

There are mainly three types of medical peels, adapted according to the skin phototype (skin color), the nature and depth of the abnormalities:

• Le peeling superficiel : ce peeling agit sur les couches superficielles de l’épiderme. Les principaux actifs utilisés sont l’acide glycolique et l’acide salicylique. Il affine le grain de peau, illumine le teint et convient à tous les types de peau, même les plus sensibles ou les peaux mates, lorsqu’il est parfaitement dosé et réalisé en cabinet.
• Le peeling moyen : principalement à base d’acide trichloroacétique (TCA), il agit jusqu’à la jonction derme-épidermique. Il cible efficacement les taches, les ridules et les cicatrices d’acné modérées, tout en améliorant la texture globale de la peau.
• Deep peeling : reserved for specific indications such as deep wrinkles or certain marked signs of aging, it requires rigorous hospital supervision because of its power and the heavier consequences it generates. This peel is not offered in all practices and remains rare.

The modern medical peeling protocols at the Biolaser Center are also based on combinations of active ingredients to offer a totally personalized and safe treatment, both in intensity and frequency of sessions.

For which indications should I benefit from a medical peel?

The medical peel is not only aimed at a limited category of patients, but is suitable for both young and mature skin, men and women. It aims to treat many indications that are encountered on a daily basis in dermatology and aesthetic medicine:

1. Skin rejuvenation and radiance of the complexion

Dull complexion, facial fatigue, uneven skin texture and loss of radiance are all reasons for consultation. Thanks to the stimulation of cell renewal, the superficial peel improves skin luminosity, erases certain irregularities and gives the skin a fresher appearance from the first sessions. This treatment is particularly appreciated in the off-seasons, especially at the end of winter to recover vitality.

2. Correction of pigment spots and melasma

Les taches solaires, rougeurs, lentigos et le mélasma appelé aussi masque de grossesse, sont des désordres pigmentaires fréquents. Les peelings chimiques adaptés (acide glycolique, TCA à différentes concentrations) permettent une exfoliation ciblée des couches pigmentées et une amélioration progressive du teint, particulièrement sur les phototypes I à III. Pour des cas complexes ou récalcitrants, ils sont intégrés à une prise en charge globale de la pigmentologie.

3. Acne-prone skin, blemishes and enlarged pores

L’acné active, les points noirs, les pores dilatés comme les cicatrices résiduelles de poussées d’acné répondent très bien au peeling médical, en particulier à base d’acide salicylique ou d’acide glycolique. Les peelings aident à désincruster les pores, prévenir l’apparition de lésions, lisser la texture de la peau et contrôler la production de sébum. En complément, le Hollywood Peel au Centre Biolaser propose un nettoyage en profondeur au laser, adapté pour les peaux réactives et sujettes aux imperfections.

4. Reduction of fine lines and wrinkles

The medium peel, especially with TCA, is a major asset for skin with superficial wrinkles and fine lines, around the mouth, forehead or eyes. This treatment, once carried out in a doctor’s office, stimulates collagen synthesis and allows a noticeable reduction of small skin folds, for rejuvenated skin.

5. Correction of acne scars and residual marks

Les cicatrices atrophiques laissées par l’acné retrouvent une surface plus homogène grâce au peeling moyen ou à la combinaison avec d’autres actes médico-esthétiques, tels que le microneedling ou le laser fractionné. Les résultats sont encore optimisés en associant différentes technologies lors d’un plan de traitements individualisé.

6. Support for other aesthetic treatments

Le peeling médical peut également être utilisé comme préparation ou complément à d’autres procédures de médecine esthétique (injections, laser, LED, Hydrafacial,etc.) pour maximiser l’efficacité globale et pérenniser les résultats.

How does a medical peeling session work?

Before any first medical peeling session, a mandatory medical consultation is carried out. The doctor analyzes the general condition of the skin, looks for possible contraindications (infections, herpes, pregnancy, photosensitizing treatments, tanned or very reactive skin), specifies the achievable objectives and defines the type of medical peel suitable.

The course of a session includes:

1. Preparation of the skin : rigorous make-up removal and cleansing, possible application of a preparation lotion to degrease and promote the uniform penetration of the agent.
2. Application of the peel: the chemical agent (glycolic acid, TCA, salicylic acid, etc.) is applied with a medical or cotton brush, to the face, neck, décolleté or hands. The application time is controlled according to the skin’s reaction and the desired effect.
3. Sensations during the session : tingling, heat, moderate burning sensation, generally well tolerated thanks to continuous medical supervision during the application. Any sign of intolerance leads to the cessation of the procedure.
4. Neutralization and soothing : Rinse the treated area thoroughly, immediately apply a soothing and repairing cream.
5. Post-procedure information and advice : each patient leaves with detailed post-peel instructions to limit risks and optimize recovery.

An at-home skin preparation (gentle exfoliating cream or special serum) can be prescribed 1 to 2 weeks before the first session, especially for medium peels or if the skin is particularly sensitive.

After the treatment, a transient redness, similar to a slight sunburn, may occur. A feeling of tightness or moderate flaking is common, a sign of ongoing cell renewal.

How many medical peeling sessions are necessary?

The number of sessions depends on several factors: the depth of the peel, the problem to be treated, the individual sensitivity and the desired result. The protocol is ALWAYS individualized at the Biolaser Center.

• Superficial peeling: often performed as a treatment of 3 to 6 sessions, at a rate of one act every 15 to 21 days. These peels allow a global, progressive and gentle improvement of complexion, skin texture and slight irregularities.
• Medium peeling (TCA): most often performed in 1 to 3 sessions spaced 4 to 6 weeks apart. These sessions are more marked in terms of result and recovery.
• Deep peeling: a single session is enough in the majority of cases for a marked overall rejuvenation, with a significant recovery time (social eviction, long crusting).

The medical peel offers cumulative effects: the more complete the cure and the better the maintenance protocol is respected (sun protection, hydration, home relay), the longer lasting the result will be.

Expected results and effectiveness of medical peeling

The first benefits of a medical peel are usually observed very quickly, from the first week:

• Clearer skin, smoother texture, tightened pores
• Reduction of pigment spots and small imperfections
• Visible improvement in radiance and evenness of the complexion
• Reduction of fine lines (especially with medium or deep peels)
• Gradual disappearance of acne marks and dilated pores

For glycolic acid peels, the “healthy glow” effect is immediate, the skin appears clarified, soft and luminous. After a TCA (medium) peel, the in-depth regeneration results in a significant reduction in pigmented lesions, scar marks or signs of ageing.

In complex cases (deep scars, marked photoaging), several sessions combined with other techniques (laser, microneedling, LED, etc.) may be necessary to achieve an optimal and natural result.

The sustainability of the result depends on:

• Strict compliance with pre- and post-peeling instructions;
• The choice of peel adapted to your phototype (color and natural reaction of the skin);
• Regular follow-up in aesthetic medicine to anticipate possible complications or adapt complementary care.

With an adapted maintenance plan (annual session, adapted routine, sun avoidance), the benefits of a medical peel can be seen in the long term.

Side effects and precautions after a medical peel

The safety of medical peels is based on the qualification of the doctor and the strict adherence to individual recommendations. In experienced hands, side reactions are limited, but it is advisable to stay informed about the potential effects:

• Redness, a feeling of heat, tingling : normal at the end of the session, they give way in a few hours to days depending on the intensity of the treatment.
• Peeling, alopecia areata : cell renewal leads to skin that “peels” for a few days. Dead skin should not be torn off.
• Skin sensitivity : temporary fragility, reactivity to touch and to cold or wind. The use of moisturizing and repairing treatments is recommended.
• Post-inflammatory hyperpigmentation : risk in dark or dark skin, or in case of sun exposure without adequate protection. This risk is reduced by proper preparation and the prescription of a high-safety sunscreen.
• Hypopigmentation, scars, infections : extremely rare, occur especially in the event of non-compliance with instructions or a procedure carried out without medical supervision.
• Herpes reactivation : report any history of cold sores for preventive treatment.

In the event of an unusual reaction, it is imperative to contact the centre or your doctor as soon as possible.

Tips to follow after a medical peel at the Biolaser Center

After each medical peeling session, it is essential to optimize skin recovery with simple but essential gestures:

• Moisturizing, repairing: Apply generously the cream recommended by your doctor, several times a day, until redness or signs of flaking disappear completely.
• Strict sun protection: the daily application of a very high protection sunscreen (SPF50+) is mandatory for at least 1 to 2 months after each peel, even in winter and indoors. Avoid direct sun exposure, including UV lamps or sunbeds.
• Avoidance of irritating products: temporarily ban cosmetics based on alcohol, fruit acids (AHAs), exfoliating or retinoid active ingredients, as well as mechanical scrubs, until complete recovery. Follow the recommendations made at the centre to the letter.
• Do not scratch or tear off dead skin: this greatly limits the risk of scars, abnormal pigmentation or infections.
• Medical follow-up: do not miss your check-up appointments or scheduled sessions to guarantee the safety and effectiveness of the protocol started.

Adopting a personalized skincare routine at home, rich in moisturizers and soothing active ingredients, allows you to offer your skin an ideal environment for regeneration, limit inconveniences and perpetuate the results of your medical peel.

FAQ – Frequently Asked Questions About Medical Peeling

Is the medical peel painful?

The feeling depends on the type of peel applied: superficial peels cause a slight tingling or a temporary feeling of heat, quickly calmed by soothing treatments. Medium peels (TCAs) induce a more marked but brief burn, monitored by the doctor throughout the session (which never exceeds 10-15 minutes). No general anesthesia is required; In some cases, a local anesthetic cream may be offered if the patient wishes.

Is the medical peel suitable for all skin types?

Yes, as long as the formula, dosage and protocol are adapted to the phototype and skin sensitivity. Dark and dark skin requires specific preparation and increased vigilance to avoid the risk of hyperpigmentation. Medical expertise is decisive in preventing all risks and ensuring safety.

When can I reapply makeup after a medical peel?

After a superficial peel, it is usually possible to reapply make-up to the treated area within 24 to 48 hours, provided that there is no longer excessive redness or visible erosion. For medium peels, it is better to wait until the end of the desquamation phase, i.e. 7 to 10 days, and favor non-comedogenic makeup products, such as mineral makeup.

Is it possible to combine medical peeling with other treatments?

Oui, la combinaison de plusieurs techniques (peeling, Hollywood Peel au laser, microneedling, LED, injections, mésothérapie) permet d’attaquer différentes problématiques simultanément et de booster les résultats. Le médecin détermine l’ordre et le calendrier des séances pour optimiser l’efficacité et la tolérance.
