Medium TCA peel: treat wrinkles, pigment spots and acne scars
The medium TCA peel is an aesthetic medicine treatment that acts more deeply than the superficial peel in order to reduce wrinkles, pigment spots, acne scars and signs of photoaging.
The medium trichloroacetic acid (TCA) peel is recommended when skin imperfections are more pronounced and a superficial peel does not achieve the desired results.
At the Biolaser center in Saint-Louis, near Basel, Mulhouse, Lörrach and Weil am Rhein, each treatment is personalized after a medical consultation.
What is a medium TCA peel?
The medium TCA peel consists of applying a trichloroacetic acid (TCA) solution to stimulate the renewal of the deeper layers of the skin.
Unlike the superficial peel with fruit acids, it acts more intensely to treat more established imperfections, including:
- wrinkles and the first signs of aging;
- pigment spots;
- acne scars;
- signs of photoaging.
On the other hand, the aftermath is more marked and requires a few days of recovery. The choice of protocol is always made by the doctor according to your skin, your phototype and your goals.
When is a medium TCA peel recommended?
Thanks to its deeper action, the medium TCA peel is indicated when the imperfections are more pronounced or when a superficial peel does not achieve the desired result.
TCA peel for wrinkles and the first signs of aging
TCA peeling stimulates skin renewal and gradually improves its texture. It helps reduce fine lines, certain superficial wrinkles and the signs of photoaging, for smoother and more even skin.
Peeling for pigment spots
The medium peel may be recommended to treat certain pigment spots related to the sun or skin aging. By promoting the renewal of the deeper layers of the skin, it helps to even out the complexion and gradually fade dark spots.
Peeling for acne scars
The TCA peel is particularly interesting for improving the appearance of certain superficial to moderate acne scars. By stimulating skin regeneration, it gradually smooths the skin’s relief.
Peeling against photoaging
With age and repeated exposure to the sun, the skin gradually loses quality. The medium peel helps to improve skin texture, even out skin tone, and restore radiance to skin marked by time.
Peeling for certain actinic keratoses
In some cases, TCA peeling may also be offered to treat certain superficial actinic keratoses. A medical consultation is essential to confirm the indication and to ensure that a peel is the most suitable treatment.
What medium peels are offered at Biolaser?
The choice of the medium peel depends on many criteria: your skin type, your phototype, the nature of the imperfections and the desired results. During the consultation, Dr. Michaël Thanacody selects the most suitable protocol among several medical peels from Dermaceutic laboratories.

How does a TCA peeling session work?
Each medium TCA peel is preceded by a medical consultation in order to confirm the indication and define the most appropriate protocol.
Skin preparation is essential
As with superficial peels, a 14-day skin preparation is mandatory before each session. It is based on the daily application of cosmetic treatments prescribed by the doctor in order to optimize the effectiveness of the peeling and prepare the skin for the treatment.
The course of the session
The session usually lasts 15 to 30 minutes and includes several steps:
- Cleansing and preparation of the skin ;
- Application of the TCA peel, with a concentration adapted to your indication;
- Application of soothing treatments and reminder of the instructions to follow after the treatment;
- LED phototherapy (if indicated) to promote skin recovery.
During application, a sensation of heat or tingling is normal and gradually disappears after the session.
The number of sessions varies according to the indication treated. A personalized protocol is offered to you during the medical consultation.
What results can be expected after an average TCA peel?
The results of a medium TCA peel appear gradually as the skin is renewed. Thanks to its deeper action, it can correct more marked imperfections than a superficial peel.
Depending on your problem, the treatment can make it possible to:
- reduce wrinkles and the first signs of skin aging;
- fade certain pigment spots and even out the complexion;
- improve the appearance of certain acne scars ;
- smoothing the skin texture and improving its texture;
- restore radiance to skin marked by photoaging.
The results vary depending on the quality of your skin, the indication being treated and the protocol put in place. They are optimized when the peel is combined with the cosmetic preparation prescribed before the treatment, post-peel care and daily sun protection.

| Period | Usual skin evolution |

Precautions to be taken
To promote good recovery and optimize treatment results, it is recommended to:
- apply the restorative care prescribed by the doctor;
