What are the contraindications for a chemical peel?

The contraindications for performing a chemical peel are just as important as its potential benefits. Not every patient is a suitable candidate for this procedure, and proper qualification as well as an assessment of the skin’s condition by a specialist are crucial to avoid adverse effects. Below is an in-depth overview of the most important contraindications:

1. Active Infections and Inflammatory Skin Conditions

Active Infections: The presence of bacterial, viral (e.g., herpes simplex), or fungal infections is a clear contraindication. The procedure may exacerbate the inflammatory state or lead to the spread of infection.
Inflammatory Conditions: Skin with active inflammatory conditions, such as pustular acne, dermatitis, or other acute reactions, should not be treated with a peel, as it may worsen the skin’s condition.

2. Highly Sensitive Skin and a Tendency to Scar Formation

Hypersensitivity and Allergies: Patients with a history of allergic reactions or a predisposition to hypersensitivity to the ingredients used in peels are more prone to irritation and complications.
Scar Formation: Individuals who tend to develop keloids or hypertrophic scars should avoid deep peels, as the procedure may trigger an uncontrolled healing response and exacerbate the scarring problem.

3. Dermatological Diseases

Chronic Skin Conditions: The treatment is not recommended for individuals suffering from psoriasis, eczema, rosacea, or lupus erythematosus. In these cases, a chemical peel may exacerbate the symptoms.
Autoimmune Skin Disorders: Autoimmune conditions require special caution, as intervening in the skin may trigger unpredictable reactions.

4. Use of Medications That Increase Skin Sensitivity

Retinoids: Individuals using retinoids (e.g., isotretinoin) must be cautious, as their skin becomes more susceptible to damage and irritation.
Photosensitizing Medications: Preparations that increase the skin’s sensitivity to sunlight or acids (e.g., some antibiotics and anti-inflammatory drugs) also represent a contraindication for undergoing a peel.

5. Pregnancy and Breastfeeding

Limited Data: Although not all types of peels are absolutely contraindicated during pregnancy, the limited data regarding their safety mean that deeper procedures are generally avoided. The same applies during breastfeeding.
Medical Consultation: Pregnant or breastfeeding women should consult their physician before the procedure to assess potential risks.

6. Recent Cosmetic or Surgical Procedures

Recent Treatments: After invasive facial treatments such as laser therapy, mesotherapy, or plastic surgery, the skin needs time to regenerate. Undergoing a peel during this period may lead to excessive irritation or disrupt the healing process.
Recovery Period: It is advisable to wait for a specified period, as recommended by the specialist, before undergoing a chemical peel.

7. Intense Hyperpigmentation and Other Specific Skin Issues

Inappropriate Indications: In cases of very intense hyperpigmentation, such as that resulting from previous improper treatments, there is a risk of worsening dyschromia. A thorough diagnosis and assessment of the skin condition are therefore necessary prior to the procedure.

A chemical peel is not a one-size-fits-all treatment. Contraindications include both general inflammatory and infectious conditions, as well as specific individual factors such as skin sensitivity, dermatological diseases, the use of certain medications, pregnancy, and recent cosmetic procedures. A proper consultation with a dermatologist or cosmetologist is essential to select the appropriate method and minimize the risk of complications, ensuring the achievement of the desired results while maintaining patient safety.
