  • Angular Cheilitis: Characterized by inflammation at the corners of the mouth, often due to fungal or bacterial infections.

  • Contact Cheilitis: Can be irritant or allergic, caused by external substances.

Classification of Allergic Contact Cheilitis

Allergic contact cheilitis is classified based on the allergen involved. It includes:

  • Cosmetic Allergens: Ingredients in lipsticks, balms, and glosses.

  • Dental Allergens: Materials used in dental procedures.

  • Environmental Allergens: Pollen, dust, and other airborne particles.

Symptoms and Signs

Common Symptoms

Common symptoms of ACC include:

  • Redness and swelling of the lips.

  • Itching and burning sensation.

  • Dryness and peeling of the skin on the lips.

Uncommon Symptoms

While less common, some individuals may experience:

  • Blisters and sores on the lips.

  • Cracked and bleeding lips.

  • Mild itching or tingling after applying lip products.

  • Slight swelling or redness.

  • Initial dryness and minor cracks.

Causes and Risk Factors

Biological Factors

Genetics play a role in the susceptibility to allergies. Individuals with a family history of allergies are at higher risk of developing ACC.

Environmental Factors

Environmental factors contributing to ACC include exposure to allergens in cosmetics and lip products. Pollutants and airborne particles can also exacerbate symptoms.

Lifestyle Factors

Lifestyle choices, such as the frequent use of various cosmetic products, smoking, and diet, can influence the likelihood of developing ACC. Smoking, in particular, can irritate the lips and increase sensitivity to allergens.

Diagnosis and Tests

Overview of Diagnostic Procedures

Diagnosing ACC involves a thorough medical history and examination of the affected area. Healthcare providers often start with identifying potential allergens based on the patient’s cosmetic use.

Importance of Patch Testing

Patch testing is a crucial diagnostic tool for ACC. It helps identify specific allergens causing the reaction, enabling targeted treatment and prevention strategies.

How Patch Testing is Conducted

Patch testing involves applying small amounts of potential allergens to the skin, usually on the back, and observing for reactions over 48–72 hours. This test is painless and provides valuable insights into which substances to avoid.

Treatment Options

Medical Treatments

Medical treatments for ACC may include:

  • Topical Steroids: To reduce inflammation and itching.

  • Antihistamines: For managing allergic reactions.

  • Emollients: To hydrate and protect the lips.

Therapies

Therapies such as phototherapy may be recommended for severe cases. This involves using ultraviolet light to reduce inflammation and improve skin health.

Lifestyle Adjustments

Making lifestyle adjustments is crucial for managing ACC. This includes avoiding known allergens, using hypoallergenic lip products, and maintaining good lip hygiene.

Preventive Measures

Avoiding Allergens

Identifying and avoiding allergens is the primary preventive measure. Patients should read product labels carefully and avoid those containing known irritants.

Safe Lip Products

Using hypoallergenic and fragrance-free lip products can significantly reduce the risk of ACC. Products labeled as “dermatologist tested” are often safer choices.

Daily Care Tips

Daily care tips for preventing ACC include:

  • Keeping lips moisturized with safe products.

  • Avoiding licking the lips, as saliva can worsen dryness.

  • Staying hydrated to maintain healthy skin.
