Clinical case of allergic blepharoconjunctivitis in a girl after eyelash dyeing

Allergic blepharoconjunctivitis is a common condition that occurs as a result of allergic reactions to various allergens, including components of cosmetics. One of the most common and dangerous allergens is para-phenylenediamine, which is used in hair dyes, mascaras, and other cosmetic products. This is especially important for children, whose bodies are more sensitive to various irritants. Although the allergy to para-phenylenediamine has long been recognized in medical practice, cases of allergic reactions in children, particularly after using cosmetics for dyeing eyelashes, remain rare and poorly understood. This clinical case describes the development of allergic blepharoconjunctivitis in an 11-year-old girl after dyeing eyelashes. It highlights the importance of a cautious approach to the use of cosmetics in children and the need for increased awareness of possible allergic reactions to cosmetic ingredients. Attention is focused on the need for timely diagnosis and appropriate treatment to avoid complications, as well as allergy testing to accurately identify the allergen and prevent future reactions. This clinical case is crucial for raising awareness of the potential risks of allergic reactions to cosmetics in children.
