Fragrances are the #1 cause of allergic contact dermatitis in Europe and North America, affecting people of all ages. Reactions range from mild contact urticaria (itching/hives) to systemic contact dermatitis, and the problem is growing as fragrances become more common in everyday products. Better allergen identification, labeling requirements, and consumer education are key to preventing sensitization.

This was a literature review that examined existing research on fragrance allergies, including epidemiology, evaluation methods, screening techniques, and current management approaches. The authors analyzed emerging fragrance allergens and reviewed recent legislation to identify gaps in allergen detection.
