A Case Report On Sunscreen Induced Contact Dermatitis

Background: PCOS-related acne is commonly treated with topical retinoids, antibiotics, and sunscreen, but chemical UV filters like oxybenzone can cause hypersensitivity reactions. Case Presentation: A 20-year-old female with PCOS developed facial redness, itching, exfoliation, and fever (102°F) after applying a sunscreen containing oxybenzone overnight. Lab findings showed elevated eosinophils (13.1%), indicating an allergic reaction. Management: Treatment was discontinued, and she was prescribed Desonide, Allegra, Dolo 650, and Excela Moisturizer. The ADR was moderate, predictable, and probably preventable. Conclusion: This case highlights the need for patch testing, hypoallergenic sunscreen selection, and patient education to prevent sunscreen-induced hypersensitivity in acne-prone individuals.
