Abstract:
Ultraviolet (UV) filters may cause allergic and more frequently photoallergic contact dermatitis. Therefore, a photopach test should always be performed in case of a suspected contact sensitivity to UV filters. We report a case of a 65-year-old woman with a recurrent erythema of the face and décolleté after sun exposure despite application of a sunscreen. The (photo)patch test revealed a contact sensitivity to the UV filter butyl-methoxybenzoylmethane. Treatment with a topical glucocorticoid and avoidance of the particular UV filter led to a rapid improvement.
