When sunscreens do not help: allergic contact dermatitis to UV filters

摘要

Ultraviolet (UV) filters may cause allergic and more frequently photoallergic contact dermatitis. Therefore, aphotopach test should always be performed in case of asuspected contact sensitivity to UV filters. We report acase of a65-year-old woman with arecurrent erythema of the face and decollete after sun exposure despite application of asunscreen. The (photo)patch test revealed acontact sensitivity to the UV filter butyl-methoxybenzoylmethane. Treatment with atopical glucocorticoid and avoidance of the particular UV filter led to arapid improvement.
