A Case of Photoallergic Contact Dermatitis due to Benzophenone-3 / 대한피부과학회지

ABSTRACT

Benzophenones are aromatic ketone derivatives of dibenzoylmethane, exhibiting absorption characteristics not only in the UVC and UVB spectral ranges but also in part of the UVA range, up to 360nm. They are commonly used for extending the spectrum of photoprotection. Benzophenone-3, one of the most popular benzophenones, is the most common cause of sunscreen allergy as well as a substitute of PABA. We report a case of photoallergic contact dermatitis due to benzophenone-3 of sunscreen.
