Ten out of 22 patients (45.5%) had a positive photopatch test. There were 20 positive photopatch test reactions found in these 10 patients, and all 20 positive reactions were of current relevance. The frequencies of the positive photopatch test reactions were 2\u2010hydroxy\u20104\u2010methoxybenzophenone (oxybenzone) (n<\/jats:italic>\u2009=\u20096), 2\u2010hydroxymethoxymethylbenzophenone (mexenone) (n<\/jats:italic>\u2009=\u20093), 2\u2010ethylhexyl\u20104\u2010dimethylaminobenzoate (n<\/jats:italic>\u2009=\u20091), ketoprofen gel (n<\/jats:italic>\u2009=\u20091) and the patient's own product (n<\/jats:italic>\u2009=\u20099).<\/jats:p><\/jats:sec>Conclusions<\/jats:title>Our study suggests that sunscreen is the most common photoallergen to date as opposed to musk ambrette, which was the most common photoallergen in our earlier study in 1991\u20131993.
