The frequency, and thus availability to patients, of ultraviolet (UV) filters contained within sunscreens changes over time. Obtaining current data on filter availability is necessary when considering which agents to include in sunscreen series for patch and photopatch testing of patients. A survey of sunscreen products was undertaken in Dundee, UK, in 2010. In total, 337 products were identified, with a median sun-protection factor of 30 (range 2–50+). In these products, 19 UV filters were identified, of which the most common was butyl methoxydibenzoylmethane. Compared with data from 2005, most filters had an increase in frequency of inclusion, with a trend towards broader spectrum protection. This information should be of use to clinicians considering investigation of contact and photocontact allergy. It also aids determination of the allergenic potential of these filters when reports of allergy and photocontact allergy arise in the literature.
