Photoallergic contact dermatitis is uncommon

Abstract: These results show a low yield of positive photopatch tests. Thus, despite the large increase in the use of UV filters over the last decade, the development of PA reactions remains rare. Furthermore, most of the common UV filter photoallergens identified in this study, including PABA, amyl dimethyl PABA and benzophenone-10, are now rarely used in sunscreen manufacture, while isopropyl dibenzoylmethane was voluntarily removed from the market in 1993. Currently, benzophenone-3 is the commonest contact photoaller… Show more

“…Entre eles estão o seu alto custo, ocasionado pelo alto valor de suas matérias-primas. Outras razões se relacionam à existência de estudos controversos que indicam possível potencial alergênico ou até mesmo tóxico, ocasionado pelo uso de filtros solares e possíveis produtos de degradação, principalmente no caso de filtros orgânicos (11)(12)(13). Este fato tem gerado tendência a buscar novos produtos com maior eficácia antissolar, estabilidade química, menor potencial alergênico e menor custo.…”

“…Among them is their high cost, caused by the high value of their raw materials. Other reasons are related to the existence of controversial studies that show a possible allergenic potential or even toxicity caused by the use of sunscreens and possible degradation products, particularly in the case of organic filters (11)(12)(13). This has generated a trend to seek new products with higher sunscreen effectiveness, chemical stability, lower allergenic potential and lower cost.…”

“…All patients with exposed surface eczema should be patch and photopatch tested. Photoallergic contact dermatitis is uncommon (Darvay et al, 2001). Review of the relevant allergens for photopatch testing shows that virtually all positive photopatch tests in recent years are because of sunscreen ingredients.…”

“…Photosensitivity from topical agents, once frequent and often associated with persistent reactions to light, is now becoming rare [3,4], as the main topical photosensitizers are removed from the market, or maybe photosensitivity is underreported or underdiagnosed [5]. On the other hand, and even though sun avoidance is recommended in those exposed to known photosensitizers, new drugs are reported to have photosensitizing properties, eventually associated with late problems.…”
