Abstract

 This study aimed to examine the incidence of cosmetic dermatitis in 2014, and identify cosmetic allergens and responsible cosmetics. We performed a 48-hour closed test on the backs of patients who consulted our clinic on suspicion of cosmetic dermatitis in 2014. Patch testing was performed with each patient's own cosmetics, the Japanese standard series, cosmetic allergens, and hair product allergens that were possibly related with their dermatitis. Results were assessed according to the International Contact Dermatitis Research Group recommendations. A reaction stronger than or equal to (+) was regarded as a positive reaction. We patch tested a total of 63 patients with suspected cosmetic dermatitis. Of these, 22 patients demonstrated positive reactions to their cosmetics. The cosmetics most frequently responsible were hair dye products. We reported a total of 22 patients with allergic contact dermatitis from cosmetics in 2014. We did not find any new cosmetic allergens in this study.
