Patch Test Results with Standard and Cosmetic Series in Patients with Suspected Cosmetic-Induced Contact Dermatitis

摘要

Background and Design: Our aim was to evaluate the hypersensitivity to cosmetic chemicals in patients with clinically suspected cosmetic-induced contact dermatitis in Bursa and the South Marmara Region (Turkey) by patch testing with standard and cosmetic series.Material and Method: Seventy-three patients with clinically suspected contact dermatitis due to cosmetics were patch tested by the European standard series and cosmetic series. The patch test results were analyzed as percentages. x2 test was used to demonstrate the relationship between cosmetic products and cosmetic allergens.Results: 90.4% of patients in our study group were female and 9.6% were male; the median age was 37.5 (range 16-71) years. The most commonly involved parts of the body were the face (49.3%), hands (16.4%), periocular region (6.8%), lips (6.8%), and the neck (5.5%). The most common offending cosmetic products causing allergic contact dermatitis were soaps and cleansing lotions (32.8%), moisturizer creams (21.9%), make-up (15.0%), and hair dyes (9.6%). 41.0% of patients showed positive reaction to at least one cosmetic allergen included in either standard or cosmetic series. The cosmetic allergens in the standard series and the rates of positivity were as follows: fragrance mix (6.8%), lanolin alcohols (5.5%), paraphenylenedaimine (2.7%), colophony (1.4%), paraben mix (1.4%), formaldehyde (1.4%), and methylchloroisothiazolinone (Kathon CG) in descending order. The most common offending cosmetic allergen groups were preservatives (21.9%), antioxidants (8.2%) and fragrances (6.8%). Conclusion: Allergic or irritant contact dermatitis due to cosmetics should be considered in cases of eczema involving face, neck, eyelids, lips, scalp or hands. Patch testing with cosmetic series beside standard series would be more helpful in detecting the responsible allergen(s).
