Background In theory, all pigmented make‐up products may contain metal allergens including nickel. Eyelid dermatitis has previously been observed among nickel allergic dermatitis patients following exposure to nickel containing mascara and eye shadow. However, an association between nickel eyelid dermatitis and nickel in make‐up products remains controversial. Objective This cross‐sectional patch test study investigated whether the frequency of self‐reported cosmetic dermatitis from mascara or eye shadow use was higher among nickel allergic Danish women than women without nickel allergy. Methods In 2006, a total of 1843 18–69 year old women completed a postal questionnaire including questions on cosmetic dermatitis and were patch tested with nickel sulphate. Data were analysed by logistic regression analyses and associations were expressed as odds ratios (ORs) with 95% confidence intervals (CIs). Results The prevalence of nickel allergy was similar among women who reported cosmetic dermatitis from eye shadow or mascara and among women who did not report such symptoms. Cosmetic dermatitis was positively associated with self‐reported atopic dermatitis and age. Conclusion Overall, no association between having nickel allergy and reporting cosmetic dermatitis from mascara or eye shadow use was found in the general population. This does not exclude a causal relationship in selected cases.
