Initially, she experienced redness, swelling, and irritation consistent with allergic contact dermatitis, which resolved after discontinuing the product. However, within two weeks, persistent depigmentation developed in the affected areas. Examination confirmed vitiligo through Wood’s light fluorescence, while patch testing revealed positive reactions to paraphenylenediamine (PPD) and nickel, common allergens in cosmetics. This case suggests a possible link between allergic contact dermatitis and the onset of vitiligo, potentially mediated by systemic immune modulation and immune memory sensitization. We hypothesize that the allergic reaction initiated a localized immune response, which evolved into a broader immune dysregulation, unmasking a latent predisposition to vitiligo. The mechanism may involve activation of memory T cells anda “pro-inflammatory microenvironment”, leading to sustained melanocyte destruction. The eyelid area, with its thin skin and heightened permeability, may be particularly susceptible to immune-mediated damage. This phenomenon corresponds with the Koebner effect, wherein localized trauma induces vitiligo in predisposed individuals.1 This case underscores the importance of patch testing for allergen identif","cbCaiiFEO2Kg7YQw","https://ap.wps.com/l/cbCaiiFEO2Kg7YQw","pdf",1454154,"English","# Introduction\n# Case Report","[{\"question\":\"What condition was identified in the patient after eyeliner application?\",\"answer\":\"The patient developed vitiligo on the upper eyelids, confirmed by Wood’s light fluorescence under ultraviolet light.\"},{\"question\":\"Which allergens were found on patch testing?\",\"answer\":\"Patch testing showed positive reactions to paraphenylenediamine (PPD) and nickel, both common cosmetic allergens.\"},{\"question\":\"How quickly did depigmentation appear after stopping the eyeliner?\",\"answer\":\"Redness and irritation consistent with allergic contact dermatitis resolved after discontinuation, but persistent depigmentation developed within about two weeks in the previously affected areas.\"}]","Onset of vitiligo following contact dermatitis from eyeliner application in a 20-year-old female | PDF",1790730255]
