Allergic contact dermatitis may occur due to a reaction to compounds found in temporary tattoos. These tattoos often contain a mixture of brown henna with a chemical called paraphenylenediamine (PPD), or black henna. Skin reactions to temporary tattoos are often due to allergies to PPD. Eczema results which then evolves into a postinflammatory change in pigmentation. The photo depicts postinflammatory hyperpigmentation that erupted after the application of a temporary tattoo. The discoloration may persist for a substantial amount of time.
