Allergic contact dermatitis caused by a new temporary blue-black tattoo dye - sensitization to genipin from jagua (Genipa americana L.) fruit extract.

We report an extensively evaluated case of allergic contact dermatitis caused by a temporary Earth Jagua® tattoo. The allergen identified is genipin, a substance that is increasingly used for tattoos and as a therapeutic agent in medicine. This could result in an increase in the number of allergic reactions in the future.
