Contact Allergy to Limonene from a Home-Made Cosmetic
Abstract
Contact allergy to fragrances is very common. It is the second sensitizer in contact allergic dermatitis, after nickel sulphate. The fragrance mix and Balsam of Peru affects about 50–80% of patients affected by fragrance allergy, but the study of recent literature highlights new markers implicated in the pathogenesis of this dermatitis. We report an unusual case of contact allergy to limonene in a young woman after daily use of a self-made cosmetic product containing lemon juice and peel (rich in limonene), with a positive reaction to Balsam of Peru to patch test and a positive reaction to patch by patch performed with her cosmetic and lemon peel. This simultaneous sensitization has been previously described in literature.
