Allergic contact dermatitis in masseurs from essential oils and fragrances may initially present on the hands, and thereafter may extend to involve the forearms, face, and neck. Essential oils are complex and may have as many as 100 distinct constituents in any one oil. In addition, variable concentrations within oils, degradation by-products, and quenching other effects make determining the sensitizing agent difficult. Masseurs are at risk of sensitization to essential oils, which may have cross-reactivity, pseudo-cross-reactivity, or concomitant sensitization to other fragrances and oils. Industry hygiene practices necessitate frequent hand washing, with further risks of sensitization to rinse-off product excipients like MI/MCI.
