Allergic contact dermatitis to fragrances: part 2.

Allergic contact dermatitis due to fragrances usually manifests as subacute or chronic dermatitis because fragrances are found in a wide range of products to which patients are repeatedly exposed. The typical patient is a middle-aged woman with dermatitis on her hands and face, although other sites may be affected depending on the allergen and the product in which it is found. The standard patch test series of the Spanish Contact Dermatitis and Skin Allergy Research Group (GEIDAC) contains 4 fragrance markers: balsam of Peru, fragrance mix i, fragrance mix ii, and lyral. Testing with a specific fragrance series is recommended in patients with a positive result to any of these 4 markers. The use of a specific fragrance series and new legislation obliging manufacturers to specify the fragrances used in their products, will help to improve the management of allergic contact dermatitis due to fragrances.
