Photoallergic contact dermatitis to men's perfumes.

Three patients with photosensitive eruptions related to the use of different men's perfumes were evaluated. We found that they were photoallergic to musk ambrette, an inexpensive, readily available synthetic perfume ingredient. Studies of cross-reactivity with other perfumed colognes and after-shave lotions suggest that musk ambrette is present in clinically significant concentration in large numbers of other cosmetic products.
