To the Editor.—  We have had the opportunity to care for several patients with photosensitive contact dermatitis to men's after-shave products. Our identification of the fragrance ingredient that caused the photosensitivity prompts us to report preliminary findings in two of these cases.

Methods.—  Patch testing was done according to the recommendations of the North American Contact Dermatitis Group (NACDG).1 Scoring of results was done according to NACDG criteria. Photopatch testing was done according to the following method. Suspected photosensitizers were applied in duplicate as routine closed patch tests. After 24 hours one set of patches was removed and exposed to ultraviolet-A radiation (maximum output at 365 nm, ≈ 6 mW/sq cm) for ten minutes at a distance of 16 cm. The second set of patches was uncovered 48 hours after application, and the results were scored according to NACDG criteria two and seven days after application.
