In a retrospective study among 310 patients with ordinary contact dermatitis, 115 were found to have allergic contact dermatitis caused by cosmetic products. The most commonly involved sites were hands (including fingers) and face. The most frequently identified sensitizers were fragrances, including lichen and compositae extracts, preservatives and balsam of Peru. About 28% of the cutaneous reactions occurred among patients 20-29 years of age.
