Personal care products are the source of most allergic and irritant contact dermatitis in male patients with facial dermatitis, according to a study published in JAMA Dermatology.

In a separate study that also used the North American Contact Dermatitis Group database, patients suspected of having allergic contact dermatitis with anogenital involvement should have reactions to preservatives, fragrances, topical anesthetics and topical corticosteroids evaluated.
