Contact dermatitis due to fragrance in after-shave lotion
Dermatitis is a broad term used to describe inflamed skin, most often where the surface of the skin or epidermis is involved, resulting in dryness, bumpiness, blistering or peeling. Contact dermatitis is caused by a reaction to some material in direct contact with the affected area. This often results in an asymmetrical rash that crosses natural tissue boundaries. It may be acute or chronic, patchy or continuous, recurring in the same or different sites. The neck can be affected by irritant contact dermatitis to soap, perfume and fabrics (e.g., friction of a rough collar). It can also be affected by allergic contact dermatitis to nickel (in a necklace), preservatives (in a cream), resins (in nail varnish) and fragrance (in after-shave, as illustrated). If chronic or recurrent it is important to identify the cause; if necessary refer for patch testing.
The dermatitis should be managed by advising non-soap cleanser, applying moderate-potency topical steroid once or twice daily for a week or two, and emollient for symptomatic relief.
