- Substances that react to sunlight like sunscreen (photoallergic contact dermatitis)
- Nickel in jewelry or coins, cosmetics, nail polish, and deodorant
- Products containing Balsam of Peru and/or formaldehyde
Symptoms and Risk Factors
The symptoms of contact dermatitis can occur immediately or within hours after the skin makes direct contact with an allergen or irritant. As a result, manifestations of this condition usually appear on the exposed areas of the skin.
Usually, the signs and symptoms to look out for are itchy, cracked, dry, or blistered skin accompanied by a red rash and/or blisters that may ooze clear fluid. However, darker skin tones may have rashes that are gray, purple, or dark brown.
While contact dermatitis can occur on any part of the body, it usually affects the hands or the face. This is due to the fact that these are the parts of the body that are almost always exposed.
Risk Factors of Contact Dermatitis
Some people are more at risk of developing contact dermatitis, especially if their workplace requires frequent contact with irritants or allergens:
- Chefs and other people who work in the food industry
- Health care professionals
- People who work in metalworking, construction, or agriculture
- Professional cleaners, mechanics, cosmetologists, and hairdressers
