Overview
Allergic contact dermatitis is a type of skin rash that occurs when your skin comes into contact with a substance that triggers an allergic reaction. It is a delayed hypersensitivity reaction that typically develops 48 to 72 hours after exposure to the allergen.
Allergic contact dermatitis can be caused by a wide range of substances, including:
- Metals like nickel, gold and silver
- Fragrances and perfumes
- Cosmetics and personal care products
- Soaps and detergents
- Poison ivy, oak and sumac
- Latex
Symptoms of allergic contact dermatitis can vary depending on the severity of the reaction and the location of the rash. Common symptoms include:
- Redness, itching and swelling
- Blisters or bumps that ooze or crust over
- Dry, scaly or cracked skin
- Burning or stinging sensation
- In severe cases, the skin may become thickened, discoloured, or develop deep cracks
