Contact dermatitis (eczema) is an inflammation of the skin that occurs when toxic or allergens come into contact with the skin. For people who are sensitive to these substances and allergens, they can cause a skin reaction. Symptoms include itching, redness, rashes, and even, in severe cases, blisters.
The best way to avoid this type of rash is to find the responsible substance and avoid contact with it.
Contact dermatitis has 2 types: toxic and allergic contact dermatitis. Your dermatologist can determine which type and the best treatment plan for you.
