Contact dermatitis is primarily divided into two main types: irritant contact dermatitis and allergic contact dermatitis.
Allergic Contact Dermatitis
Allergic contact dermatitis is an immune-mediated hypersensitivity reaction that occurs when the skin comes into contact with a specific substance (allergen). Common allergens include metals found in jewelry (such as nickel), cosmetic products, fragrances, and preservatives. Symptoms, typically manifesting as itchy rashes, may appear several days after exposure.
Irritant Contact Dermatitis
Irritant contact dermatitis, also known as primary irritant contact dermatitis, is the most common type of contact dermatitis. It results from direct damage to the skin's protective barrier following exposure to an irritating substance. This condition is characterized by painful rashes that tend to develop rapidly after contact with the irritant. Common irritants include detergents, soaps, cleaning agents, and acids.
