What are the symptoms of contact dermatitis?

The symptoms of contact dermatitis are primarily characterized by redness, swelling, and peeling skin. This condition occurs as a direct result of exposure to an irritant or allergen, leading to an inflammatory response in the skin.

Redness indicates that the blood vessels in the area are dilating, which is a natural reaction to inflammation. Swelling occurs as a result of increased fluid in the tissues, and peeling skin is often a sign of the skin's barrier becoming compromised. These symptoms reflect the body's defense mechanism trying to manage and heal from the irritation or allergic reaction, making them prominent features of contact dermatitis.

Itching and dryness may occur as a secondary response but are not the primary symptoms. Similarly, while pain and swelling can accompany many skin conditions, the definitive symptoms of contact dermatitis are more accurately represented by redness, swelling, and peeling skin. Discoloration and thickening may result from chronic irritation over time but do not define the immediate reaction seen with contact dermatitis.
