Which symptom is commonly associated with irritant contact dermatitis?

Redness, swelling, and scaling are classic symptoms associated with irritant contact dermatitis. This condition occurs when the skin comes into contact with a substance that causes irritation, leading to an inflammatory response. The redness is indicative of increased blood flow to the affected area, while swelling is a result of the body's immune response. Scaling often occurs as the skin tries to recover from the irritation, shedding dead skin cells in the process.

Popping blisters is more closely related to allergic contact dermatitis or other more severe skin reactions, while itching and dryness can also be seen in various skin conditions but are not as defining for irritant contact dermatitis as redness and scaling. Dark pigmentation typically results from chronic irritation or inflammation rather than being a direct symptom of irritant contact dermatitis.
