What is a common symptom of contact dermatitis?

A common symptom of contact dermatitis is red, itchy skin. This condition occurs when the skin comes into contact with an irritant or allergen, leading to an inflammatory reaction. The inflammation often manifests as redness due to increased blood flow to the affected area, which is a typical response of the immune system. Itching accompanies this reaction as the skin's nerve endings become more sensitive due to the irritation.

While symptoms like dryness, flakiness, and blisters can also occur in some cases of contact dermatitis, the hallmark symptoms are red and itchy skin. This combination is crucial for identifying contact dermatitis and differentiating it from other skin conditions. Understanding these primary symptoms aids cosmetology professionals in recognizing skin issues and advising clients accordingly, ensuring they receive the proper care and treatment necessary.
