What is a primary characteristic of acute dermatitis?

Acute dermatitis is characterized primarily by oozing and crusting. This condition often presents with inflammation and can cause the skin to become red, swollen, and blistered. The oozing occurs as a result of the body's immune response, which leads to fluid buildup in the affected areas. This effusion can form crusts as it dries, creating a distinct appearance that is typically associated with acute dermatitis. Recognizing this characteristic is crucial for proper diagnosis and treatment, as acute dermatitis can often be confused with other skin conditions that do not display this level of exudate.
