It can affect individuals of any age, though it occurs with increased frequency and severity in older adults and in individuals with underlying dermatologic or systemic illnesses

Pathophysiologically, it results from disruption of the epidermal barrier, marked by decreased intercellular lipids—including ceramides and free fatty acids—in the stratum corneum, leading to elevated transepidermal water loss and impaired desquamation Defining clinical features include rough, dull, or scaly skin that often feels tight or pruritic and may develop erythema, fine fissures, or excoriations prone to secondary bacterial infection
