[DSM-5-TR] Diagnostic Features of Excoriation (Skin-Picking Disorder)

The essential diagnostic feature of excoriation disorder is recurrent skin-picking (Criterion A), most commonly on the face, arms, and hands. Individuals may pick at healthy skin, minor irregularities, or previous scabs, often using fingernails or tools. This behavior leads to skin lesions that the individual may try to conceal.

Additionally, individuals make repeated, unsuccessful attempts to decrease or stop the picking (Criterion B). The behavior causes clinically significant distress—such as shame or a loss of control—or impairment in social, occupational, or other important functioning areas (Criterion C), sometimes consuming several hours a day.
