Excoriation Disorder is characterized by a repeated urge to pick at one's own skin. It is a psychological condition that can cause skin damage and is often compulsive, requiring treatment like cognitive behavioral therapy.
Step-by-step explanation:
Excoriation Disorder is described as A: Repeated urge to pick at one's own skin. It is a condition recognized by mental health professionals in which an individual has an uncontrollable urge to scratch, pick, or dig at their skin, often leading to damage and harm. This disorder is one of several Body-Focused Repetitive Behaviors (BFRBs), which also includes conditions like trichotillomania, the recurrent pulling of one's hair (C).
While skin disorders such as eczema and acne involve the inflammation or clogging of pores, respectively, and are largely physiological, Excoriation Disorder has a psychological component where the behavior becomes compulsive. The condition can result in significant distress or impairment, socially, occupationally, or in other important areas of functioning. Treatment approaches often involve cognitive behavioral therapy and may include efforts to address both the psychological triggers and the physical skin symptoms.
