Excoriation (Skin-Picking) Disorder, also known as Dermatillomania, is a mental health condition characterized by the compulsive urge to pick at one's own skin, often to the point of causing damage. It's classified as a type of Body-Focused Repetitive Behavior (BFRB), similar to other behaviors like hair-pulling (trichotillomania).
