The region most commonly picked is the face, but other frequent locations include the arms, legs, back, gums, neck, shoulders, scalp, abdomen, chest, and extremities such as the fingernails, cuticles, and toenails. Most patients with excoriation disorder report having a primary area of the body that they focus their picking on, but they will often move to other areas of the body to allow their primary picking area to heal. Individuals with excoriation disorder vary in their picking behaviour; some do it briefly multiple times a day while others can do one picking session that can last for hours. The most common way to pick is to use the fingers although a significant minority of people use tools such as tweezers or needles.
