Excoriation Disorder

Excoriation disorder is a mental health condition that manifests through the compulsive urge to pick at one’s own skin. While a natural grooming behavior, 2-5% population struggles with skin picking to various degrees. It falls under the umbrella term body-focused repetitive behaviors (BRFBs), which includes trichotillomania, rhinotillexomania, and scab eating disorder.

In May of 2013, excoriation disorder was added to the fifth edition of the Diagnostic and Statistics Manual of Mental Health Disorders under the Obsessive-Compulsive and Related Disorders category. Before it’s inclusion in the DSM 5, excoriation disorder was known as dermatillomania, psychogenic or neurotic excoriation, acne excoriee, and compulsive, chronic, or pathological skin picking.

Excoriation Disorder

Diagnostic criteria for excoriation disorder include: 1

  1. Recurrent skin picking that results in skin lesions
  2. Repeated attempts to stop the behavior
  3. The symptoms cause clinically significant distress or impairment
  4. The symptoms are not caused by a substance or medical, or dermatological condition
  5. The symptoms are not better explained by another psychiatric disorder

Skin picking can occur automatically, subconsciously, or during sleep. People with excoriation disorder often go into a trance-like state where they become preoccupied with removing real or perceived imperfections. The need to pick at one’s skin creates anxiety, which is alleviated after engaging in the behavior but often creates distress due to the visible marks left behind.

Individuals with excoriation disorder experience social anxiety from the embarrassment and shame of their appearance or inability to manage the urge. It may become isolating, as they may avoid situations where their marks are exposed. Compulsive skin picking can be a time-consuming behavior, with people often trying to hide damage with clothing and/ or makeup. Skin pickers are more likely to experience depression, low self-esteem, and poor body-image because of how encompassing this disorder is.

Excoriation disorder can be a co-morbidity with (but not limited to) other BFRBs, depressive disorders, anxiety disorders, personality disorders, ADHD, and body dysmorphia. It can manifest in individuals with neuro-cognitive disorders (ie, alzheimers) and those who are developmentally disabled. Skin picking may also present as a tic disorder (ie, tourette’s syndrome) or serve as a stim for those on the autism spectrum.

Often mischaracterized as a self-harming behavior, most skin pickers do not intentionally cause damage; they want to “fix” an imperfection, and lesions are the undesired consequences of relieving the urge.

Excoriation disorder is still not universally known in the general public, or within the medical profession. More awareness for excoriation disorder and other BFRBs is needed to eliminate shame and stigma while reducing
