Quick answer: excoriation disorder, also called skin-picking disorder or dermatillomania, means repeated skin picking that causes visible lesions despite attempts to stop. About 2% to 3% of people have it at any time. Habit reversal training is the best-studied treatment. Evidence for medicines is limited, so a doctor should guide any prescription.
Many people pick their skin now and then. Excoriation disorder is different because the picking is repeated, hard to control and distressing. It is a recognised condition, not a lack of willpower. This guide covers what it is, how doctors diagnose it, and what the evidence says about treatment.
What Is Excoriation Disorder?
The MSD Manual defines it as recurrent picking or scratching that causes visible skin lesions. The picking is not driven by appearance or health worries. People may pick healthy skin, pimples, calluses or scabs.
Picking is often preceded by tension that it relieves. Some people pick with little awareness. Others pick in a more focused way. It often starts in adolescence, though it can begin at any age, and roughly 60% to 75% of those affected are female.
It belongs to the body-focused repetitive behaviours, alongside hair pulling and nail biting. In DSM-5-TR it sits under obsessive-compulsive and related disorders. It often co-occurs with obsessive-compulsive disorder and depression.
Signs and Diagnosis of Excoriation Disorder
Diagnosis needs four things, according to the MSD Manual. There must be visible lesions from recurrent picking. There must be repeated attempts to cut down or stop. The picking must cause significant distress or impair daily life. It must not be better explained by a substance, another medical condition such as scabies, or another mental disorder.
Shame often leads to hiding the skin and avoiding social events. People usually pick in private. A clinician usually combines a psychiatric assessment with a general medical check.
Why Do People Pick Their Skin?
Tension relief is the pattern clinicians describe most. A minor spot, scab or rash can also start a cycle. Picking delays healing and adds itch, which prompts more picking. Rituals can include hunting for specific scabs or pulling them a particular way.
Excoriation Disorder Treatment: What the Evidence Shows
| Option | Evidence |
|---|---|
| Habit reversal training | Best-studied therapy and treatment of choice. Includes awareness training, stimulus control and competing responses. |
| N-acetylcysteine or memantine | Small randomised trials showed more symptom reduction than placebo. Increasingly considered first-line. |
| SSRIs or clomipramine | Sometimes used, especially with depression or anxiety. Evidence for reducing picking itself is limited. |
Habit reversal works in three parts. Awareness training helps you notice when and where picking starts. Stimulus control changes the setting, for example by covering a mirror or keeping nails short. Competing response training gives your hands a different action when the urge appears.
Medicine choices belong to a prescriber. Rules on which medicines are licensed for this condition vary by country, so ask your doctor about the status where you live.
Evidence Table: Common Claims
| Claim you may see | Where it stands |
|---|---|
| SSRIs are the best-researched treatment | Overstated. Habit reversal is best studied; SSRI evidence for picking is limited. |
| Excoriation disorder is just a bad habit | Not supported. It is a recognised psychiatric condition. |
| Aloe vera or coconut oil treats it | Not supported by the sources reviewed. They may soothe skin but do not treat the disorder. |
| It is not serious | Overstated. Severe cases cause scarring, infection and heavy bleeding. |
| Covering mirrors and removing tools can help | Consistent with stimulus control, a part of habit reversal. |
Safety: Wounds, Infection and Support
Open wounds can become infected. See a doctor for hot, swollen or increasingly painful skin, pus, fever, or bleeding that will not stop. The MSD Manual lists scarring, infection and sepsis as complications of severe cases.
Picking often comes with shame and low mood. If you feel hopeless or have thoughts of harming yourself, contact a doctor or your local emergency or crisis service straight away. Support from a therapist trained in habit reversal can make a real difference.
A condition of recurrent skin picking that causes visible lesions despite attempts to stop, and that causes distress or impairs daily life.
About 2% to 3% of people have it at any given time. Roughly 60% to 75% of those affected are female.
The exact cause is unclear. Picking is often preceded by tension that it relieves. A minor scab or spot can also start a cycle of picking, itch and delayed healing.
By a clinician using DSM-5-TR criteria, plus a medical check to rule out other causes such as scabies or substance effects.
Habit reversal training, a form of cognitive behavioural therapy, is the best-studied treatment. It includes awareness training, stimulus control and competing response training.
Possibly. N-acetylcysteine and memantine showed benefit in small trials. SSRIs have limited evidence for picking itself. A doctor should guide any medicine.
It is grouped with obsessive-compulsive and related disorders and often co-occurs with OCD and depression, but picking is not driven by obsessions about appearance.
If you cannot stop, if it causes distress or scarring, or if wounds show signs of infection such as heat, swelling, pus or fever.
