Excoriation Disorder (Skin-Picking Disorder)

Excoriation disorder, also called skin-picking disorder or dermatillomania, is a mental health condition in which a person repeatedly picks at their own skin, causing lesions, makes repeated attempts to stop, and experiences significant distress or impairment as a result. It is one of the body-focused repetitive behaviors (BFRBs), a group that also includes trichotillomania (hair-pulling disorder). The DSM-5 recognized it as a formal diagnosis in 2013, acknowledging what had long been dismissed as a "bad habit."

Excoriation disorder is classified in the DSM-5-TR chapter on obsessive-compulsive and related disorders, alongside OCD, body dysmorphic disorder and hoarding disorder. Many people with the condition feel deep shame and hide their picking for years, even from doctors.

DSM-5 Diagnostic Criteria

The DSM-5-TR criteria for excoriation (skin-picking) disorder (ICD-10-CM F42.4) are summarized below. Diagnosis requires assessment by a qualified professional.

1. Recurrent skin picking resulting in skin lesions.
2. Repeated attempts to decrease or stop skin picking.
3. The skin picking causes clinically significant distress or impairment in social, occupational or other important areas of functioning.
4. The picking is not attributable to the effects of a substance (such as stimulants) or another medical condition (such as scabies).
5. The picking is not better explained by symptoms of another mental disorder, such as delusions or tactile hallucinations in a psychotic disorder, attempts to improve a perceived appearance flaw in body dysmorphic disorder, stereotypies in stereotypic movement disorder, or intention to harm oneself in non-suicidal self-injury.

Distress can include feelings of loss of control, embarrassment or shame. Impairment may involve avoiding social situations, work or intimacy, or spending large amounts of time picking.

Clinical Features

Picking Patterns

Researchers describe two broad styles of picking, and most people experience both:

Picking often follows a cycle: rising tension or an urge, picking that brings a sense of relief or even satisfaction, and then regret, shame or distress at the damage. This cycle helps explain why willpower alone is rarely enough.

Common Sites

The face is the most common site, followed by arms, hands, fingers and cuticles, scalp, and the chest, shoulders and back. Picking may target healthy skin, minor irregularities, pimples, calluses or scabs from previous picking.

Related Behaviors

• Searching the skin for irregularities to pick.
• Picking with fingernails or, sometimes, tools.
• Squeezing, scratching or rubbing skin.
• Spending long periods examining skin in mirrors.
• Hiding marks with makeup, clothing or bandages.

Excoriation vs. Self-Harm vs. OCD

Distinguishing excoriation disorder from related conditions matters because the most effective treatments differ.

These conditions can also co-occur. Anyone who is harming themselves deliberately or having thoughts of suicide can find immediate support through our crisis resources.

Causes and Triggers

There is no single cause. Contributing factors include:

• Genetics: BFRBs, OCD-related conditions and anxiety are more common among relatives, and twin studies suggest moderate heritability.
• Emotion regulation: picking can soothe stress, anxiety, frustration or boredom in the short term.
• Reinforcement: the relief or satisfaction of picking acts as a reward, strengthening the habit through operant conditioning.
• Sensory factors: uneven textures, bumps or scabs can trigger an urge to "even out" the skin.
• Perfectionism: a drive for smooth, flawless skin can fuel focused picking.
• Skin conditions: acne or eczema can provide initial targets.
• Situations: being alone, sedentary, tired or in front of mirrors makes picking more likely.

Brain research suggests BFRBs may involve differences in motor inhibition, the ability to stop an action once started, and in habit-related brain circuits, though findings are still preliminary. Our page on the psychology of habits explains how habits form.

Consequences

• Physical: scarring, discoloration, open wounds and, at times, infection that needs medical care.
• Emotional: shame, guilt, low self-esteem, anxiety and depression.
• Social: avoidance of swimming, intimacy, certain clothing or social events to hide marks.
• Time: some people lose an hour or more a day to picking.
• Health care: repeated visits to dermatologists without mentioning picking, which delays effective treatment.

Treatment

Excoriation disorder responds to behavioral treatment, and recognizing it as a real condition rather than a moral failing is itself an important step. A 2016 systematic review by Madeleine Schumer, Christopher Bartley and Michael Bloch found the strongest evidence for behavioral approaches.

Habit Reversal Training (HRT)

Developed by Nathan Azrin and Gregory Nunn in 1973, habit reversal training includes:

1. Awareness training: noticing when, where and how picking happens, and the early signs of an urge.
2. Competing response: doing something physically incompatible with picking, such as clenching the fists or holding an object, until the urge passes.
3. Stimulus control: changing the environment to make picking harder, for example covering mirrors or keeping hands busy.
4. Social support: encouragement from a trusted person.

ACT-Enhanced HRT

Researchers including Douglas Woods and Michael Twohig have combined HRT with acceptance and commitment therapy. Rather than fighting urges, people learn to notice and accept them without acting, a skill related to urge surfing, and to act in line with their values. Trials suggest this combination can help people with skin picking.

Comprehensive Behavioral Treatment (ComB)

The ComB model, developed by Charles Mansueto and colleagues for BFRBs, tailors strategies to five domains that maintain picking: sensory, cognitive, affective (emotional), motor and place. For example, a person who picks while studying in bed might change study location, use a fidget toy and practice self-compassionate responses to critical thoughts.

Cognitive Behavioral Therapy

Broader CBT can address perfectionistic beliefs about skin, shame and co-occurring anxiety or depression. Group and online programs for BFRBs are also available.

Medication

No medication is approved specifically for excoriation disorder, and research results have been mixed. A doctor may discuss medication, particularly when anxiety, depression or OCD are also present, usually as an addition to behavioral treatment rather than a replacement.

Self-Help Strategies

Alongside professional support, people often find practical strategies useful:

• Using barriers such as bandages, gloves or long sleeves during high-risk times.
• Keeping hands busy with fidget objects or textured items.
• Keeping nails short.
• Reducing time with magnifying or bright mirrors.
• Tracking triggers, locations and feelings to spot patterns.
• Treating underlying skin conditions with a dermatologist.
• Responding to slips with self-compassion rather than criticism, which can reduce the shame that fuels picking.

Organizations such as the TLC Foundation for Body-Focused Repetitive Behaviors provide educational information and directories of clinicians who specialize in BFRBs.

Conclusion

Excoriation disorder is real, common and treatable. It is neither vanity nor self-harm in the usual sense, but a body-focused repetitive behavior maintained by urges, relief and habit. Habit reversal training, often combined with acceptance-based or comprehensive behavioral approaches, has the strongest evidence. Recognition and self-compassion are important early steps, because shame keeps the cycle going. Anyone struggling with skin picking can start by talking to a doctor, dermatologist or licensed therapist.
