Dermatillomania: Understanding Skin-Picking Disorder

· 7 min read

Almost everyone picks at their skin occasionally—a scab, a hangnail, a blemish. But for an estimated 2-5% of the population, skin picking becomes compulsive, damaging, and extraordinarily difficult to stop.

Dermatillomania is the clinical name for this condition. Here’s what the research says about what it is, who it affects, and what actually helps.

What Is Dermatillomania?

Dermatillomania—also known as excoriation disorder or skin-picking disorder—is a body-focused repetitive behavior (BFRB) involving recurrent picking at one’s own skin. The picking leads to skin lesions, scarring, and sometimes serious tissue damage or infection.

People pick at real or perceived imperfections: acne, scabs, calluses, insect bites, dry skin, or areas with no visible irregularity at all. The face, arms, hands, legs, and scalp are the most common sites, though any area of the body can be targeted.

The behavior uses fingernails most often, but some people use tweezers, pins, or other tools. Picking sessions can last minutes or hours, sometimes without the person realizing how much time has passed.

Clinical Classification

The DSM-5 classifies excoriation disorder under “Obsessive-Compulsive and Related Disorders,” alongside trichotillomania (hair pulling), OCD, body dysmorphic disorder, and hoarding disorder.

Diagnostic Criteria

All five must be met for diagnosis:

  1. Recurrent skin picking resulting in skin lesions
  2. Repeated attempts to decrease or stop the picking
  3. Clinically significant distress or impairment in social, occupational, or other important areas of functioning
  4. The skin picking is not attributable to the physiological effects of a substance or another medical condition (e.g., scabies)
  5. The skin picking is not better explained by symptoms of another mental disorder (e.g., delusions, tactile hallucinations, body dysmorphic disorder)

Before the DSM-5 (published in 2013), skin picking didn’t have its own diagnostic category. It was lumped under “impulse control disorder not otherwise specified.” The inclusion as a standalone diagnosis was a significant step for research, treatment, and insurance coverage.

Prevalence and Demographics

Epidemiological data on skin-picking disorder is still maturing, but current estimates indicate:

  • General population prevalence: 1.4-5.4%, depending on the study and criteria used
  • Gender: More commonly diagnosed in women (approximately 3:1 in clinical samples), though community studies suggest a less dramatic skew
  • Age of onset: Can begin at any age, but two peaks are common—early adolescence and the early 20s. Childhood onset also occurs
  • Chronicity: Without treatment, dermatillomania tends to be chronic with a waxing and waning course

Co-occurring Conditions

Dermatillomania rarely exists in isolation. Common co-occurring conditions include:

  • Major depressive disorder: 30-50% lifetime prevalence
  • Anxiety disorders: 30-45%
  • OCD: 15-25%
  • Other BFRBs (hair pulling, nail biting): 20-35%
  • Body dysmorphic disorder: 10-30%

The high co-occurrence with depression and anxiety can make it difficult to determine whether picking is a primary condition or secondary to mood symptoms. In practice, both often need to be addressed.

Focused vs. Automatic Picking

Like other BFRBs, skin picking operates along a spectrum of awareness:

Focused Picking

The person is fully aware they’re picking and may do it deliberately. Triggers include:

  • Seeing or feeling a skin irregularity
  • Intense emotional states (anxiety, frustration, anger)
  • An urge or tension that picking temporarily relieves
  • A desire for smooth or “perfect” skin

Focused picking sometimes has a trance-like quality. The person sees a blemish, intends to pick “just that one spot,” and 45 minutes later has caused far more damage than intended.

Automatic Picking

This occurs outside conscious awareness. The person may be watching TV, reading, or working on a computer and not realize they’ve been picking until they notice blood or pain. Specific postures (resting chin on hand, for example) and sedentary activities increase risk.

Most people with dermatillomania engage in both styles, and treatment strategies differ for each.

Physical Consequences

Skin picking can cause significant physical damage:

  • Scarring: Repeated picking prevents wounds from healing and creates permanent scarring
  • Infection: Open wounds are vulnerable to bacterial infection, including cellulitis and MRSA
  • Tissue damage: Chronic picking in the same area can damage deeper tissue layers
  • Disfigurement: Severe cases can cause visible disfigurement, particularly on the face
  • Medical complications: Some people require medical treatment—antibiotics, wound care, or rarely surgical intervention

The physical damage often feeds a cycle: picking creates wounds, wounds create scabs, scabs create irregularities to pick, and the cycle continues.

Social and Psychological Impact

The psychological burden of dermatillomania is often underestimated:

  • Avoidance behaviors: Wearing long sleeves in summer, avoiding swimming or intimacy, not leaving the house without makeup
  • Time consumption: Some people spend hours daily picking and then attempting to manage or hide the damage
  • Shame and secrecy: Many people hide their picking for years, even from partners and close family
  • Functional impairment: Lateness, missed social events, difficulty concentrating at work due to picking episodes or picking-related distress
  • Misunderstanding: Others may assume the person is self-harming, has a skin disease, or could simply stop if they tried harder

Treatment Options

Habit Reversal Training (HRT)

HRT is the behavioral treatment with the most evidence for skin-picking disorder. The approach includes:

  1. Awareness training: Identifying triggers, warning signs, and the sequence of behaviors that lead to picking
  2. Competing response training: Substituting an alternative behavior when the urge arises—clenching fists, handling a textured object, pressing palms flat on a surface
  3. Stimulus control: Modifying the environment to reduce picking opportunities—covering mirrors, wearing gloves, changing lighting, removing picking tools

Research shows HRT significantly reduces picking frequency and severity compared to waitlist controls, with moderate to large effect sizes.

Comprehensive Behavioral Treatment (ComB)

ComB expands on HRT by addressing picking across five functional domains:

  • Sensory: Providing alternative sensory experiences (textured objects, fidget tools)
  • Cognitive: Challenging permission-giving thoughts (“just this one spot”) and perfectionism
  • Affective: Developing emotion regulation skills for states that trigger picking
  • Motor: Building awareness of hand movements and habitual postures
  • Environmental: Restructuring settings where picking occurs (bathroom, bedroom, car)

Acceptance and Commitment Therapy (ACT)

ACT teaches people to experience picking urges without acting on them, while pursuing activities aligned with their values. Rather than fighting urges, ACT builds psychological flexibility—the ability to have uncomfortable internal experiences without being controlled by them.

Medication

No medication has FDA approval for excoriation disorder, but several have been studied:

  • N-acetylcysteine (NAC): The most promising option, with one RCT showing significant improvement at 1200-2400 mg daily
  • SSRIs: Mixed evidence for picking specifically, though they may help co-occurring anxiety and depression
  • Lamotrigine: Some positive case data but limited controlled research
  • Naltrexone: Small studies suggest benefit for some patients

Medication is typically recommended as an adjunct to behavioral therapy, not as a standalone approach.

Practical Strategies

While professional treatment provides the best outcomes, several strategies can help reduce picking day-to-day:

  • Identify high-risk situations: Track when and where picking happens. Common triggers include bathrooms (mirrors), bedtime, and idle moments
  • Reduce access to mirrors: Magnifying mirrors are particularly problematic. If you can’t remove them, cover them or set time limits
  • Keep hands occupied: Fidget tools, stress balls, textured objects near common picking locations
  • Barrier methods: Bandages over common picking sites, wearing gloves during high-risk activities
  • Skin care routine: A consistent routine can reduce the irregularities that trigger picking, but be cautious—for some people, skin care routines become picking sessions
  • Reduce isolation: Shame thrives in secrecy. Telling one trusted person can reduce the emotional burden significantly

Finding Help

Skin-picking disorder requires clinicians familiar with BFRBs. A few resources:

  • TLC Foundation for BFRBs (bfrb.org): The primary nonprofit organization for BFRB education, research, and support. Their therapist directory lists providers specializing in BFRBs.
  • Picking Me Foundation: Focused specifically on skin-picking disorder awareness and support
  • Online support groups: Reddit’s r/CompulsiveSkinPicking and the TLC Foundation’s online community connect thousands of people with shared experiences

When choosing a therapist, look for specific training in HRT or ComB for BFRBs. General CBT credentials are not enough—BFRB treatment requires specialized knowledge.
