Dermatillomania, clinically known as excoriation disorder, affects roughly 3.5% of the general population based on a systematic review and meta-analysis of available studies. That makes it more common than many people realize, putting it in the same ballpark as conditions like OCD. A large U.S. survey of over 10,000 adults found that 2.1% had current skin picking disorder and 3.1% had experienced it at some point in their lives.
How Prevalence Estimates Vary
The numbers shift depending on how strictly the condition is defined and who’s being studied. The 3.5% pooled estimate comes from combining data across multiple studies and populations. The 2.1% figure for current cases in a U.S. sample represents people actively experiencing the disorder at the time they were surveyed, while the 3.1% lifetime figure includes people who had it in the past but no longer do.
No large-scale national epidemiological study has been conducted specifically for skin picking disorder, so all current estimates come from smaller surveys, convenience samples, and meta-analyses that pool those results together. The true number could be higher, partly because many people with the condition never seek help. Less than one in five people with skin picking disorder are estimated to pursue treatment, and those who do often see a general practitioner or dermatologist rather than a mental health professional. That means the condition flies under the radar in clinical settings.
Who It Affects Most
Women are significantly more likely to develop dermatillomania than men. Meta-analytic data puts the female-to-male ratio at about 1.45 to 1, meaning for roughly every 10 men with the condition, about 14 or 15 women have it. This gender split is similar to what’s seen in trichotillomania (compulsive hair pulling), which has a female-to-male ratio of about 1.3 to 1. Both fall under the umbrella of body-focused repetitive behaviors.
In the U.S. survey, the gender balance among those with current skin picking disorder was 55.4% female and 44.6% male, consistent with the broader meta-analytic findings.
Typical Age of Onset
Skin picking disorder can start at any age, but it overwhelmingly begins in adolescence. A study that analyzed age-of-onset patterns found two distinct groups. The larger group, making up 93% of people with the condition, started picking at an average age of 13.6 years. A much smaller group, about 7%, developed it in middle adulthood with an average onset around age 42.8 years.
The adolescent onset makes sense given that puberty is a time of increased skin changes, heightened self-consciousness, and shifting emotional regulation. Researchers have suggested that whether picking begins before or after puberty may represent meaningfully different subtypes of the condition, though that distinction is still being explored clinically.
The Line Between Picking and a Disorder
Occasional skin picking is extremely common. Most people pick at a scab, a hangnail, or a blemish from time to time. What separates dermatillomania from normal behavior is a specific set of criteria. The picking has to be recurrent and result in visible skin lesions. The person has to have tried repeatedly to stop or cut back. And the behavior has to cause real distress or get in the way of social life, work, or daily functioning.
The diagnosis also rules out picking that’s driven by substance use, a medical skin condition, or another mental health disorder like psychosis or body dysmorphic disorder. This means the 2 to 3.5% prevalence figures represent people whose picking is persistent, distressing, and not better explained by something else. The number of people who pick their skin regularly but don’t quite meet all the criteria is almost certainly much larger.
Conditions That Overlap With It
Dermatillomania rarely shows up alone. The U.S. prevalence study described high rates of comorbidity as a hallmark of the condition. Mood disorders are especially common: among people with both body dysmorphic disorder and skin picking, nearly 85% also had a mood disorder like depression. People with skin picking were also more likely to have a personality disorder (57% versus 39% in those without picking) and more likely to have trichotillomania (6.3% versus 0%).
The relationship between skin picking and body dysmorphic disorder is particularly notable. In a study of 176 people with body dysmorphic disorder, nearly 45% reported skin picking at some point in their lives, and 37% were currently picking. This overlap makes clinical sense: when someone is intensely focused on perceived flaws in their appearance, picking at skin imperfections can become a compulsive attempt to “fix” what they see.
Why It Stays Hidden
Despite affecting millions of people, dermatillomania remains widely underdiagnosed. It was only added to the main diagnostic manual as its own disorder in 2013, when the DSM-5 placed it alongside OCD and related conditions. Before that, it lacked a formal diagnostic home, which meant clinicians weren’t systematically screening for it.
Shame plays a major role in keeping the condition invisible. People often hide the physical evidence with clothing or makeup and avoid situations where their skin might be seen. With fewer than 20% seeking treatment, the gap between how many people have dermatillomania and how many get help for it is enormous. Many people live with it for years, sometimes decades, without knowing it has a name or that effective treatments exist.
