OCD-related conditions
Skin-picking disorder (dermatillomania)
Skin-picking disorder involves recurrent picking that is difficult to stop and can damage the skin. HRT and ComB address both automatic and focused patterns.
Typical concerns and behaviours
Typical concerns or triggers
- Attention to bumps, scabs or the texture of the skin
- An urge to make the skin smooth, clean or complete
- Shame and fear that skin damage will be noticed
Typical behaviours and strategies
- Picking, scratching, squeezing or rubbing the skin
- Searching for and examining particular areas with the fingers or a mirror
- Removing scabs, flakes of skin, spots or irregularities
- Concealing skin damage and avoiding situations in which it may be seen
Skin picking may begin with a small bump, a loose piece of skin or a scab that the fingers keep returning to. Some people deliberately search for something they want to remove. For others, a hand moves across the skin automatically while they read, use a screen or talk to someone. When the picking recurs, causes wounds and is difficult to stop, the pattern may be skin-picking disorder, also known as dermatillomania or excoriation disorder.
What is skin-picking disorder?
Skin-picking disorder involves repeatedly picking, scratching, squeezing, rubbing or biting the skin. The action may be directed at healthy skin, but often begins with something that can be seen or felt: a spot, a scab, a hair follicle, dry skin or a small irregularity. The area may then be examined and picked at until the skin is sore or broken.
The diagnostic term is excoriation (skin-picking) disorder. Dermatillomania, skin-picking disorder and compulsive skin picking are also widely used. Together with trichotillomania, it is grouped among the body-focused repetitive behaviours, often abbreviated to BFRBs.
The repeated picking damages the skin and continues despite attempts to stop. It may lead to pain, considerable time lost to picking, shame, concealment, avoidance or conflict. Even a small affected area around the lips, cuticles or face can have a substantial effect on daily life.
Automatic and focused skin picking
Skin picking is often described as automatic, focused or a mixture of the two. The same person may move between them, even during a single episode.
Automatic skin picking often takes place without full awareness. The fingers search the scalp, arms, face or cuticles while the person watches television, reads, talks on the phone or lies in bed. The movement may be so habitual that it is noticed only when the skin hurts or a scab is found between the fingers.
Focused skin picking is more deliberate. The person searches for a particular bump, spot, pore, scab or loose piece of skin and continues until the area feels smooth, clean or complete. Bright lighting, a magnifying mirror or feeling the skin with the fingertips may draw attention to minute irregularities. An episode may begin with the intention of removing just one thing, then continue because the first action creates a new edge or wound that also seems to need attention.
An episode may begin automatically and become focused when the fingers find an irregularity. What starts the episode and what makes it difficult to end may therefore be different.
What keeps the pattern going?
A scab may feel rough, a pore may look dark, or an area may itch, tingle or feel tight. Once the fingers start checking, they often discover more irregularities. Picking can briefly provide relief, stimulation or a sense that the area has become smooth and complete.
The thoughts may be brief and convincing: I’ll just remove this one. It will heal better if I get it out. I’ll stop as soon as the area is smooth. In the moment, they can make it seem reasonable to continue.
Stress, irritation and restlessness increase the urge for some people. Others pick most when they are bored, tired, concentrating or at rest. A quiet evening in front of the television may therefore be more difficult than a busy day.
Particular movements and settings may gradually begin to trigger picking: resting an elbow on the table, having one hand free, leaning close to a mirror or running the fingers over the skin after a shower. Treatment addresses both the sensations and emotions involved and the chain of events that leads from a situation to picking.
When healing becomes part of the pattern
Acne, eczema, dryness, insect bites, scars and healing wounds can provide something tangible to see or feel. The original skin concern becomes the starting point, while repeated touching and picking keep the pattern going.
As the skin heals, a scab, hard edge or itch develops. Removing the scab to make the skin even starts the healing process again and creates another opportunity to pick. This cycle can continue after the original spot or irregularity has gone.
A simple skincare plan can reduce dryness, itching and wounds. Extensive inspections, squeezing and frequently changing products can instead become part of the sequence. Skincare is most helpful when it supports healing without prompting further searching and picking.
Infection, persistent bleeding, severe pain, deep wounds or skin changes that do not heal should be assessed by a doctor or dermatologist. Treatment of the skin can take place alongside psychological treatment.
Shame, concealment and lost time
Skin damage itself can be difficult to hide. Some people use make-up, clothing or plasters to cover affected areas. Others avoid swimming pools, sport, hairdressers, intimate relationships or social events where their skin may be visible.
The shame may also concern the loss of control. After an episode, the person may spend a long time cleaning, covering and examining the skin. From the outside, it may look like a minor habit even though picking consumes considerable time and attention.
Skin picking in different clinical patterns
Skin picking can occur as part of several clinical patterns. Understanding what prompts the action and the function it serves helps to guide treatment.
In skin-picking disorder, picking may begin automatically, be triggered by sensory details or help manage boredom, tension or restlessness.
In OCD, the person picks to neutralise doubt, avert a feared consequence or make something feel completely right. The action is then part of the OCD pattern.
In body dysmorphic disorder (BDD), the action is driven by persistent preoccupation with a perceived flaw in appearance. Mirror checking, comparison, camouflage and avoidance often occur alongside the picking.
In self-harm, the pain or injury serves a more direct function, such as self-punishment or managing intense emotions. In skin-picking disorder, damage to the skin is generally an unwanted consequence of the picking.
Treatment is adapted to the pattern driving the action. More than one pattern may be present in the same person.
Treatment for skin-picking disorder
Cognitive behavioural therapy incorporating habit reversal training (HRT) is a central treatment for skin-picking disorder. It helps the person identify the sequence from the first signal to the act of picking and practise a concrete alternative that can be used early.
Awareness training helps the person notice signals before or at the beginning of the action. These may include a hand moving towards the face, fingertips scanning the skin, a particular posture or the thought of fixing just one thing. A simple record can help reveal the pattern without becoming too burdensome to use in everyday life.
A competing response is an agreed movement that cannot be performed at the same time as picking. It is selected to fit the person’s pattern and practised until it is available when the urge or hand movement arises.
Changes to the environment make it easier to notice and interrupt picking. They may involve posture at work, lighting, mirror use, the placement of tools or planning activities for periods when the hands would otherwise be unoccupied.
Comprehensive Behavioral Treatment (ComB) looks at five areas: sensory experiences, thoughts, emotions, movements and places. This allows treatment to be tailored when some episodes are driven by sensory seeking and others arise mainly during restlessness, concentration or in particular settings.
Acceptance-based elements can help the person notice an urge or irregularity without acting on it immediately. When OCD or BDD is driving the pattern, treatment is adapted to the underlying condition. Medication may also form part of treatment following a medical assessment, alongside work on the specific behavioural sequence.
How can family and friends help?
Family and friends often respond by telling the person to stop, moving their hand away or checking their skin. Repeated reminders and attempts to intervene may increase shame, secrecy and conflict without helping the person notice the picking earlier.
It helps to agree in advance what support should look like. The person may want a neutral signal in certain situations but no comments in front of other people. Family and friends can help them remember an exercise, accompany them to a medical appointment or acknowledge when a new strategy is used. Support should strengthen the person’s own skills and participation in daily life rather than turn into inspection of the skin.
When is it relevant to seek help?
It is relevant to seek help when picking causes wounds, returns despite attempts to stop, takes up time or leads to concealment and avoidance. A clinical assessment looks at the condition of the skin, automatic and focused episodes, the situations surrounding them and the effects on daily life.
Frequently asked questions about skin-picking disorder
When is skin picking more than an ordinary habit?
Skin picking is more than an ordinary habit when it is recurrent, causes skin damage and remains difficult to reduce despite attempts to stop. Its effects may also include pain, shame, camouflage, avoidance and considerable time spent picking. The impact on daily life matters more than any fixed number of wounds or minutes.
Why is it so difficult simply to stop?
Picking can become almost automatic in response to particular sensations, movements and situations. The action may provide brief relief, stimulation or a sense that the skin has become smooth. At the same time, it creates new edges and scabs that become the next reason to pick. Willpower alone is therefore rarely enough.
Can someone pick their skin without noticing?
Yes. Automatic skin picking may occur while attention is directed towards a book, screen, conversation or work task. The person may only notice the action when the skin stings or feels sore. Treatment therefore includes practising awareness of the early hand movements and the situations in which they occur.
How does skin-picking disorder differ from OCD?
In skin-picking disorder, the action may occur automatically or be driven by sensory experiences, urges, boredom or restlessness. In OCD, it is linked to doubt, rules, a feared consequence or a need to make something feel completely right. Treatment therefore addresses different parts of the pattern.
What is the difference between skin-picking disorder and BDD?
In BDD, the picking is driven by persistent preoccupation with a perceived flaw in appearance. Mirror checking, comparison, camouflage and avoidance are often present as well. In skin-picking disorder, a spot or irregularity may be a sensory target without a broader belief that the person's appearance is wrong. The difference lies in what drives the picking and in the other symptoms present.
What does HRT involve?
Habit reversal training helps the person recognise the sequence from the first signal to the act of picking. They practise noticing early signs, using a movement that cannot be performed at the same time as picking and changing situations that set the action in motion. ComB broadens this approach by tailoring the plan to sensory experiences, thoughts, emotions, movements and places.
