EXCORIATION/ SKIN PICKING

Table of Contents

Definition of Excoriation

Excoriation refers to the act of abrading, scratching, or wearing away the skin’s surface, often resulting in a superficial wound or abrasion. In a medical context, it can also refer to a skin lesion caused by scratching or rubbing, often due to itching or irritation. Excoriations can vary in severity, from minor scratches to more significant injuries that may require medical attention. Additionally, the term can be used metaphorically to describe severe criticism or censure of someone or something.

History of Excoriation

The term “excoriation” has its roots in Latin. It comes from the Latin word “excoriatio,” which means to strip off the skin. The word is derived from “excoriare,” where “ex” means “out of” or “off,” and “corium” means “skin” or “hide.”

In a medical context, excoriation has long been used to describe injuries to the skin resulting from abrasion or scratching. Dermatologists and healthcare professionals use the term to characterize skin lesions caused by various factors, such as itching, rubbing, or other forms of irritation.

The historical understanding of excoriation in medicine has evolved along with advancements in dermatology and the study of skin conditions. Early medical texts may not have used the term in the same way it is employed today, but the concept of skin abrasion and injury has been recognized throughout the history of medicine.

In broader linguistic usage, the term excoriation can be found in literature and writings related to criticism or censure, where it metaphorically refers to the act of figuratively “stripping off the skin” through severe disapproval or condemnation.

It’s important to note that while the term has historical roots, its application and understanding in both medical and metaphorical contexts have evolved over time with advances in medical knowledge and changes in language usage.

DSM-5 Criteria of Excoriation

In the context of mental health and psychiatry, excoriation disorder, also known as dermatillomania or skin-picking disorder, is characterized by recurrent skin picking resulting in skin lesions. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), published by the American Psychiatric Association, provides criteria for the diagnosis of excoriation disorder. Below are the DSM-5 criteria:

A. Recurrent skin picking that results in skin lesions.

B. Repeated attempts to stop or decrease skin picking.

C. The skin picking causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.

D. The skin picking is not attributable to the physiological effects of a substance (e.g., cocaine) or another medical condition (e.g., scabies).

E. The skin picking is not better explained by symptoms of another mental disorder (e.g., delusions or tactile hallucinations in a psychotic disorder, attempts to improve a perceived defect or flaw in appearance in body dysmorphic disorder, stereotypes in stereotypic movement disorder, or intention to harm oneself in non-suicidal self-injury).

To be diagnosed with excoriation disorder, an individual must meet the criteria outlined in the DSM-5, and the symptoms should not be better explained by another mental disorder or a medical condition. The disorder can have a significant impact on an individual’s daily life and functioning, and seeking professional help, such as from a mental health professional, is important for assessment, diagnosis, and appropriate treatment.

Etiology of Excoriation

The etiology, or underlying causes, of excoriation disorder (also known as skin-picking disorder or dermatillomania) is not fully understood, and it likely involves a combination of genetic, biological, psychological, and environmental factors. Here are some factors that may contribute to the development of excoriation disorder:

Genetic Factors:

There may be a genetic predisposition to excoriation disorder, as it sometimes runs in families. Certain genetic factors may contribute to an individual’s susceptibility to developing compulsive skin-picking behaviors.

Neurobiological Factors:

There may be alterations in brain chemistry and neurobiological factors associated with excoriation disorder. Dysfunction in the brain’s reward system and the neurotransmitter serotonin has been implicated in some cases.

Psychological Factors:

Individuals with excoriation disorder often experience high levels of stress, anxiety, or boredom. Skin picking may serve as a coping mechanism to deal with these emotions or to provide a sense of relief.

Body-Focused Repetitive Behaviors (BFRBs):

Excoriation disorder is considered a BFRB, which also includes behaviors like hair-pulling (trichotillomania). There may be shared underlying mechanisms among BFRBs.

Perfectionism:

Some individuals with excoriation disorder exhibit perfectionistic tendencies and may focus on perceived imperfections in their skin. The urge to pick may be driven by a desire to achieve a sense of perfection.

Trauma or Abuse:

There may be a connection between excoriation disorder and a history of trauma or abuse. Skin picking might develop as a way to cope with or escape from traumatic experiences.

Environmental Factors:

Environmental stressors or life events, such as major transitions, loss, or significant changes, could contribute to the onset or exacerbation of excoriation disorder.

Sensory Factors:

Some individuals with excoriation disorder may be hypersensitive to certain sensations on the skin, making them more prone to engaging in skin-picking behaviors.

It’s important to note that the factors contributing to excoriation disorder can vary from person to person, and there is ongoing research to better understand the complex interplay of these factors. Treatment for excoriation disorder often involves a multidisciplinary approach, including cognitive-behavioral therapy (CBT), habit reversal training, and, in some cases, medication. If you or someone you know is experiencing symptoms of excoriation disorder, it’s advisable to seek the guidance of a mental health professional for a comprehensive assessment and appropriate intervention.

Theories related to Excoriation

Several psychological theories attempt to explain the development and maintenance of excoriation disorder (also known as skin-picking disorder or dermatillomania). While the exact cause is likely multifaceted and may involve a combination of factors, here are some prominent theories related to excoriation:

Cognitive-Behavioral Model:

  • The cognitive-behavioral model suggests that individuals with excoriation disorder may have specific thoughts and beliefs that contribute to their skin-picking behaviors. For example, they may engage in picking as a way to cope with negative emotions or to relieve anxiety.
  • Cognitive-behavioral therapy (CBT) for excoriation disorder often involves identifying and challenging maladaptive thoughts and implementing alternative coping strategies.

Reward and Reinforcement:

  • Some theories propose that skin-picking behaviors may be reinforced by the pleasure or relief experienced after picking. The act of picking may activate the brain’s reward system, reinforcing the behavior and making it more likely to occur again.
  • Neurobiological factors related to the reward system, such as alterations in dopamine levels, may contribute to the development and maintenance of excoriation disorder.

Sensory Processing:

  • Sensory processing theories suggest that individuals with excoriation disorder may have heightened sensitivity to sensory stimuli, including sensations on the skin. Skin picking may be a way to regulate or respond to these sensory experiences.
  • Some individuals may engage in skin picking to alleviate discomfort or tension related to sensory processing differences.

Perfectionism:

  • The perfectionism theory suggests that individuals with excoriation disorder may have perfectionistic tendencies, fixating on perceived flaws or imperfections in their skin. Skin picking may be an attempt to achieve a sense of perfection or to address feelings of inadequacy.

Emotion Regulation:

  • The emotion regulation theory posits that skin picking serves as a maladaptive coping mechanism for regulating emotions. Individuals may engage in picking to manage stress, anxiety, boredom, or other emotional states.
  • Interventions focused on improving emotion regulation skills may be incorporated into treatment approaches.

Habit Formation:

  • Excoriation disorder is classified as a body-focused repetitive behavior (BFRB), and habit formation theories emphasize the role of habit development in maintaining the behavior.
  • Habit reversal training, a therapeutic approach often used for BFRBs, aims to replace the habit of skin picking with alternative behaviors.

It’s important to recognize that these theories are not mutually exclusive, and the causes of excoriation disorder likely involve a combination of genetic, psychological, environmental, and neurobiological factors. Treatment approaches often take these various factors into account, employing a tailored and holistic approach to address the specific needs of individuals with excoriation disorder.

Risk factors of Excoriation

Several factors may contribute to an increased risk of developing excoriation disorder (also known as skin-picking disorder or dermatillomania). It’s important to note that the presence of these risk factors doesn’t guarantee the development of the disorder, but they may make individuals more vulnerable. Some common risk factors include:

Genetic Factors:

There is evidence to suggest a genetic component in the development of excoriation disorder. Individuals with a family history of skin-picking or other body-focused repetitive behaviors (BFRBs) may be at a higher risk.

Age and Gender:

Excoriation disorder often begins in adolescence or early adulthood, although it can develop at any age. The disorder appears to be more prevalent in females than in males.

Personal or Family History of Mental Health Disorders:

A history of mental health disorders, such as anxiety, depression, or obsessive-compulsive disorder (OCD), in the individual or their family may be associated with a higher risk of developing excoriation disorder.

Stress and Anxiety:

High levels of stress, anxiety, or tension may contribute to the onset or exacerbation of excoriation disorder. Skin picking may serve as a maladaptive coping mechanism to alleviate these emotional states.

Perfectionism:

Individuals with perfectionistic tendencies may be more prone to developing excoriation disorder. The desire for flawless skin and the inability to tolerate perceived imperfections may contribute to skin-picking behaviors.

Sensory Sensitivities:

Hypersensitivity to sensory stimuli, including sensations on the skin, may be a risk factor. Individuals who are more sensitive to tactile experiences may engage in skin picking as a way to regulate or respond to these sensations.

History of Trauma or Abuse:

There may be a link between a history of trauma or abuse and the development of excoriation disorder. Skin picking may emerge as a coping mechanism in response to traumatic experiences.

Body Image Concerns:

Individuals with negative body image perceptions or dissatisfaction with their physical appearance may be more prone to engage in skin picking, particularly if they perceive flaws in their skin.

Presence of Other Body-Focused Repetitive Behaviors (BFRBs):

Individuals who engage in other BFRBs, such as hair-pulling (trichotillomania), may be at an increased risk of developing excoriation disorder.

Personality Traits:

Certain personality traits, such as impulsivity or difficulty regulating emotions, may be associated with an increased risk of excoriation disorder.

It’s important to emphasize that the interaction of multiple factors, rather than a single cause, likely contributes to the development of excoriation disorder. Recognizing these risk factors can be useful in identifying individuals who may benefit from early intervention and support. If someone is exhibiting symptoms of excoriation disorder, seeking the guidance of a mental health professional is advisable for a comprehensive assessment and appropriate care.

Treatment of Excoriation

The treatment of excoriation disorder (also known as skin-picking disorder or dermatillomania) typically involves a combination of therapeutic approaches, including behavioral interventions, psychotherapy, and sometimes medication. Here are some common components of the treatment process:

Cognitive-Behavioral Therapy (CBT):

CBT is often considered the most effective therapeutic approach for excoriation disorder. The focus is on identifying and modifying the thoughts and behaviors associated with skin picking. Cognitive restructuring helps individuals challenge and change maladaptive thought patterns related to their picking behavior.

Habit Reversal Training (HRT):

HRT is a specific form of behavioral therapy designed to replace the habit of skin picking with alternative, incompatible behaviors. Individuals learn to identify triggers for picking, develop awareness of the behavior, and engage in a competing response that prevents picking.

Mindfulness-Based Interventions:

Mindfulness techniques, such as mindfulness meditation and acceptance and commitment therapy (ACT), can help individuals increase awareness of their thoughts and emotions without judgment. Mindfulness may be integrated into treatment to enhance self-regulation and reduce impulsivity.

Exposure and Response Prevention (ERP):

ERP, commonly used in the treatment of obsessive-compulsive disorder (OCD), involves exposing individuals to situations that trigger the urge to pick and preventing the picking response. Over time, this can help reduce the intensity of the urge and the frequency of the behavior.

Psychopharmacological Interventions:

In some cases, medication may be considered, especially if there is a co-occurring mental health condition such as anxiety or depression. Selective serotonin reuptake inhibitors (SSRIs) are among the medications that may be prescribed, as they can help regulate serotonin levels in the brain.

Support Groups:

Participating in support groups or therapy groups with individuals who share similar challenges can provide a sense of community, understanding, and encouragement. Sharing experiences and coping strategies can be beneficial.

Individual Therapy:

Individual therapy sessions with a mental health professional, such as a psychologist or counselor, can provide personalized support and address underlying issues contributing to the skin-picking behavior.

Educational and Psychoeducational Approaches:

Providing education about excoriation disorder, its triggers, and coping strategies can empower individuals to better understand and manage their condition.

Self-Help Strategies:

Encouraging the development of self-help strategies, such as maintaining a journal to track picking episodes, using fidget tools to keep hands occupied, and implementing relaxation techniques, can be beneficial.

Treatment plans are often individualized based on the specific needs and circumstances of the person with excoriation disorder. It’s essential for individuals experiencing symptoms of excoriation disorder to seek professional help for a comprehensive assessment and to develop an appropriate treatment plan. Treatment success may require time, persistence, and collaboration between the individual and their healthcare providers.

Therapies for Excoriation

Several therapeutic approaches can be effective in addressing excoriation disorder (also known as skin-picking disorder or dermatillomania). These therapies aim to target the underlying psychological and behavioral aspects of the condition. Here are some common therapeutic interventions for excoriation disorder:

Cognitive-Behavioral Therapy (CBT):

CBT is one of the most widely used and researched therapeutic approaches for excoriation disorder. It focuses on identifying and modifying the thoughts and behaviors associated with skin picking. CBT helps individuals develop coping strategies, challenge irrational thoughts, and learn alternative responses to triggers.

Habit Reversal Training (HRT):

HRT is a specific behavioral therapy that aims to replace the habit of skin picking with a competing response. Individuals learn to identify situations that trigger picking, develop awareness of the behavior, and practice engaging in an alternative behavior that is incompatible with picking.

Acceptance and Commitment Therapy (ACT):

ACT combines mindfulness and behavioral strategies to help individuals accept their thoughts and feelings without judgment while committing to behavioral changes aligned with their values. It can be beneficial in addressing the emotional aspects of skin picking.

Mindfulness-Based Interventions:

Mindfulness techniques, such as mindfulness meditation, encourage individuals to be present in the moment without judgment. Mindfulness can help increase awareness of triggers, sensations, and emotions associated with skin picking, allowing individuals to respond more skillfully.

Exposure and Response Prevention (ERP):

ERP, commonly used in the treatment of obsessive-compulsive disorder (OCD), involves exposing individuals to situations that trigger the urge to pick and preventing the picking response. Over time, this can lead to habituation and reduced anxiety associated with not engaging in the behavior.

Dialectical Behavior Therapy (DBT):

DBT incorporates cognitive-behavioral and mindfulness strategies. It is particularly useful for individuals who struggle with emotion regulation. DBT skills training can help individuals develop healthier ways to cope with stress and intense emotions.

Psychodynamic Therapy:

Psychodynamic therapy explores unconscious thoughts and emotions that may contribute to skin-picking behavior. It aims to help individuals gain insight into underlying issues and develop healthier ways of coping.

Group Therapy:

Group therapy provides a supportive environment where individuals can share their experiences, challenges, and successes with others facing similar struggles. It can offer a sense of community and reduce feelings of isolation.

Family Therapy:

In some cases, involving family members in therapy can be beneficial, especially if there are family dynamics or interpersonal issues contributing to the skin-picking behavior.

Pharmacotherapy:

While therapy is often the primary intervention, medications may be considered in cases where co-occurring conditions such as anxiety or depression are present. Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed.

It’s important to note that the effectiveness of therapies may vary among individuals, and a combination of approaches may be utilized based on the specific needs of the person with excoriation disorder. Seeking the guidance of a mental health professional is crucial for a thorough assessment and the development of an appropriate treatment plan.

Preventions of Excoriation

Preventing or managing excoriation disorder (skin-picking disorder) involves a combination of strategies aimed at addressing the underlying triggers, promoting healthy coping mechanisms, and minimizing the occurrence of skin-picking behaviors. Here are some preventive measures and strategies:

Awareness and Education:

Education about excoriation disorder is crucial for both individuals affected by the condition and those around them. Understanding the disorder, its triggers, and the impact it can have fosters empathy and support.

Identifying Triggers:

Recognizing specific triggers that lead to skin-picking episodes is an essential step in prevention. Common triggers include stress, anxiety, boredom, and certain environmental factors. Keeping a journal to track triggers can be helpful.

Cognitive-Behavioral Strategies:

Learning and practicing cognitive-behavioral strategies can help individuals challenge and modify thoughts and behaviors associated with skin picking. Techniques such as cognitive restructuring can be effective.

Habit Reversal Training (HRT):

HRT involves developing awareness of skin-picking triggers and practicing alternative behaviors that are incompatible with picking. Engaging in competing responses helps break the habit of skin picking.

Mindfulness and Relaxation Techniques:

Mindfulness-based interventions and relaxation techniques, such as deep breathing and progressive muscle relaxation, can be effective in reducing stress and anxiety, which are common triggers for skin picking.

Environmental Modifications:

Making changes in the environment to minimize triggers can be beneficial. This may include keeping the skin moisturized to reduce the sensation of dryness, using fidget toys to keep hands busy, or rearranging the environment to reduce opportunities for picking.

Establishing Routines:

Creating a structured daily routine can help individuals manage stress and reduce the likelihood of boredom, both of which can contribute to skin picking. Consistent routines can provide a sense of stability.

Support Systems:

Building a strong support system is essential. Having understanding friends, family members, or support groups can provide encouragement, empathy, and assistance in maintaining positive behaviors.

Professional Help:

Seeking professional help from mental health professionals, such as psychologists or counselors, can provide guidance, support, and evidence-based interventions to address excoriation disorder.

Self-Monitoring:

Regularly monitoring and tracking skin-picking behaviors, triggers, and the emotional state surrounding the behavior can increase self-awareness and facilitate the development of targeted interventions.

Occupational Therapy:

Occupational therapy may be beneficial in developing alternative activities and coping mechanisms to redirect attention and reduce the urge to engage in skin picking.

Medication Management:

In some cases, medication, such as selective serotonin reuptake inhibitors (SSRIs), may be prescribed to help manage underlying anxiety or depression associated with skin picking.

It’s important to approach excoriation disorder comprehensively, addressing both the behavioral and emotional aspects. Individuals affected by the disorder should work closely with mental health professionals to tailor a treatment plan that suits their specific needs and circumstances.
