Is Dermatillomania contagious?

Dermatillomania, also known as excoriation disorder, is absolutely not contagious; it is a psychiatric condition characterized by repetitive body-focused behaviors and is not caused by any infectious agent. You cannot catch Dermatillomania through touch, social interaction, or sharing living spaces, as it arises from complex internal factors rather than pathogens.

What causes Dermatillomania?

Dermatillomania is classified as an obsessive-compulsive and related disorder. While the exact etiology remains under investigation, clinical research points to a combination of genetic predispositions, neurobiological differences in brain circuitry (specifically the cortico-striato-thalamo-cortical loops), and psychological triggers. It is not an autoimmune or degenerative disease, but rather a manifestation of emotional and neurological regulation difficulties.

Why is there confusion regarding contagion?

Because Dermatillomania often results in visible skin lesions, sores, or scarring, individuals unfamiliar with the disorder may mistakenly assume these marks are signs of a contagious skin infection. This stigma can lead to social isolation for those living with Dermatillomania. It is vital to understand that the physical damage is self-inflicted as a response to stress, anxiety, or boredom, and poses zero risk to others.

Are there environmental triggers for Dermatillomania?

While the condition is not infectious, environmental factors play a significant role in symptom management. Common triggers for Dermatillomania include:

• High levels of emotional or physical stress.


• Periods of inactivity or "down time" where the mind is under-stimulated.


• Environmental cues, such as mirrors or specific lighting, that draw attention to skin imperfections.


• Fatigue or physical discomfort, which can lower the threshold for impulse control.

Next steps

• Consult with a psychiatrist or clinical psychologist specializing in Body-Focused Repetitive Behaviors (BFRBs).


• Explore evidence-based therapies like Habit Reversal Training (HRT) or Acceptance and Commitment Therapy (ACT).


• Connect with the 260 members of the Dermatillomania community on DiseaseMaps.org for peer support and shared experiences.


• Discuss potential pharmacological interventions, such as SSRIs or N-Acetylcysteine, with your healthcare provider.
