Excoriation Disorder

Excoriation disorder is a mental disorder characterized by the repeated urge to pick at one's own skin, often to the extent that significant skin damage is caused.


Prevalence is 1-2% in the general population. It affects significantly more females than males. There is a high comorbidity with OCD, trichotillomania, depression, body dysmorphia, and tics.

Similar to other OCD-related disorders, SSRIs may be helpful for compulsive skin picking but with limited effects. N-acetylcysteine and naltrexone have more robust effects, though habit reversal training remains the main treatment with such individuals.
