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.

CBT (including habit reversal, and acceptance-enhanced therapy) is first-line.[1]
