Dermatophagia is an emerging concept in mental health research. For this reason, there have been few studies into precisely what it is and how it differs from other conditions.
According to the TLC Foundation for Body-Focused Repetitive Behaviors, mental health specialists sometimes classify dermatophagia as an “obsessive-compulsive and related disorder.”
This means that it is related to or part of obsessive-compulsive disorder (OCD). With this condition, a person has ongoing, uncontrollable, and recurring thoughts and behaviors.
