Accompanying Disorders
Individuals with dermatophagia may also display symptoms of excoriation disorder, which involves compulsive and repetitive picking and rubbing of the skin. Excoriation disorder affects a significant portion of the general population, ranging from 1.4% to 5.4%, leading to noticeable damage to the tissue. In addition, nail biting, known as onychophagia, is another body-focused repetitive behavior (BFRB) that often coexists with dermatophagia. Research suggests that BFRB behaviors, including dermatophagia, serve as a method of self-soothing.
Psychological Implications
Understanding the psychological implications of dermatophagia is essential in order to provide appropriate treatment and support. While the exact reasons why people develop this condition remain unknown, mental health experts concur that it is typically not indicative of underlying trauma or deep-seated psychological issues. Individuals who engage in dermatophagia often do so with the intention of improving or correcting perceived body imperfections, rather than inflicting self-harm. Additionally, this behavior may also serve as a means of alleviating boredom.
