Most of us don’t think twice when we glance in the mirror. We floss our teeth, wash our faces, check our hair, and perform other quotidian tasks without getting caught in cycles of self-scrutiny and criticism. But for people with body dysmorphic disorder (BDD), catching a glimpse of oneself can be a devastating and time-consuming event. BDD acts like a funhouse mirror, rendering neutral features into striking imperfections and converting minor physical differences into grotesque disfigurements.
