Body Dysmorphic Disorder

Body Dysmorphic Disorder (BDD) is a mental health condition where an individual is excessively concerned about a perceived flaw in their physical appearance. This flaw, in reality, may be either nonexistent or barely noticeable to others. Individuals with BDD often engage in repetitive behaviors such as mirror checking, skin picking, and seeking reassurance to cope with their distress.
