Body dysmorphic disorder: 

• A psychiatric disorder characterized by excessive preoccupation with imagined defects in physical appearance.
•  People with body dysmorphic disorder (BDD) are obsessed by the idea that some part of their body — their hair, nose, skin, hips, whatever — is ugly or deformed, when in truth it looks normal.
•  BDD may focus on moles, freckles, acne, minor scars, facial or body hair, or the size and shape of their breasts or genitalia. 
• People with BDD may spend an excess of time looking in the mirror, be forever fixing their hair, or wear heavy makeup or sunglasses inside as a form of camouflage.
• They may make multiple medical visits or have surgical procedures to correct the imagined defect. 
• Treatment of BDD may involve cognitive behavioral therapy or medications, usually those used in obsessive-compulsive disorder to which BDD may be related. 
• BDD is also called somatoform disorder, dysmorphophobia.
