Paul was a 26-year-old white British man who sustained 8% TBSA mixed-depth burns to his face and hands during a workplace welding accident 13 months before the intervention. He had been working full-time in the welding industry before the accident and lived with his partner and pre-school daughter. He had no history of psychological difficulties. After the accident, Paul developed PTSD, which had been treated successfully through trauma-focused psychological therapy by the second author (AT). Before the intervention for his appearance anxiety, Paul's symptoms of PTSD were in the subclinical range and not impacting upon any area of his life. Paul experienced appearance anxiety associated with scarring on his hands and pigmentation changes to his face. He was troubled by thoughts about others judging him negatively and worried others would ask questions and that he would not be able to manage social exchanges. He spent excessive amounts of time checking and concealing his scarring by clothing, gloves and make-up. He was isolating himself, avoiding public places and had stopped doing meaningful activities with his young daughter, such as taking her to nursery, swimming and dance lessons. Paul received nine sessions of ACT. He cancelled and rearranged four sessions and had no non-attendances.
