6. Hang Mioku
One of the most famous cases of awful plastic surgery gone wrong, Hang Mioku, a 48 year-old woman from South Korea, became so addicted to plastic surgery that she was left unrecognisable after her obsession led her to inject cooking oil into her face. She had her first plastic surgery procedure when she was 28. Following operation after operation, her face was eventually left enlarged and disfigured, and the surgeons she visited refused to carry out any more work on her and one suggested that her obsession could be a sign of a psychological disorder. So Hang resorted to injecting cooking oil into her face.
