Scientology Spots: Snarky rumors swirled in May when a love-struck Katie Holmes was photographed with what looked like a swarm of cold sores on her face. But could the culprit have actually been Scientology and not a “social disease”? A “celebrity watchdog” group reports that the spots are consistent with “the nasty side effects of a Church of Scientology ‘detoxification’ procedure involving the vitamin niacin,” which Scientology founder L. Ron Hubbard recommends “along with exercise and sauna sessions” to “help purge the body of ‘radiation,’ his shorthand for negative alien substances in the body.” Called “Purif” by devotees, the process makes “liberal use of the B-complex vitamin, which is used in traditional medicine to decrease cholesterol and improve circulation and can cause a red flush on the face and a diffuse itchy rash on the body when taken in large doses.” A New York City dermatologist, though, has his doubts. “Although I can’t say for sure, this looks like a cold-sore attack,” says Dr. Paul Frank. “Niacin shouldn’t trigger cold sores. [But] stress is the No. 1 cause,” adding “God knows Scientology stresses me out!” (NYDN, Lowdown, Defamer)
