Patients will discontinue treatment after six weeks. The co-investigator will be presented will all photograph marked with the patient letter only. He will not know the sequence of the photographs or dates taken. He will then assign a number according to his subjective evaluation of the clinical photographs, while also being blinded to which elbow or knee was treated, right or left. The scores assigned will follow the criteria listed in the investigator's Dermatitis Herpetiformis Assessment Score. The code to the photographs will be broken after the completion of photograph evaluation. Photographs of a set will be matched to those with both letter and date to determine the scores in chronological order.
