Rosacea is a common dermatological condition, for which no therapy is 100% effective. Evaluations generally compare one type of treatment with controls.1,2 Little information comparing alternative forms of treatment for rosacea is available. One of the issues in evaluating different approaches to managing the disease is the subjectivity involved in grading signs and symptoms. This problem is compounded by the use of different observers in grading the severity of rosacea.
