Many people believe that their acne is influenced by dietary factors, which is ironic because up until the past decade or two, doctors thought that diet had little influence on acne developing. There is little concrete and testable scientific evidence to support or refute diet as a cause of acne. Most doctors will tell concerned patients to keep a healthy diet, exercise, and use acne products that are sensitive enough to use on a daily basis without drying out the skin. There are also certain acne treatment lotions that are designed to be used even when your skin is acne free because they will not aggravate the skin or clog pores.
