The purpose

This study is to see if there's any difference in the amount of facial irritation when two acne products are used together on one side of the face, compared to one acne treatment product used alone on the other side of the face. All people participating in this trial will be required to return to the same study center every weekday for two weeks for the investigator to check for irritation on the face and to have the products applied - on weekends they will have to put them on at home. If one side of the face is more irritated than the other side, a picture will be taken as well.
