Acne is a common inflammatory skin condition characterized by skin eruptions around hair follicles. People with acne can have pustules (zits or pimples), papules, whiteheads or blackheads, nodules, and redness of the skin. Acne usually involves the face and shoulders, but can also involve the chest, arms, and legs. The purpose of this study is to evaluate the safety and effectiveness of an investigational gel containing active medication compared to the same gel without any active medication (placebo or vehicle) in subjects with mild to moderate facial acne.
