Clinical trial eligibility criteria: eligible ages (years): 16.0-29.0,  Acne Vulgaris Capable of understanding and willing to provide signed and dated written voluntary informed consent (and any local or national authorization requirements) before any protocol specific procedures are performed. 2. Male or female aged from 16 to 29 years, inclusive, at time of consent. No more than 50% of the subjects at each site can be enrolled under the age of 20. 3. Mild facial acne, characterized by at least 12 facial inflammatory lesions (papules and pustules) and/or noninflammatory lesions (open and closed comedones) on each half of the face (excluding nose and front hairline areas). 4. Able to complete the study and to comply with study instructions. 5. Sexually active females of childbearing potential participating in the study must agree to use a medically acceptable method of contraception while receiving protocol-assigned product. A woman of childbearing potential is defined as one who is biologically capable of becoming pregnant; including perimenopausal women who are less than 2 years from their last menses. Acceptable contraceptive methods the following Hormonal contraception, including oral, injectable, or implantable methods started at least 2 months prior to screening. If hormonal contraception was started less than 2 months prior to screening, then a form of nonhormonal contraception should be added until the third continuous month of hormonal contraception has been completed Two forms of reliable nonhormonal contraception, to the use of either an intrauterine device plus a reliable barrier method or 2 reliable barrier methods. Reliable barrier methods condoms or diaphragms. A cervical cap is also a reliable barrier method, provided that the female subject has never given birth naturally. The combined use of a condom and spermicide constitute 2 forms of acceptable nonhormonal contraception, provided that they are both used properly. The use of spermicide alone and the improper use of condoms are inferior methods of contraception.
