Eligibility criteria

Inclusion Criteria:

* Male or female subjects at least 18 years of age, in good general health with documented diagnosis of facial acne vulgaris.
* 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.
* Subjects willing to follow therapeutic instructions including avoidance of any other topical facial or systemic acne therapy during the conduct of the study.
* Capable of understanding and willing to provide signed and dated written voluntary informed consent before any protocol specific procedures are performed.

Exclusion Criteria:

* Female subjects who are pregnant, trying to become pregnant or breastfeeding.
* Subjects who have any clinically relevant finding at their baseline physical examination or medical history such as severe systemic diseases, diseases of the facial skin, other than acne vulgaris.
* Facial hair that may obscure the accurate assessment of acne grade.
* History or presence of regional enteritis or inflammatory bowel disease (e.g., ulcerative colitis, pseudomembranous colitis, chronic diarrhea, or a history of antibiotic-associated colitis) or similar symptoms.
* Use of topical antibiotics on the face and systemic antibiotics within the past 2 and 4 weeks, respectively.
* Use of topical corticosteroids on the face or systemic corticosteroids within the past 4 weeks. Use of inhaled, intra-articular or intra-lesional (other than for facial acne lesions) steroids is acceptable.
* Use of systemic retinoids within the past 6 months.
* Concurrent use of drugs known to be photosensitizers (e.g., thiazides, tetracyclines, fluoroquinolones, phenothiazines, sulfonamides) because of the possibility of increased phototoxicity.
* Concomitant use of neuromuscular blocking agents. Clindamycin has neuromuscular blocking activities, which may enhance the action of other neuromuscular blocking agents.
* Use of topical anti-acne medications within the past 2 weeks.
* Use of any investigational drugs or treatments during the study or within 4 weeks of the baseline visit.
