  3. Patients 18 years of age or older must provide Institutional Review Board (IRB) approved written informed consent. Patients under 18 years of age must have IRB approved written informed consent from a parent or legal guardian. Patients 12 - 17 years of age must complete an IRB approved assent form for minors.
  4. Patients must be willing and able to understand the requirements of the study, abide by the restrictions, apply the medication as instructed, and return for the required study visits.
  5. Patients must be in good health and free from any clinically significant disease, other than acne vulgaris, that might interfere with the study evaluations.
  6. Patients who use make-up must have used the same brand of make-up for a minimum period of 2 weeks prior to Baseline and agree to not change make-up brands or types during the study.


  1. Patients who are pregnant, nursing, or planning a pregnancy within the study period.
  2. Patients who have more than 2 nodulo-cystic lesions on the face, excluding the nose.
  3. Patients who have a known hypersensitivity to any ingredients in the test products including clindamycin and benzoyl peroxide.
  4. Patients who have been treated with prescription and/or over-the-counter topical products, or had a procedure performed that may impact study assessments.
  5. Patients who have any systemic or dermatological disorder that has the potential to interfere with the evaluations (e.g., rosacea, seborrheic dermatitis, perioral dermatitis, corticosteroid-induced acne vulgaris, carcinoid syndrome, mastocytosis, acneform eruptions caused by medication, facial psoriasis, facial eczema, etc.).
  6. Patients with clinically significant unstable medical disorders, life-threatening disease, or current malignancies.
  7. Patients who engage in activities that involve excessive or prolonged exposure to sunlight.
  8. Patients who consume excessive amounts of alcohol, abuse drugs, or have any condition that would compromise compliance with this protocol.
  9. Patients who have been treated with an investigational drug or investigational device within a period of 30 days prior to study entry.
  10. Alcoholic toners, astringents, medicated topical preparations (prescriptions and over-the-counter), or medicated make-up on the facial treatment area.
  11. Abrasive cleansers or washes to the facial area.
  12. New cosmetics, or new cleansers applied to the face.
