Eligibility
Inclusion criteria
1. Male or female at least 9 years of age and older; 2. Written and verbal informed consent must be obtained. Subjects less than age of consent must sign an assent for the study and a parent or a legal guardian must sign the informed consent (if subject reaches age of consent during the study they should be re-consented at the next study visit); 3. Subject must have a score of 3 (moderate) or 4 (severe) on the Evaluator's Global Severity Score (EGSS) assessment at the baseline visit; 4. Subjects with facial acne inflammatory lesion (papules, pustules, and nodules) count no less than 20 but no more than 50; 5. Subjects with facial acne non-inflammatory lesion (open and closed comedones) count no less than 25 but no more than 100; 6. Subjects with two or fewer facial nodules
Exclusion criteria
1. Use of an investigational drug or device within 30 days of enrollment or participation in a research study concurrent with this study; 2. Any dermatological conditions on the face that could interfere with clinical evaluations such as acne conglobata, acne fulminans, secondary acne, perioral dermatitis, clinically significant rosacea, gram-negative folliculitis, dermatitis, eczema; 3. Any underlying disease(s) or some other dermatological condition of the face that requires the use of interfering topical or systemic therapy or makes evaluations and lesion count inconclusive; 4. Subjects with a facial beard or mustache that could interfere with the study assessments; 5. Subjects with more than two (2) facial nodules; 6. Evidence or history of cosmetic-related acne

|---|---|---|
| Absolute Change in Mean Lesion Counts at Week 12 | Baseline to Week 12 | For noninflammatory facial lesions, open comedones (blackheads) and closed comedones (whiteheads) were recorded as a single count. For inflammatory facial lesions, papules (solid, elevated lesion less than 5 mm) and pustules (elevated lesion containing pus less than 5 mm) were recorded as a single count, while nodular lesions (palpable subcutaneous lesion greater than 5 mm) were counted and recorded separately. |

Evaluations were scored on a scale of 0-4, with 0 being clear and 4 being severe. |
