1.  Primary:   Change From Baseline in Total Non-inflammatory Lesion Count   [ Time Frame: Baseline to Week 12 ]
  Hide Outcome Measure 1

Measure Type Primary
Measure Title Change From Baseline in Total Non-inflammatory Lesion Count
Measure Description Change from Baseline to Week 12 (Week 12 minus Baseline) in the total non-inflammatory acne lesion count. Facial acne lesion counts consisted of non-inflammatory lesions and inflammatory lesions. The total non-inflammatory acne lesion count is the sum of open and closed comedones, change from Baseline was calculated as the value after Baseline minus the baseline value, and negative changes indicated lesion improvement.
Time Frame Baseline to Week 12  
Safety Issue No  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
