Primary Outcome Measures :
  1. Investigator's Global Assessment (IGA) [ Time Frame: week 12 ]
    Proportion of subjects with an assessment of clear or almost clear with at least a 2-grade improvement in IGA at Week 12

  2. Absolute change in lesion count (separately for inflammatory and non-inflammatory) [ Time Frame: baseline and week 12 ]
    Absolute change from Baseline in lesion count on the face at Week 12 (separately for inflammatory and non-inflammatory lesions)

Secondary Outcome Measures :
  1. Percentage change from Baseline in lesion count on the face at Week 12 [ Time Frame: Baseline and week 12 ]
    Percentage change from Baseline in lesion count on the face at Week 12 (separately for inflammatory and non-inflammatory lesions)

  2. assessments of IGA at each time point [ Time Frame: baseline, week 4, 8 ]
    Supportive efficacy variables are the assessments of IGA percentage change at each time point during the treatment period, namely at Weeks 4, and 8.
