Primary Outcome Measures
NameTimeMethod
Absolute Change From Baseline in Mean Noninflammatory Lesion Count to Week 12Baseline (Day 0), Week 12

Noninflammatory lesions were defined as follows: Open comedones (blackhead) - plugged hair follicle with dilated/open orifice, black in color; and Closed comedones (whitehead) - plugged hair follicle: small opening at skin surface. For noninflammatory facial lesions, open and closed comedones were recorded as a single count.

Absolute Change From Baseline in Mean Inflammatory Lesion Count to Week 12Baseline, Week 12

Inflammatory lesions were defined as follows: Papule - a solid, elevated lesion less than 5 millimeters (mm); and Pustule - an elevated lesion containing pus less than 5 mm. For inflammatory facial lesions, papules and pustules were recorded as a single count, while nodular lesions were counted and recorded separately.

Percentage of Participants With Treatment Success at Week 12Baseline, Week 12

Treatment success was defined as at least a 2-grade reduction from Baseline in EGSS score and an EGSS score equating to "Clear" or "Almost Clear". EGSS was based on a 5-point scale ranging from 0 to 4; where 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, and 4 = severe.
