Brief Summary

Enrollment of subjects with mild to moderate facial acne. Efficacy was assessed by using an Investigator's Global Assessment scale (IGA 5 point scale) and by counting the number of inflammatory and non-inflammatory lesions on the face at Baseline and Weeks 4, 8, and 12.

Safety assessments included the investigator's assessment of local cutaneous tolerance of the treated skin (dryness, non-lesional erythema, peeling, stinging, burning, and itching, vital signs, and adverse events (AEs).

Detailed Description

Enrollment of subjects with mild to moderate facial acne. Subjects with acne lesions of any severity on the chest and/or back (including shoulders) were enrolled provided they had mild to moderate acne on the face. During the 12-week treatment period subjects used the study product twice daily. Subjects were instructed to treat the entire face (and chest and/or back including shoulders, if applicable).

Efficacy was assessed by using an Investigator's Global Assessment scale (IGA 5 point scale) and by counting the number of inflammatory and non-inflammatory lesions on the face at Baseline and Weeks 4, 8, and 12.

Safety assessments included the investigator's assessment of local cutaneous tolerance of the treated skin (dryness, non-lesional erythema, peeling, stinging, burning, and itching; assessed separately on the chest and/or back including shoulders (if applicable), vital signs (blood pressure and pulse rate), and adverse events (AEs). Urine pregnancy tests were performed at Baseline and at every visit through Week 12 for all female subjects. A physical examination was performed.
