Severity of acne vulgaris was assessed by Investigator Global Assessment (IGA). The IGA score is a static evaluation of the overall severity or "average" degree of severity of a participant's disease by the Blinded Evaluator taking into account all of the participant's facial acne lesions as the participant appears on the day of the evaluation. Overall severity of acne was assessed using a five-point scale where 0=Clear, 1=Almost Clear, 2=Mild, 3=Moderate, and 4=Severe. Low score represented best outcome and higher score value indicated worst outcome.

The IGA score is a static evaluation of the overall severity or "average" degree of severity of a participant's disease by the Blinded Evaluator taking into account all of the participant's facial acne lesions as the participant appears on the day of the evaluation. Overall severity of acne was assessed using a five-point scale where 0=Clear, 1=Almost Clear, 2=Mild, 3=Moderate, and 4=Severe. The IGA treatment "success" was defined as at least a two-point improvement in IGA score relative to Baseline.

Inflammatory lesion count (ILC) included papules (raised inflammatory lesions with no visible purulent material) and pustules (raised inflammatory lesions with visible purulent material).

The ILC included papules (raised inflammatory lesions with no visible purulent material) and pustules (raised inflammatory lesions with visible purulent material).

The non-inflammatory lesion count (NILC) included open and closed comedones.

The NILC included open and closed comedones.

Sebum measurement was conducted on the right and left side of the face. The sebum measurement represented the sebum score of saturation of the film and had a range of 0 to 99, where 99 equated to very oily skin.

Transepidermal Water Loss (TEWL) was conducted on the right and left side of the face.

An adverse event is any untoward medical occurrence associated with the use of a drug in participants, whether or not considered drug related.

The local skin reactions (LSRs) included erythema, edema, scaling/dryness, burning/stinging, pruritus, erosion, and pain) were assessed. Erythema, edema, scaling/dryness, and erosion were assessed by the investigator and burning/stinging, pain, and pruritus were assessed by the participant. Assessments was made using a 4-point ordinal scale where 0=absent, 1=mild (slight, barely perceptible), 2=moderate (distinct presence), and 3=severe (marked, intense). Here, lower point represented no reaction and higher points represented severe reactions.The LSRs were assessed both before and 15 minutes following test article application.
