Eligibility
Inclusion criteria
* Men and women at the age of 12 or older at the Screening visit. * Those with clinical diagnosis of acne vulgaris with more than 20 non-inflammatory lesions (open and closed comedones) and 12 to 100 (inclusive) inflammatory lesions (papules, pustules and nodules) on the face (forehead, both cheeks, nose and chin).
Exclusion criteria
* Those with more than two nodular acne lesions or any cyst. * Those with the diagnosis of any acne conglobata, any acne fulminans, any chloracne, or any drug induced acne. * Those who have clinically significant abnormal findings or conditions on skin other than acne such as atopic dermatitis, perioral dermatitis, or rosacea that potentially interfere with study assessments according to Investigator's judgment
