And
B) A minimum of 20 but not more than 150 non- inflammatory lesions (open / closed comedones) on the face, including nasal lesions.

7. Used systemic retinoids within the previous 6 months or topical retinoids within 6 weeks prior to baseline.
8. Received treatment with estrogens, androgens, or anti-androgenic agents within the previous 12 weeks (Subjects who have been treated with the above agents for more than 12 consecutive weeks prior to start of investigational product are allowed to enrol as long as they do not expect to change dose, drug, or discontinue use during the study).
9. Using any medication that in the opinion of the investigator may affect this clinical study or evaluation of the study.
10. Plan to use medications that are reported to exacerbate acne (e.g., vitamin D, vitamin B12, corticosteroids, androgens, haloperidol, halogens, lithium, hydantoin, and phenobarbital).
