The secondary outcome measures will be to calculate the percent change in lesion counts and to measure the change in noninflammatory and inflammatory lesion counts.

Inclusion criteria: Clinical diagnosis of acne vulgaris with facial involvement; score of 3 (moderate) on the IGA scale; a minimum of 20 but not more than 100 total lesions (noninflammatory and/or inflammatory) on the face (including the nose) at baseline.
