Brief summary:
5 Day study to assess how quickly a topical acne product begins to work.

Detailed description:

Arms:
arm 1: Test product contained 3% benzoyl peroxide in the form of a gel. It was applied on participant's face once-daily at approximately the same time on Days 0, 1, 2 and 3. arm 2: The vehicle gel was similar to the test product except that it did not contain 3% benzoyl peroxide. The vehicle gel served as the negative control and was applied on participant's face once-daily at approximately the same time on Days 0, 1, 2 and 3. arm 3: A commercial product containing 2% salicylic acid that reportedly improves acne lesions was applied on participant's face once-daily at approximately the same time on Days 0, 1, 2 and 3.

Interventions: intervention 1: 3% Benzoyl Peroxide intervention 2: 3% Benzoyl Peroxide Placebo intervention 3: Neutrogena Rapid Clear®
