3. Subjects have the willingness and ability to understand and provide informed assent/consent to participate in the study and are able to communicate with the investigator. Subjects are willing and able to follow all study directions and to commit to all follow-up visits for the duration of the study. In addition, subjects must be willing to accept the restrictions of the study.

4. A minimum of 5 inflammatory lesions (papules and pustules) on each side of the face, and a minimum of 5 non-inflammatory lesions (open comedones and closed comedones) on each side of the face. Lesions should be relatively symmetrical in appearance on both sides of the face. At least one inflammatory lesion should be measured no smaller than 2 mm in diameter and should be visible on each side of the face in images taken with digital imaging station.

5. Ongoing oral medications (other than those specifically for acne) are acceptable provided subjects are on a stable regimen throughout the study and provided the medications are determined likely to not interfere with study assessments.

6. Subjects will not use medicated cosmetics and/or soaps (including soaps containing antibacterial agents such as benzoyl peroxide, keratolytic agents such as salicylic acid, skin fresheners/astringents or aftershave lotions) for the duration of the study.

7. Subjects who agree not to use any other acne treatment (including prescription and non-prescription medications) on the test site for the duration of the study.

8. Subjects who agree not to change facial cosmetic products during the study.

9. Subjects who agree to only use sunscreen/sunblock agents that are labeled as non-comedogenic.

4. Subjects with any acne cysts or nodules.

5. Subjects with acne conglobata, acne fulminans, secondary acne (e.g. Chloracne, drug-induced acne), or any acne requiring systemic treatment.

6. Subjects with excessive facial hair that may interfere with study assessments.

7. Subjects with other facial skin disorders that may interfere with study assessments.

8. Subjects with a history of skin cancer or actinic keratosis.

9. Subjects who have used tanning devices within one week prior to baseline study visit.

10. Subjects who have applied any topical products (e.g. emollients, sunscreens) or any cosmetics to the face at least one hour prior to study assessments.

11. Use of hormonal oral contraceptives for acne control or for less than 6 months prior to study baseline.

12. Subjects with known allergies, a history of allergy or sensitivity to benzoyl peroxide, or any of the test article components.

13. Subjects using topical or systemic medication within 14 days before the study entry, which could interfere with study assessments. This includes but is not limited to the following: anti-inflammatory drugs (e.g. topical and systemic corticosteroids and systemic antihistamines), anti-acne drugs, topical and oral retinoids, topical antibacterial agents to the face, and any immunosuppressive drugs. Ongoing oral medications not expected to interfere with study assessments are allowed if the subject is on a stable regimen.

14. Subjects who are currently enrolled in another clinical investigation or have been enrolled in an acne trial within a period of 30 days prior to enrollment in this study.
