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, or sensitive to salicylic acid, 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. 15.
