          -  Patient must have at least eight and not more than fifty inflammatory facial lesions
             (i.e., papules/pustules) and ≤2 nodules on the face. For the purposes of study
             treatment and evaluation, these lesions should be limited to the facial treatment area
             including those present on the nose. Lesions involving the eyes, and scalp should be
             excluded from the count.

          -  Patients must have persistent erythema on the face with moderate (Definite redness,
             easily recognized) to Severe (Marked erythema; fiery red).

          -  Patients must have a mild to moderate score for telangiectasia on the face - Patients
             must have a definite clinical diagnosis of moderate facial rosacea as per the IGE

          -  Patient must be willing to minimize external factors that might trigger rosacea
             flare-ups (e.g., spicy foods, thermally hot foods and drinks, hot environments,
             prolonged sun exposure, strong winds and alcoholic beverages).

          -  Patient must be in general good health and free from any clinically significant
             disease other than rosacea, that might interfere with the study evaluations.

          -  Patient must be willing and able to understand and comply with the requirements of the
             study, apply the medication as instructed, return for the required treatment period
             visits, comply with therapy prohibitions, and be able to complete the study.

          -  Female Subjects of childbearing potential (excluding women who are
             surgicallysterilized or postmenopausal for at least 1 year), in addition to having a
             negative urine pregnancy test, must be willing to use an acceptable form of birth
             control during the study from the day of the first dose administration to 30 days
             after the last administration of study drug For the purpose of this study the
             following are considered acceptable methods of birth control: oral contraceptives,
             contraceptive patches, contraceptive implant, vaginal contraceptive, double barrier
             methods (e.g., condom and spermicide), contraceptive injection (Depo-provera®),
             intrauterine device (IUD), hormonal IUD (Mirena®) and abstinence with a documented
             second acceptable method of birth control, should the patient become sexually active.
             Patients on hormonal contraception must be stabilized on the same type for at least
             three months prior to enrollment in the study and must not change the hormonal
             contraception during the study. Patients who had used hormonal contraception and
             stopped must have stopped no less than three months prior to the study. A sterile
             sexual partner is NOT considered an adequate form of birth control.

          -  All male patients must agree to use accepted methods of birth control with their
             partners, from the day of the first dose administration to 30 days after the last
             administration of study drug. Abstinence is an acceptable method of birth control.
             Female partners should use an acceptable method of birth control as described in the
             above Item Number 10.
