Eligibility criteria:
inclusion criteria: 1. participants legally competent to sign and give informed consent or, in the case of adolescents, assent with consent of a parent(s) or legal guardian, as required by local laws. 2. males and females ages 18 years to 70 years (inclusive) at the time of consent. 3. clinical diagnosis of facial rosacea as confirmed by the investigator. 4. subjects must have moderate to severe rosacea (as per iga score) and at least 15 and not more than 75 inflammatory facial papules and pustules. 5. subjects must have no more than 2 nodules on the face. 6. subjects must have a definite clinical diagnosis of facial rosacea severity at least grade 3 as defined below:score grade definition 0 clear no inflammatory papules or pustules 1 almost clear few inflammatory papules or pustules 2 mild several inflammatory papules or pustules 3 moderate moderate number of inflammatory papules or pustules and no nodules 4 severe many inflammatory papules or pustules, and up to 2 nodules nodules will be reported separately and not included in the inflammatory lesion counts. 7. subjects must have presence or history of erythema and/or flushing on the face. 8. subjects willing to minimize external factors that might trigger rosacea flare-ups (eg, spicy, thermally hot foods and drinks, hot environments, prolonged sun exposure, strong winds, and alcoholic beverages). 9. subjects who use make-up must have used the same brands/types of make-up for a minimum period of 14 days prior to study entry and must agree to not change make-up brand/type or frequency of use throughout the study. 10. females of childbearing potential (focbp) must have a negative serum pregnancy test at screening (visit 1) and a negative urine pregnancy test at baseline (visit 2). in addition, sexually active focbp must agree to use at least one form of highly effective contraception throughout the trial. highly effective forms of contraception include: oral/implant/injectable/transdermal contraceptives, intrauterine device, and partner's vasectomy. if barrier methods are used (e.g., condom with spermicide, diaphragm with spermicide), then 2 forms of conception are required in association with spermicide. the use of abstinence as a contraceptive measure is acceptable as long as this is a consistent part of a lifestyle choice and an acceptable backup method has been identified if the subject becomes sexually active. 11. females of non-childbearing potential must either be pre-menarchal, or post-menopausal with spontaneous amenorrhea for at least 12 months (post-menopausal status should be confirmed with fsh testing) or have undergone surgical sterilization (permanent sterilization methods include hysterectomy, bilateral oophorectomy, hysteroscopic sterilization, bilateral tubal ligation or bilateral salpingectomy). 12. subjects in good health as judged by the investigator, based on medical history, physical examination, vital signs, serum chemistry labs, hematology values, and urinalysis. 13. subjects are considered reliable and capable of adhering to the protocol and visit schedule, according to the judgment of the investigator. exclusion criteria: 1. subjects with any serious medical condition or clinically significant laboratory, vital signs, or physical examination abnormality that would prevent study participation or place the subject at significant risk, as judged by the investigator 2. subjects who cannot discontinue medications and treatments prior to the baseline visit and during the study according to excluded medications and treatments (table 1). 3. subjects who have unstable rosacea. 4. presence of any skin condition on the face that would interfere with the diagnosis or assessment of rosacea. 5. moderate or severe rhinophyma, dense telangiectasia or plaque-like facial edema. 6. excessive facial hair (eg, beards, sideburns, moustaches, etc.) that would interfere with diagnosis or assessment of rosacea. 7. history of hypersensitivity or allergy to the study drug or of any other component of the formulation. 8. severe erythema, dryness, scaling, pruritus, stinging/burning, or edema. 9. active ocular rosacea (eg, conjunctivitis, blepharitis, or keratitis) of sufficient severity to require topical or systemic antibiotics. 10. use within 6 months prior to baseline of oral retinoids (eg, accutane®) or therapeutic

investigator within 6 months of study entry. 21. subjects who have received oral roflumilast or other pde4 inhibitors (apremilast) within the past 4 weeks. 22. subjects who have a history of or currently active depression, suicidal ideation, or suicidal tendencies as determined by verbal medical history. 23. subjects with seborrheic dermatitis/rosacea overlap. 24. subjects who are unwilling
