Inclusion Criteria:

Active or stable non-segmental vitiligo at Screening and Baseline visits:

• A clinical diagnosis of non-segmental vitiligo (vitiligo vulgaris or acrofacial vitiligo) for at least 3 months, AND
• Body Surface Area affected (BSA) involvement 3%-90%, excluding involvement of scalp, palms of the hands, soles of the feet, AND
• BSA >= 0.5% involvement of the facial area, AND
• Minimum Facial Vitiligo Area Scoring Index (F-VASI) >=0.5% and Total VASI >=3%
• Must agree that the treatment area will involve 3%-25% BSA
• If receiving concomitant medication for any reason other than vitiligo, must be on a stable regimen (no new drug or dosage changes within 7 days of baseline visit) and willing to remain on stable regimen for duration of the study
• Must agree to stop all other treatments for vitiligo from screening through 1 week after discontinuation of study drug treatment
• Must be capable of giving signed informed consent and comply with the requirements and restrictions as listed in the informed consent document and protocol
• Must agree to avoid exposure to the sun as much as possible and not to use tanning booths, sun lamps, or other ultraviolet light sources other than requested by the study team during the study

Exclusion Criteria:

• Pregnant or breastfeeding females
• Females of childbearing potential who are unwilling or unable to use contraception for the duration of the study and for at least 28 days after the last dose of study intervention
• Other types of vitiligo that do not meet criteria for active or stable or non-segmental vitiligo, including segmental, mucosal, focal, and mixed vitiligo, and those with vitiligo universalis
• Active forms of other hypo- or depigmentation, as detailed in the protocol
• Active forms of inflammatory skin disease(s) associated with hypo- or depigmentation at the time of screening or baseline that, in the opinion of the investigator, would interfere with evaluation of vitiligo or response to treatment
• Leukotrichia in more than 33% of the facial area affected with vitiligo lesions OR leukotrichia in more than 33% of the total BSA affected with vitiligo lesions
• History of transplantation procedure for vitiligo at any point
• History of any skin bleaching treatment for vitiligo or other dermatoses at any point
• Active acute or chronic skin infection requiring treatment with systemic antibiotics, antivirals, antiparasitics, antiprotozoals, or antifungals within 4 weeks prior to first drug application (baseline), OR superficial skin infections within 2 weeks prior to first drug application (NOTE: MAY BE RESCREENED AFTER INFECTION RESOLUTION)
• Known history of severe allergic or anaphylactoid reaction to any PDE4 inhibitors or lidocaine
• Documented lack of response to prior PDE4 inhibitor therapy
• Presence of other severe, progressive, or uncontrolled diseases, including but not limited to renal, hepatic, cardiac, pulmonary, endocrine, immunological/rheumatological, hematological, gastrointestinal, metabolic, neurologic, psychiatric, immunodeficiency (including HIV positive serology), OR significant laboratory abnormalities that would increase risk associated with study participation or interfere with interpretation of study results, or in the opinion of the investigator, the participant is inappropriate for entry into the study, or unwilling/unable to comply with protocol-specified assessments and lifestyle considerations
• Any malignancies or history of skin malignancies, excluding adequately treated or excised non-metastatic basal cell or squamous cell skin cancer, or cervical carcinoma in situ
• Significant trauma or major surgery 1 month prior to screening or considered in imminent need of surgery during the study
• Alcohol or substance abuse within 6 months of screening that in the opinion of the investigator would preclude participation or adherence in the study
• Previous administration of an investigational drug or vaccine occurring within 30 days preceding the first application of study drug used in this study
• Any biologic or immune-modulating agent (including oral JAK inhibitors, PDE4i, other immunosuppressive agents such as oral corticosteroids, calcineurin inhibitors, azathioprine, mycophenolate mofetil) requires a washout period of 8 weeks before screening and through the final safety follow-up visit
• Any topical treatment (such as topical steroids, calcineurin inhibitors, vitamin D analogs, JAK inhibitors, PDE4i) requires a washout period of 2 weeks before screening visit and through the final safety follow-up visit
• Ultraviolet light exposure, including UVB/UVA/PUVA delivered by booth/excimer laser, or tanning bed exposure, requires a washout period of 8 weeks before screening and through the final safety follow-up visit
