3. Diagnosis of hidradenitis suppurativa (HS) for at least 3 months prior to the screening visit.
4. Mild to moderate HS (hidradenitis suppurativa) at the Baseline Visit (using the HS-PGA/Hidradenitis Suppurativa Physician's Global Assessment scale ).
5. Total hidradenitis suppurativa lesion count (abscess, fistulas, nodules, papules, and/or pustules) of at least 5 at the baseline visit.
6. Agreement to NOT use topical and/or systemic antibiotics for treatment of HS (hidradenitis suppurativa) for the duration of the study.
7. Agreement to NOT use a diluted bleach bath or topical antiseptic washes containing chlorhexidine gluconate or benzoyl peroxide. Note: Over-the-counter non-medicated soap and water is allowed.
8. For women of childbearing potential: agree to remain abstinent (refrain from heterosexual intercourse) or use a highly effective contraceptive method during the treatment period and for at least 30 days after the last application of study drug.
