Acne Vulgaris, Post Inflammatory Hyperpigmentation
Conditions
Brief summary
This is a single-center, open label pilot study. The study is comprised of 5 study visits; Screening, Baseline, and Weeks 4, 8, and 16. All subjects will receive Onexton at Baseline and be instructed to apply the gel once daily to the face. The investigators will evaluate Investigator Global Assessment of acne (IGA), total lesion count, inflammatory lesion count, non-inflammatory lesion count, Investigator Global Assessment of Post-Inflammatory Hyperpigmentation and distribution of Post-Inflammatory Hyperpigmentation, adverse events and concomitant medications.

Eligibility
Inclusion criteria
i. Outpatient, subjects of skin of color, age 12 or older. Female subjects of childbearing potential must have a negative urine pregnancy test result at Baseline and practice a reliable method of contraception throughout the study; A female is considered of childbearing potential unless she is: * postmenopausal for at least 12 months prior to study drug administration * without a uterus and/or both ovaries; or * has been surgically sterile for at least 6 months prior to study drug administration Reliable methods of contraception are: * intrauterine device in use ≥ 90 days prior to study drug administration; * barrier methods plus spermicide in use at least 14 days prior to study drug administration; or * vasectomized partner \[Exception: Female subjects of childbearing potential who are not sexually active will not be required to practice a reliable method of contraception. These subjects may be enrolled at the Investigator's discretion if they are counseled to remain sexually inactive during the study and understand the possible risks in getting pregnant during the study.\] ii.
