This study is a 12-week double-blind, vehicle-controlled treatment study in which subjects will be randomized to receive tapinarof cream, 1% or vehicle cream once daily for 12 weeks. At the end of the 12-week study treatment, qualified subjects completing the study will have the option to enter a separate open-label, long-term safety and efficacy study for an additional 40 weeks of treatment with tapinarof cream, 1%. Subjects who do not enroll in the open-label long-term study will complete a follow-up visit approximately 4 weeks after end of treatment in this study (at Week 16).
