INTRODUCTION
Plaque psoriasis, or psoriasis vulgaris, is a chronic, debilitating, inflammatory disease,1,2 characterized by well-defined erythemato-squamous plaques surrounded by normal skin.2 Various treatments are available for psoriasis, including topical treatment (considered first-line treatment) for mild-to-moderate disease and phototherapy or systemic/biologic agents (considered first- or second-line treatment) for moderate-to-severe disease.1
Despite the numerous treatment options for psoriasis, maintaining long-term control remains a challenge, due to the relapsing nature of the disease, and many patients remain untreated or undertreated.3 Currently, topical psoriasis treatment relies on a reactive approach to disease relapses, as opposed to a long-term proactive management approach aimed at maintaining disease remission.4 Psoriasis is a chronic disease that requires a safe long-term treatment strategy.
