Topical Treatment Strategies in Plaque Psoriasis: Emerging Options and Practical Considerations
Plaque psoriasis is a chronic, immune-mediated inflammatory skin disease that affects millions of people worldwide and can significantly impair physical comfort, emotional wellbeing, social participation, and quality of life. Although systemic biologic therapies have transformed the management of moderate-to-severe psoriasis, topical therapies remain the foundation of treatment for the majority of patients encountered in primary care and dermatology practice. They are often used as first-line therapy for mild disease, as adjunctive therapy in more extensive disease, and as maintenance treatment to help sustain remission.

Frequently Asked Questions
Yes. Topical corticosteroids remain a cornerstone of treatment because they provide rapid reduction in inflammation, scaling, and itching. Potency should be selected according to lesion location and severity.
Nonsteroidal agents can reduce cumulative steroid exposure and are often better suited for long-term maintenance and treatment of sensitive areas such as the face, skin folds, and genital region.
Potent steroids are generally used for limited courses during active flares, followed by a step-down or maintenance strategy. Continuous prolonged use increases the risk of skin atrophy and other adverse effects.
Tapinarof is an aryl hydrocarbon receptor agonist, and roflumilast is a topical PDE-4 inhibitor. Both are newer nonsteroidal treatments that target inflammatory pathways involved in plaque psoriasis.
Common reasons include greasy formulations, time-consuming application, cost, lack of immediate improvement, fear of steroid side effects, and difficulty incorporating treatment into daily routines.
Referral is appropriate when disease remains uncontrolled despite optimized topical therapy, involves difficult anatomical sites, significantly impairs quality of life, or requires consideration of phototherapy or systemic treatment.
