Psoriasis is a disease difficult to cure and is usually recurrent and therefore, a continued management is crucial. An evidence-based approach is important for appropriate treatments of patient with psoriasis. However, there is a lack of response data for the topical treatments in Asian patients with psoriasis, and no treatment guidelines available. Therefore, routine topical treatments, instead of patient-specific treatments, are usually applied, which may result in treatment failure. In this regard, it is imperative to conduct a study to assess topical treatments in Korean patients with psoriasis vulgaris in terms of efficacy and side effects.
