Abstract

Vitiligo is a disorder of pigmentation affecting about 1% of the global population. It is a psychologically devastating disease with suboptimal treatment options. Narrowband ultraviolet B (NB-UVB) phototherapy has become a first-line choice for treating generalized disease. In recent years, topical calcineurin inhibitors, vitamin D analogues, antioxidant agents and other therapies have been combined with NB-UVB to improve its efficacy. This article will address what is known about the mechanisms of action of these treatments and how they may complement NB-UVB on a cellular level, as well as offer a comprehensive, evidence-based review of clinical outcomes with combination therapies.
