INTRODUCTION: Vitiligo is the most common type of depigmented skin disease. Cellular oxidative stress caused by reactive oxygen species (ROS) has been implicated in the pathogenesis of vitiligo. Nuclear factor E2-related factor 2 (Nrf2)/antioxidant response element (ARE) pathway plays an important role in melanocytes against hydrogen peroxide (H(2)O(2)) induced oxidative stress. In addition, vitexin may protect vitiligo by inhibiting oxidative stress and inflammation. OBJECTIVE: In the present study, we aimed to investigate the antioxidant effe...
