Efficacy of Red Light in Vitiligo

Vitiligo is a chronic acquired disease characterized by well defined white macules and patches affecting the skin. There are many treatment modalities available for vitiligo, however, none of them cure the disease. Visible red light has been shown to stimulates melanocyte migration and proliferation resulting in repigmentation of vitiligo patches. However, there are only a few studies published on the efficacy of red light in vitiligo. This is a prospective single-blind randomized clinical trial to assess efficacy of red light in the treatment of vitiligo.
