Contribution of Skin Color in Stabilization of Active Cases of Vitiligo by Narrow Band UVB

Vitiligo is a disease in which autoimmunity plays a major role. Multiple treatment options are available, of which narrow-band UVB is a cornerstone, acting through immunosuppression and repigmentation by stimulating reservoir melanocytes. It's expected that this immunsupression is lower in darker skin types, where increased basal melanin might act as a barrier.
