Results of the HI‐Light Vitiligo Trial: a clinical trial of corticosteroid ointment and home‐based narrowband ultraviolet light for vitiligo

Vitiligo is a skin condition that causes loss of pigment (white patches) on the skin. It affects 1–2% of the world’s population. The HI‐Light Vitiligo Trial aimed to find out whether treating vitiligo at home with a particular type of ultraviolet light (NB‐UVB), either by itself or with a steroid ointment, is better than treatment using a steroid ointment on its own.
