Low-dose UVB therapy is comparable with conventional UVB phototherapy for treatment of vitiligo: A pilot study

UVB phototherapy is currently considered as the treatment of choice for vitiligo [1]. UVB is also used for treating inflammatory conditions including psoriasis. Although the major goals for treating vitiligo and psoriasis are different: one aims to bio-stimulate while the other aims to immune modulate, respectively, the protocols of phototherapy are surprisingly similar. More specifically, for narrow-band UVB (NBUVB) treatment of vitiligo, lesion repigmentation is associated with melanocyte precursor cell activation [2].
