What's better: laser or phototherapy?

In a recent study researchers assessed effect and safety of different laser and phototherapy treatments, such as excimer laser/light, narrowband UVB, UVA and PUVA.

No significant difference was found between excimer laser and its cheaper alternative NB-UVB in the treatment of vitiligo. 

Laser may produce slightly faster re-pigmentation compared to UVB, while UVA and PUVA are not recommended due to potential side effects.
