Would Spray Tanning Help Me?

I have never had a spray tan, but one of my law school classmates used to get them all the time. I have vitiligo, which is a skin pigment problem. Where you lose pigment, and your skin goes white. I am fair skinned anyway, so normally it doesn't show, but when I get the least bit of sun, you can see the vitiligo patches. I have medicine t use, two different creams, but one of them is very expensive, so I have slacked off. I need to start again. I would like to get a spray tan to help that problem. I am just not sure if it would help fill in the spot,s or make them more noticeable.
