Vitiligo is an autoimmune disease and if you have vitiligo, odds are you have other autoimmune issues as well.
I have been lucky (knock on wood) so far, it started on my armpits and goes around to my back slightly and then down in big sections of my trunk. The corners of my lips are white and really shows up when I get tan. Nothing so far on my face, just the lips and I hope it stays that way but truly, I know it's coming.
The armpits, the skin is silky soft and the hair is totally white and fine.
My mom had it, she had it so bad that she only had splotches of brown here and there. When I was a kid i used to say she looked like a cow. What kids would say..geeze.
But in answer to your question I would just use a full coverage makeup, Lancome has a good one with full coverage. Me, I would not use anything pharmacutical on my face, being autoimmune, chemicals aren't a good thing to seep into your body.
