Hello a year ago i worked in southeast georgia, usa, at a gas station as a college student. I had never seen so much vitiligo in my life, i looked it up because the only vitiligo i knew of was michael jackson and the model winne harlow, but suddenly many customers appeared to have this condition, knowingly and unknowingly. Is it caused by sun? Is it stress? I would say this was small poor town with many passerbys, truckers, all kinds of people, black white mexican. I think in total i saw a handful of my customers everyday that it. I look up the numbers and it says only 2% of the usa has it, any guesses as to why this sort of condition was so prevalent?
