i went the other way, i had bad vitiligo on my face, two large circles around the size of a cup on either cheek and areas on eyebrows etc I went on holiday for 3 weeks to a hot country and deliberately didn't put any sunblock on the pigmented areas, just topical steroids ( dermovate ). I sat in the sun at the beach for long periods of time and the vitiligo areas burnt, scabbed over, and after the scabs went they repigmented. Im not saying its from avoiding using the sunblock, i'd been using steroids for several months on those areas prior to the holiday and the part of England i live in had been dark over winter so it may well have been any number of combinations of factors. I've repeated the experiment of not using sunblock on some parts of my body and using it on others i've found for my body, not using sunblock leads to burns on vitiligo areas and partial repigmentation in some areas. That being said lips and fingertips are slow to respond. This isn't scientific evidence though, just personal observations on what happened to me and i would avoid drawing conclusions from it.

What time of the day it happened?
What do you mean affected? Burning?
What SPF do you use?
