Absolutely. I have large patches on my lower legs/shins for about 15 years. I have taken photos of different areas over past 3 years and have a lots and lots of repigmented spots appear within these patches on my legs. No change in diet but I must say, we sold our business 2 years ago so probs less stress and I spend a lot of time all year round in shorts so as the white patches are not starved of sunlight. I found that before the spots started to repigment, that my vitiligo was dormant in summer and grew in winter so I figured maybe natural sunlight/vitamin d had something to do with it?

I have been having areas on my hands and arms start repigmenting. The only thing I have done differently is take daily vitamin B12 and biotin to help with some temporary hair loss.

Jean-Marie (hi) w colagen please podrias decir el name del colageno?

It is crazy how it will come back sometimes, for a long time before I went 100% I would notice a little pigment come back than disappear. That is interesting about the collagen powder. Maybe you could stop using that and see what happens.
