I have had universal vitaligo for approximately 5 years.
I don't have depgimention on my face, but this happens all the time for me on the parts of the body I have lost pigmentation -the colour comes back a bit then fades again. My vitiligo is also getting worse and I'm losing more pigment. I've read that the hormonal changes during menopause can exacerbate vitiligo. And this is what I suspect MAY be the current culprit for me.
