I've read that pale yellow skin is a symptom of PA/B12-deficiency. My skin has had a yellow tinge for a really long time, and I was wondering how long it might take to resolve, now I'm treating the B12-deficiency?
My skin is naturally very pale. I'm not sure the yellow is pronounced enough that a stranger meeting me would notice anything, but next to members of my family who I previously had the same skin tone as, I look positively fluorescent!
(BTW, liver function tests, etc, all normal)
