What deficiencies lead to exfoliative cheilitis?

[Deleted member 19766]

Title. I have it and it's very annoying. I've started supplementing B12 but it still won't fuck off. Is this iron? B6? Had it for as long as I can remember btw.
I also have eczema and very dry skin so I'm wondering if that could be why, but my lips are never itchy
Regardless, what are your thoughts and what do you think I should do to fix this curse?
