Re. the colour change in the photos, I read one article from her side where her husband/partner said that she used make up to enhance the colour - one of them looks like she has actually used brown shoe polish, but she maybe just gets make up for the darker skin and uses that?
I have also seen her condition described as "tanorexia", which I object to as it has nothing to do with appetite (orexia) - but if it is a mental health condition then perhaps she cannot see how badly discoloured her skin is, a little like anorexics seem unable to see how thin they are.
