Do you think that Michael Jakson's song Black or White might have some sort of connection to a disease called Vitiligo, which the late King of Pop suffered himself?
I saw a report on this matter earlier and this chronic disorder of this skin depigmentation as in patches of skin happened to more or less 3% of population in the US and that it is more noticeable with darker skin complexion.
It is said that this disease is hereditary and easily affecting those susceptible to viral disease and diabetic people. The sufferer tend to blister more and sun burnt easily.
One young lady, who had totally changed to fair or white skin told of her predicament during younger years having to braved all of people's labelling, besides children making fun of her skin conditions which she contracted during the early age of 5 years old.
This disease, for those who are not well verse with it -- is not contagious or life threatening although it will effect them socially.
Vitiligo occurs when the melanocytes, the cells responsible for skin pigmentation which are derived from the neural crest, die or are unable to function, although the precise cause of it is complex and not yet fully understood. There is some evidence suggesting it is caused by a combination of autoimmune, genetic, and environmental factors. It is also common in people with thyroid disorders.
This skin conditions will hurt those people contracted by it and will leave an evident impact on one's appearance. Although Michael Jackson's conditions later resulted in a plus point to him because he eventually became totally white all over, some will just be left with the patches which will be obvious surrounding the face, neck and hand area.
Nevertheless, for those who suffered permanent patches, skin camouflage is the most readily available answer to it.
