Color of the human skin is due to melanin, the black brown pigment, which is produced by melanocytes in the skin. Changes in pigment level are perceived as changes in skin color, which may be seen both as a loss of color (de-pigmentation), or as an excessive accumulation of pigment (hyper-pigmentation). Such changes in pigmentation may come through as simple influences as the amount of sun exposure, but they are a source of extreme distress when they are due to disease simply because they bring the added distress of having a disease.
Vitiligo is probably the commonest cause of depigmentation and generates a lot of concern due to the fact that it causes not only depigmentation but also makes the skin color very uneven and patchy , and hence unsightly. Other common conditions resulting in depigmentation include, Albinism, Tenia Versicolor, and guttate hypomelanosis and for more info visit http://www.antivitiligo.com/vitiligo/things-like-vitiligo.html.
The Commonest cause of darkening complexion or hyper-pigmentation is excessive exposure to sun, but Melasma is all too familiar to women who have born children. Acanthosis Nigricans is associated with insulin resistance and is fairly common.
We can summarize in the end that pigmentary disorders of the skin are fairly varied in their origin and it is always wise to seek professional help when you notice an un-accountable change in your skin color. For further information visit http://www.antivitiligo.com/
