It's possible that you are experiencing a skin pigmentation disorder, which affects the color of your skin. Various shades and colors of human skin are created by the brown pigment, melanin. Skin cells give your skin color by making melanin.

If your body makes too much melanin, your skin gets darker. Increased amounts of melanin can be produced in response to hormonal changes like taking birth control pills. Plus, pregnancy, Addison's disease and sun exposure all can make your skin darker.

Some cases of skin darkening are not related to more melanin but are cuased by abnormal pigments that make their way into the skin. Diseases such as hemochromatosis or hemosiderosis or some drugs that are applied to the skin, swallowed, or injected can cause skin darkening.

I'd suggest that you see a dermatologist to start diagnosing and treating the skin darkening problem. Please let us know how it goes.

Hi
can eating too much oranges cause skin darkening or some vitamin deficiency!? and can these disorders( skin pigmentation disorder,hemochromatosis,hemosiderosis) just involve face for example? what causes such disorders? genetics background?

Non of dermatologists whom I saw diagnosed these disorders by the way, but i would like to know what kindaa conditions may cause such disorders.

Thanks Again
