Reason for Skin Darkening
Darkened skin or hyper pigmentation, happens when there is overproduction of melanin, melanin is the pigment normally found in the skin, increase in melanin gives dark colour to the skin. Darkened skin can develop in people of all races.
Many of us suffer from hyper pigmentation these days – a common and distressing skin condition – marked by the presence of uneven dark patches in an otherwise even skin tone.
That dark spot, scar or dull patch is inevitable especially with sun becoming harsher day by day. Our skin tone is determined by the pigment melanin – a substance produced by special cells called melanocytes. When these cells overproduce the amount of melanin hyper pigmentation ensues. This skin condition is caused by excessive sun exposure, hormonal changes, genetic factor or drug reaction. Sometimes, another skin condition called acne vulgaris (severe acne/pimples) also leads to hyper pigmentation. Each one of us would have experienced hyper pigmentation in smaller amounts, sometime or the other, in form of dark spots patches, birthmarks, moles and ageing spots. Managing it becomes easier with an early detection of the problem.
Causes of dark skin
Heredity: People who have a dark skin will also have children with dark skin. The genes seems to pass on from generations to generations.
Skin disorders: Certain disorders like Acne vulgaris, Lichen Simplex Chronicus or simply ‘LSC’ may causes skin darkening.
Sun Rays: Nature has powered human body to protect itself from harmful effects of sun rays. Over exposure to sun rays causes skin to tan, this is a natural mechanism, where skin produces more quantity of melanin to prevent the UV rays of sun to penetrate inside skin.
Hyper pigmentation: Skin with too much melanin is called hyper pigmented skin. This might be a cause due to hormonal changes, excessive sun exposure, genetic factors, acne or drug reactions. Each one of us has experienced hyper pigmentation in smaller amounts, sometime or the other, in form of dark spots patches, birthmarks, moles and ageing spots.
