Pigmentation refers to the amount of color within a substance. In the case of human skin, that color, that pigment, is called melanin. Varying concentrations of melanin give us the different shades of skin peculiar to our various geographical races. Melanin is also responsible for the darkening of skin in response to ultraviolet radiation. This darkening, called tanning, is important because without it we would be open to a lot of potential damage from radiation. Consider the fate of people without any pigmentation, albinos, who have to wear protective glasses and sun blocks to walk outside in daylight. Pigmentation serves a purpose, but it can also be responsible for dark spots on our skin that we don't want. Getting rid of that pigmentation is what this article is all about, but just so you know, some of it isn't going away easily.
Getting Rid of Pigmentation
Pigmentation could be a symptom of cancer.
Skin cancer is no joke and a lot of times certain kinds of skin cancer can present with spots of pigmentation in the skin which are unusual. They usually grow more quickly than ordinary liver spots or moles. They will sometimes have more than one shade of brown, whereas a mole will usually be all one shade. They also tend to appear more jagged than normal skin growths. If you notice anything like that growing on your body you should definitely have it checked out by a doctor. It's always better to get it checked than to risk it. Remember to have a friend help or look in a mirror at areas of your body that you don't normally see or you might miss an obvious sign of skin cancer.
