Hyperpigmentation is a common condition that makes some areas of the skin darker than others. Extra melanin creates spots or patches that look brown, black, gray, red or pink. The areas are not painful or itchy, but they can make people self-conscious. Hyperpigmentation is caused by an increase in melanin. Melanin is the natural pigment that gives our skin, hair, and eyes their color. A number of factors can trigger an increase in melanin production, but the main ones are sun exposure, hormonal influences, age and skin injuries or inflammation.
