Hyperpigmentation is a common, usually harmless condition in which areas of skin become darker in color than the normal surrounding skin. This darkening occurs when an excess of melanin, the brown pigment that produces normal skin color, is deposited in the skin.
Ultraviolet (UV) light accelerates the production of melanin. The extra melanin, produced to protect the deeper layers of your skin, creates the darker color of a tan.
Most often, it takes years of sun exposure for these dark spots to occur. They typically develop very slowly over time. Using commercial tanning lamps and tanning beds can eventually result in the same changes. Hormonal factors and genetics also play a role in how susceptible you are to the development of age spots.
