Causes of Age SpotsAlthough age spots are usually caused by accumulated exposure to the sun’s ultraviolet (UV) light, they may also be the result of using tanning beds/lamps; trauma or injury; or genetic predisposition. People with light skin are more likely to develop age spots, as are those with a history of frequent sunburn or sun exposure.
