Age spots are sun damage spots that are flat, brown, gray, or black. They typically appear on sun-exposed areas such as the backs of your hands and your face. The term “age spots” can also refer to liver spots, senile lentigo, solar lentigines, or sunspots.
It is believed that sun damage spots are caused by too much time spent outside in the sun. Skin melanin production is accelerated by exposure to ultraviolet light from the sun. The darker the skin becomes, the more melanin there is in that area, this is called hyperpigmentation. These age spots can be removed by laser.
