Age spots, also known as liver spots, are skin discolorations associated with exposure to ultra violet radiation from the sun. They come in a wide variety of colors, such as brown, red, and black. Typical patients are over the age of 40 with age spots in areas frequently exposed to sunlight, such as hands, shoulders, forearms, the face and forehead. Usually they cause no health problems, but it’s possible for a skin cancer to look like an age spot, so it’s important to make sure.
