Age spots are rounded, flat parts of the skin with a light brown to black color that have sharply defined borders. Also called liver spots, they commonly occur on the face and back of the hands but can be found on any part of the body.
Age spots are formed by a concentrated increase in pigment in an area of the skin. As their name suggests, age spots are more common on those of us more advanced in years. They can occur on people of any age though, including children. Age spots are more prevalent on people who have spent a lot of time in the sun and are mainly caused by exposure to UV rays. This exposure can also come from prolonged use of tanning beds, which have been tied to an increased risk of skin cancer. Although age spots are harmless, they are sometimes found along with signs of cancer or pre-cancer since both can be the result of spending a lot of time in the sun.
