Sun and age spots are concentrations of melanin in the skin. The size and shape of these spots can vary, and may also be slightly elevated on the skin’s surface. They are most commonly referred to as freckles and liver spots. These spots are all considered to be benign.
Freckles are most commonly the result of genetics or exposure to the sun. Freckles that are caused by sunburns have irregular borders and are normally darker brown than those that are caused by genetics. Sun and liver spots are usually caused by excessive sun exposure. They normally appear on areas of the body that are frequently exposed to the sun, like the face, hands, shoulders, arms, legs, and feet. They can also vary in color, from a light brown to black.
