Pigmentation caused by sun exposure, aging, and various medications. Age spots also known as sun spots or liver spots are small, flat dark areas on the skin. They vary in size and usually appear on areas exposed to the sun, such as the face, hands, shoulders, and arms.
Age spots are very common in adults older than 50, but younger people can get them if they spend time in the sun.
Age spots can look like cancerous growths. True age spots don't need treatment, but they are a sign the skin has received a lot of sun exposure and are an attempt by your skin to protect itself from more sun damage. For cosmetic reasons, they can be lightened or removed.
Age spots may affect people of all skin types, but they're more common in adults with light skin. Unlike freckles, which are common in children and fade with no sun exposure, age spots don't fade.
