Mehmet Oz, MD, Cardiology, answeredAge spots are harmless. Also called liver spots, these blemishes appear as brown or gray patches on the hands, arms, face, or any other skin that receives a great deal of exposure to the sun. Age spots may seem worrisome, since they can be easily confused with skin cancer. If you have any doubts about spots on your skin, see a doctor soon.

Age spots are not usually dangerous. The brown-colored, flat patches are technically called lentigines. (Sounds like a lentil in jeans!) Lentigines are not freckles or moles, but they are benign (not cancerous), darkly pigmented patches that typically show up as you age. They can pop up almost anywhere on your body.
The most common type, solar lentigines, are on your hands and face, and whatever skin has been exposed to lots of ultraviolet (UV) rays. The presence of solar lentigines means you probably spent too much time sunbathing (or tanning in a salon) or frolicking on the beach without sunscreen on.
