Age spots usually occur in areas exposed to the sun, like the face. Also known as liver spots, they typically appear as flat brown, grey or black spots and vary in size. Age spots are more common in older adults.
Sun damage is the most common cause, but other possible causes include various forms of ultraviolet (UV) light exposure, such as tanning beds. These spots are likely to appear on the face, back of hands, forearms, shoulders and other areas frequently exposed to the sun.
