Previous Next 3 of 10 Solar lentigines on the forehead

Solar lentigines (len-TIJ-ih-neze) are flat spots of increased pigmentation. They're usually brown, black or gray and vary in size. And they usually appear on areas most exposed to the sun, such as the face, hands, arms and upper back. These spots, also referred to as age spots or liver spots, are common in older adults. They also occur in younger people who spend a lot of time in the sun without protecting their skin.
