Solar lentigines on the forehead
Solar lentigines (len-TIJ-ih-neez) are flat spots of increased pigmentation. They are usually tan, brown or dark brown and darker than freckles. Solar lentigines have oval to round shapes and vary in size. They usually appear on areas most exposed to the sun, such as the scalp, face, hands, arms and upper trunk. Also called liver spots, they are common in older adults. However, solar lentigines can develop in fair-skinned children with heavy sun exposure.
