Solar lentigo is another name for age spots which can be roughly translated to sun spots. Age spits mostly occurs due to sun exposure and this is why it is most visible on face, arms and neck.

Medically termed lentigos, liver spots measure up to one inch in diameter and can be found all over the body, but especially on surfaces of the skin that are often exposed to sunlight. This includes the face, hands, shoulders, and arms.

Lentigines: Lentigines (singular: lentigo) are flat, tan to brown oval spots. They are commonly due to chronic sun exposure (solar lentigines; sometimes called liver spots) and occur most frequently on the face and back of the hands.

Lentigines (singular: lentigo) comes from the Latin word for lentil and is the medical term for certain types of darker freckles and sunburn freckles. Lentigines tend to be darker than the common freckle and do not usually fade in the winter.
