Sun Damage: Lentigines are due to localised proliferation of melanocytes. The most common type, solar lentigines, arise in middle age and also result from sun damage (age spots). They are most often found on the face and hands, and are larger and more defined than freckles. Lentigines tend to persist for long periods and don't disappear in the winter (though they may fade).

Sun induced freckle: Solar lentigines are also known as sun-induced freckles or senile lentigo. It is a dark lesion caused by natural or artificial UV radiation. They may be single or multiple. They are benign, but they do indicate excessive sun exposure, a risk factor for the development of skin cancers.
