Which pigmented lesions can be treated with laser?

The most commonly treated conditions are solar lentigines, also known as "age spots," "liver spots" or "sun spots"; cafe' au lait birthmarks; and freckles. These benign pigmented lesions are due to an excess of pigment in the skin, usually due to sunlight exposure and congenital factors. Age spots may appear as enlarged light freckles on the face and hands. Cafe' au lait birthmarks may appear as light brown markings anywhere on the body and can be quite large.
