Liver Spots

Lentigines, often called liver spots, due to their brown color, are often induced by aging and  sunlight exposure.  They are flat, vary in size, and are most commonly found on the tops of the hands, forearms, upper torso, face and legs.  They can be successfully treated with a series of pulsed light and laser therapy.
