Age spots are flat brown areas of Skin that may develop, especially on the exposed surface of face and hands, with the coming of middle age. They are sometimes referred to as liver spots.
Two medical terms are used to describe this condition: senile lentigo, or actinic keratosis. Actinic keratosis develops over a lifetime of exposure to the sun, resulting in localised thickening of the Skin. It is potentially malignant.
In an older person, a former beauty mark can turn out to be Hutchinson’s freckle. Often malignant, it should be removed.
