As you age, years of being in the sun start to add up. Liver Spots are
collections of pigment caused by exposure to the sun. Pigment is deposited as a form of
response to injury just like a scar is a response to a cut. The pigment collects in areas
injured because of thin skin or greater sun exposure. Liver Spots also can be caused by
bruising that leaves blood pigments behind. They are most common in people over age 55.
The spots commonly appear on the hands, but can be almost anywhere, especially sun-exposed
areas such as the face, back, arms, feet and shoulders.
