Freckles are caused by the brown skin pigment called melanin. All of us have some melanin in our skin. Usually, this brown pigment is evenly distributed throughout the skin. But sometimes, small areas in the skin contain cells that make much more melanin than others. When the melanin accumulates in small spots, freckles begin to show. Freckles appear most often on the face, neck and arms. When your skin is exposed to the sun, the sunlight not only darkens the freckles you may already have, but it can also cause new freckles to appear.
