Sun spots are caused by overactive pigment cells known as melanocytes. When the skin is exposed to sunlight, melanocytes produce melanin which protects the skin from harmful UV rays. Melanin causes the skin to turn brown. Sometimes melanocytes produce too much melanin. Over time, high volumes of the pigment can become clumped, forming sun spots.
Sun spots are harmless, yet for cosmetic reasons, people often seek treatment to remove them.
