Age/sun spots are generally caused by skin that has had years of sun exposure. They are not dangerous but can be very unsightly. Our skin has a natural pigment called melanin which is produced by special skin cells called melanocytes. Everyone has the same amount of melanocytes but some skin types make more melanin than others, causing overactive pigment cells, and this can cause darker spots on the skin. Melanin is what helps give us that beautiful suntan, however, detrimentally, ultraviolet rays speed up the production of melanin, causing darker spots on some areas of the skin where more melanin is produced.
