Freckle

Freckles, sometimes called ephelides (singular ephelis), are clusters of concentrated melaninized cells which are most easily visible on people with a fair complexion. Freckles do not have an increased number of the melanin-producing cells melanocytes, but instead have melanocytes that overproduce melanin granules (melanosomes) changing the coloration of the outer skin cells called (keratinocytes). As such, freckles are different from lentigines and moles.
