Everyone has moles, sometimes 40 or more. Most people think of a mole as a dark brown spot, but moles have a wide range of appearance.
At one time, a mole in a certain spot on the cheek of a woman was considered fashionable. Some were even painted on. These were called "beauty marks." However, not all moles are beautiful. They can be raised from the skin and very noticeable. They may contain dark hairs or they may be dangerous.
Moles can appear anywhere on the skin, alone or in groups. They are usually brown in color and can be various sizes and shapes. The brown color is caused by melanocytes, special cells that produce the pigment melanin.
