What is a mole? (skin)?

Question

The skin pigmant not the creature. lol I understand it is to do with pigmentation but why do some stick up and others not?

Answer 1

small, congenital spot or blemish on the human skin, usually of a dark color, slightly elevated, and sometimes hairy; nevus.  

Answer 2

Yes, you're right, the color of a mole  (naevus) is due to the amount of pigmentation.  The reason some stick up while others don't is which layer they're located in your skin.

Skin has 3 layers.  The flat brown moles are in the outer, which is the epidermis.  The ones that protrude are in middle layer, called the dermis.

The reason they form:::: that's just one of those unknowns.

Answer 3

no one knows

Answer 4

  

Moles

Moles are growths on the skin. Doctors call moles nevi (one mole is a nevus). These growths occur when cells in the skin, called melanocytes, grow in a cluster with tissue surrounding them. Moles are usually pink, tan, brown, or flesh-colored. Melanocytes are also spread evenly throughout the skin and produce the pigment that gives skin its natural color. When skin is exposed to the sun, melanocytes produce more pigment, causing the skin to tan, or darken.

Moles are very common. Most people have between 10 and 40 moles. A person may develop new moles from time to time, usually until about age 40. Moles can be flat or raised. They are usually round or oval and no larger than a pencil eraser. Many moles begin as a small, flat spot and slowly become larger in diameter and raised. Over many years, they may flatten again, become flesh-colored, and go away
