<h1>How do skin moles develop</h1>

The formation of skin moles starts from skin cells called melanocytes. These cells are responsible for the production of melanin. Melanin is the substance that gives skin and hair its colour.  A skin mole forms when melanocytes pile up or grow abnormally close to each other, rather than being spread evenly on the surface of the skin. There are a few reasons for this to happen. The reasons are listed below:

1) Genetics
2) Hormones secreted by the body ( more common amongst female)
3) Too much exposure to the sun.
