Moles, also known as nevi, are common skin growths that appear as small, dark brown spots on the skin.
What Causes Moles?
Moles are primarily caused by clusters of pigment-forming cells called melanocytes.
How Melanocytes Form Moles
- Melanocytes are responsible for producing melanin, the pigment that gives skin its color.
- Instead of being evenly distributed, these cells can sometimes cluster together.
- These clusters create the visible spots we know as moles.
When Do Moles Appear?
Most people develop moles during childhood and the teenage years.
Typical Number of Moles
- An average person might have 10 to 45 moles throughout their life.
Summary
In summary, we have moles because of localized clusters of melanocytes, the cells that produce skin pigment. These growths are most common during childhood and adolescence, with most people having a range of moles on their skin.
