How are moles formed?

Have you ever wondered why/how? I have! Since.. i realise a new mole on my hand! Hmm, but since my friends and i came across this topic about mole today. I decided to check it out, Yo.

Moles can form at any time even at birth,The color of mole will depend upon the density or concentration of pigment in it or from their parent's genes. Sun exposure may increase the formation of moles. Birth control pills and pregnancy may also play a role in mole formation. Both sun exposure and pregnancy may also darken the color of the mole.

good news! when we are in old age some moles become lighter in color and many times disappear.( Wait uh.. Wait)~

"Age, which is also a contributing factor, also play a part in mole growth. The person in the teen years may start to notice some mole formation."

( Oh.. i see why my hand has a mole, But Sun exposure?! Funny, hahahaha but maybe)

So.. if you don't want moles, try to avoid the sun and eat healthy.
