🔹 Reading Passage

Moles are small dark spots that can appear on our skin.
You might see them on your arm, face, or back.
Most people have several moles, and they are usually harmless.
But where do they come from?

Our skin is made of tiny cells, and one type is called a melanocyte.
These cells create melanin, the pigment that gives color to our skin, hair, and eyes.
Sometimes, instead of spreading out evenly, melanocytes group together in one spot.
When this happens, a mole forms.
That’s why moles are often brown or black—they contain more melanin than the skin around them.

Some moles are present from birth, but many appear later during childhood or the teenage years.
Sunlight can also affect melanocytes.
Spending a lot of time in the sun can lead to new moles or make existing ones darker.

Most moles are harmless and stay the same for a long time.
But if a mole changes in size, shape, or color, it’s smart to have it checked by a doctor.
Understanding how our skin works helps us take better care of it.
