Have you ever wondered why some parts of your body are different colours - perhaps not because its not that important - maybe.
Why, for example, are our nipples and genitals different colours to the rest of us? And does this serve any purpose?The answers appears to be no, a dermatologist recently explained.
A dermatologist at Columbia University Medical Center in New York said that the change is down to a combination of two things: melanin and hormones.
When a human hits puberty, the spike in oestrogen and testosterone caused the body to create melanin – the amino acid which also gives the colour to our hair.

A woman’s skin can also become darker during pregnancy for similar reason, particularly around the areolas. Moles and freckles often become a more intense shade, while fewer women will experience chloasma which affects the forehead, cheeks and neck.
But Dr Bordone warned that darker skin is also a symptom of diabetes.
