The skin throughout the body has a similar color, except in some parts, such as the nipples, lips, vulva or penis. Here is why it is so.

You have probably ever wondered why certain parts of your body, such as the penis and the nipples on the chest have a different color compared to the rest of the skin, Telegrafi reports.

Until recently, it was not known if this had any function or purpose, but now we know that it has no purpose at all. That's what it's about.

The nipples and penis have a darker color due to the influence of hormone especially in puberty.

Why are these body parts brighter before puberty?

- Hormones regulate the work of melanocytes (cells that produce the pigment melanin), so it is logical that hormones affect the color in that part of the body to be darker - says dr. Cameron Rokhsar, dermatologist from New York.

Considering that we are talking about primary and secondary genital characteristics, without which there would be no sex, therefore not even babies by themselves, only when we grow up, they become important, because they have the role that to draw the attention of the opposite sex to what we are ready for "mating".

Nipples are brighter until puberty, and only then become darker under the influence of hormones, says Dr. Lindsay Borden

For this reason, most children when they are small have shiny hair, while when they grow up, under the influence of hormones, their hair becomes darker. The same thing happens with eye color. /Telegraph/
