30 Interesting and Fun Facts about Human Skin

Learn some fun and interesting skin facts for kids. The skin of both humans and other animals can be much more than just a physical line of defense.



Your skin performs important functions that allow you to live a normal life, you might not notice it happening but you can be sure your skin is doing its part to keep your body healthy. Read on and enjoy the following interesting facts about skin.


1. The skin is the bodies largest organ.

2. It is constantly shedding dead cells. The Average person sheds approximately 1 1/2 Ibs of dead skin cells each year.

3. An average adult has more than 20 square feet of skin. A square inch of the human body has approximately 19,000,000 skin cells.and up to 300 sweat glands.

4.The skin’s thinnest area on the human body, is on the eyelids.

5.Contains a pigment called Melanin. The more melanin the darker the skin, less makes it lighter.

6. It is made up of three layers. The Epidermis is the outer layer, the Dermiss is the middle layer and Subcutaneous is the inner most layer.

7. It protects the body against invasion of bacteria and other foreign objects.

8. It helps to regulate body temperature. Goose bumps are little pimples that helps keep a layer of warm air over your body.

9. Contrary to what is believed, dust is not made up mostly of dead skin cells, there are vastly more sources of dust pollutants floating around the air.

10  Blowin’ in the wind: Globally, dead skin accounts for about a billion tons of dust in the atmosphere. Your skin sheds 50,000 cells every minute.

11.There are at least five types of receptors in the skin that respond to pain and to touch.

12 .One experiment revealed that Meissner corpuscles—touch receptors that are concentrated in the fingertips and palms, lips and tongue, nipples, penis and clitoris—respond to a pressure of just 20 milligrams, the weight of a fly.

13. In blind people, the brain’s visual cortex is rewired to respond to stimuli received through touch and hearing, so they literally “see” the world by touch and sound.

14. “In the buff” became synonymous for “nude” in 17th-century England. The term derives from soldiers’ leather tunics, or “buffs,” whose light brown color apparently resembled an Anglo-Saxon backside.

15. White skin appeared just 20,000 to 50,000 years ago, as dark-skinned humans migrated to colder climes and lost much of their melanin pigment.

16. I see very, very white people: Albinos are often cast as movie villains, as seen in The Da Vinci Code, Die Another Day, The Matrix Reloaded, and—inexplicably—the 2001 flick Josie and the Pussycats. Robert Lima of Penn State suggests that people associate pale-skinned albinos with vampires and other mythical creatures of the night.

17. More than 2,000 people have radio frequency identification chips, or RFID tags, inserted under their skin. The tags can provide access to medical information, log on to computers, or unlock car doors.

18.  Flesh for fantasy: At the Baja Beach club in Barcelona, customers can get an implanted RFID “debit card” and party until their funds are exhausted.

19.  The Cleveland Public Library, Harvard Law School, and Brown University all have books clad in skin stripped from executed criminals or from the poor.

20.  Hopefully, they didn’t have to reprint it: One such volume is Andreas Vesalius’s pioneering 16th-century work of anatomy, De Humani Corporis Fabrica (On the Fabric of the Human Body).
