Stimulating Facts About Skin

“Skin care is like dieting. You have to invest time and effort. There is no instant miracle cure". -K. Grant

Skin is the largest human organ, protecting our bones and muscles from the outside elements. We decorate our skin with makeup, tattoos, or piercings, pamper it with lotions, and drape it in various clothing. Our skin has a lot to say about our health, lifestyle, and age.

1. Total Coverage

The average person has two square meters of skin. Skin makes up about 15% of body weight, and is the thickest on the feet, and the thinnest on the eyelids.


2. How Many Again

The average adult has more than 11 miles of blood vessels for their skin, which provide oxygen and other resources to your body's 35 billion skin cells. In a single square inch of skin alone, there are about 19 million cells and 625 sweat glands!

3. Old Skin Heaven

We shed nearly 30,000 to 40,000 skin cells every minute. In fact, more than half of the dust in your home is made up of old skin. Old skin also makes up around a billion tons of dust within the earth’s atmosphere.

4. Merely A Scratch

When the skin is exposed to friction or pressure repeatedly, it typically becomes thicker by forming a callus at the site. Sin that suffers sever damage develops scar tissue to heal itself. Scar tissue differs from normal skin, because it doesn’t have hair or sweat glands.

5. Feeling Brand New

Skin (most specifically the outer layer of skin called the epidermis) renews itself every 28 days.  There are also more than 1,000 species of bacteria that call your skin home. On surfaces like the face, which are more prone to being oily, up to 500 million bacteria can be found on the surface.

6. A Sweaty Situation

When the weather is hot, the sweat glands in skin can produce up to 3 gallons of sweat a day. The eardrums, nail bed, margins of the lips, and tips of the weenie do not sweat. Fatty secretions produced by the apocrine sweat gland, as found under the armpits and the genital region, are the reason for body odor in those areas.

8. The Power Of Touch

Fingerprints help people get a better grip on things, by increasing friction. Some people may never develop fingerprints. This is a result of either a genetic defect caused by Naegeli Syndrome or Dermatopathia Pigmentosa Reticularis.

9. Scientific Classification

Skin is known by the more scientific name cutaneous membrane. Composed of three different layers, the skin is made up of the epidermis, the dermis, and subcutis.

10. A Range Of Colors

Melanocytes are tentacle-shaped cells in the human body that are responsible for the level of melanin, giving skin its color. Eumelanin is dark brown or black in color. Pheomelanin is red or yellow. These two types of melanin are responsible for giving human skin its unique color and hue. People who have albinism, which occurs in 1 out of 110,000 births, do not have any melanocytes.

12. Standing On End

Goose bumps tend to happen when the skin feels a little chilly, or something eerie takes place. Since every hair on the skin is attached to a small muscle, known as pili, external stimuli like cold temperatures or heightened emotions cause the pili to react. When the hair stands on end in response, you experience goose bumps.

13. To Save Your Skin

When a sunburn happens, the sun does not damage skin cells enough to cause them to deteriorate--not without a little help anyway. It's actually self-inflicted deterioration. When UV rays damage or change the DNA of our skin cells, the DNA will "direct" the cell to destroy itself to prevent the risk of cancer. ‘Desquamation’ is the term for skin peeling, which is typically a result of sunburn.

14. Dangerous Paper

There are different types of receptors on varying parts of the skin. A paper cut hurts a lot because it doesn't cut deep enough to bleed, and because they expose the skin’s pain receptors to the open air.

15. Escaping By Their Skin

The African spiny mouse is capable of shedding up to 60% of their skin on their back to escape a predator. Instead of making scar tissue, this mouse can regrow hair follicles, sweat glands, fur, and skin.

16. Lime A-Way

It might not be such a good idea to make a margarita outside. The skin can actually suffer second degree burns and be discolored if lime juice is left on the hands on a sunny day. This phenomenon is called "margarita dematitis".

17. Smells Like Old People

Thanks to a chemical called 2-nonenal, which is secreted by older people through the skin, elderly people smell different than young people.

18. A Dubious Skin Care Ingredient

The skin, often removed during a circumcision, is used as an ingredient for high-end luxury skin creams. Fibroblasts are grown on the skin and then harvested for cosmetic uses. One skin can be used for many years in order to produce face creams.

In fact, an infant’s skin has special cell properties, similar to those found in stem cells. After circumcisions, hospitals often sell foreskins to private companies, sometimes for thousands of dollars a piece. They're also used for cosmetic testing, and for skin grafts, which can save the lives of burn victims.

19. Skin Problems

The sunfish is highly susceptible to getting skin parasites. Occasionally, the sunfish will go to the surface of the water to get the attention of a seabird. The seabird luckily will come down and dig out worms and other troublesome parasites out of the sunfish’s skin.

20. Leave Some Hair Down There

Shaving hair from private area can increase the risk of contracting an STD. Since shaving causes many cuts on the skin, it gives viruses and bacteria an easier entrance into the body. Yikes!

21. A Biting Obsession

Dermatophagia is the name for the impulse control disorder, describing people who constantly bite the skin around their fingernails, or the inside of their cheeks. The disorder is connected to obsession and anxiety.

Later on, writers and poets used the phrase to refer to skin that was a light brown-yellow in color. Eventually, "in the buff" was more commonly used to mean someone was undressed from the 17th century on.

26. Some Macabre Fashion

In Iceland in the 17th century, there was a form of magic involving "necropants". These pants would be created using the flayed skin of a friend’s body and a stolen coin from a widow. The skin of the legs would be worn as pants, with a coin positioned on the scrotum. This was believed to bring wealth to the wearer of the necropants.
